Data center construction is moving at a pace that puts unusual pressure on every part of the supply chain, including the inexpensive fasteners, nuts, washers, anchors, and other hardware that most project teams would classify as Class C items.
In April 2026, U.S. spending on data center construction reached a seasonally adjusted annual rate of $50.7 billion, representing 2.3% of all construction spend, according to U.S. Census Bureau data. That was more than 37% higher than a year earlier and put data center construction ahead of transportation structures — airport facilities, marine terminals, and mass transit — for the first time.
The massive spend is flowing into enormous facilities filled with racks, raised floors, containment systems, cooling infrastructure, electrical equipment, and mechanical systems. Every one of those systems depends on hardware.
The problem is that Class C hardware is easy to overlook during planning because the individual components are cheap. But when one of them isn’t available at the point of need, its dollar value stops being the relevant measure. By definition, the hardware becomes a critical path item simply because the work around it cannot proceed in its absence.
What Is Class C Hardware?
Class C hardware generally refers to high-volume, relatively low-cost components that represent a small share of total material spend but are consumed frequently throughout an operation or project.
For data center construction, that can include:
- Nuts, bolts, and washers
- Structural fasteners
- Anchoring hardware
- Threaded rod and related hardware
- Rack screws and cage nuts
- Mounting hardware
- Cable management hardware
- Electrical and mechanical installation fasteners
- Racking and support hardware
- Maintenance and repair consumables
The precise classification depends on the project or organization’s purchasing profile. A fastener that represents a minor expense on a multimillion-dollar data center project may nevertheless be essential to completing a specific installation.
That distinction matters. Class C does not mean unimportant. It describes the economics and purchasing characteristics of the item, not its importance to the work.
The Data Center Construction Schedule Changes the Equation
On a conventional project, a missing box of fasteners might be an inconvenience. On a highly coordinated data center build, the same shortage can create a much larger problem.
Construction is typically divided among numerous trades and work packages. Electrical contractors, mechanical contractors, rack installers, structural crews and other teams are often working simultaneously or in tightly sequenced phases. Think of it like a general contractor and subs on a new home build, but on a multibillion-dollar scale, with the nation’s ravenous appetite for data centers to fuel AI at stake.
A crew may be ready to install equipment, but if the required mounting hardware isn’t at the work area, the crew may have to stop. That creates a disproportionate economic consequence.
The missing item may cost only a few dollars. The labor standing idle can cost hundreds or thousands of dollars per hour. A delayed installation also affects downstream crews, inspections, commissioning activities or the schedule for bringing a portion of the facility online.
This is how a Class C component gets onto the critical path. It calls to mind an old adage made popular in the 1700s by Benjamin Franklin in “Poor Richard’s Almanac,” especially considering the part in question:
- For want of a shoe, the horse was lost.
- For want of a horse, the rider was lost.
- For want of a rider, the battle was lost.
- For want of a battle, the kingdom was lost.
- And all for the want of a horseshoe nail.
The risk becomes even more significant as data center construction accelerates, as noted in the Census Bureau statistics cited above.
When demand for construction materials and installation components rises rapidly, procurement teams also have less room for error. A part that was readily available a year ago may have longer lead times or require more advance planning when multiple projects are competing for the same supply.
Where Class C Hardware Shows Up in a Data Center
Class C hardware isn’t confined to one portion of a facility. It can appear throughout the construction and maintenance process.
Racks and equipment
Server racks, cabinets, and other equipment require mounting hardware, including rack screws and cage nuts. The correct thread, size, and configuration matter because equipment manufacturers and rack systems may use different specifications.
Raised floors
Raised-floor systems rely on structural and fastening components that must be available as installation progresses. A missing component can prevent a section of floor from being completed and potentially interfere with subsequent work.
Cable management
Data centers contain enormous quantities of cabling. Cable trays, supports, brackets, and other management systems require mounting and fastening hardware throughout the facility.
Electrical infrastructure
Electrical installations depend on a wide range of fastening and mounting components for equipment, supports, panels, and associated infrastructure.
Mechanical and cooling systems
Cooling systems, piping, manifolds, supports, and related equipment can require significant quantities of nuts, bolts, anchors, threaded rod, and other hardware.
The common thread is simple: the individual hardware items are inexpensive, but the systems that depend on them are not.
Why Data Center Hardware Planning Can Go Wrong
One of the biggest problems with Class C hardware is that it can fall between procurement categories. Project teams naturally focus on large-dollar equipment, long-lead-time electrical components, generators, transformers, cooling equipment, and other materials that can determine whether a project stays on schedule.
The fastener rarely receives the same attention. They may be purchased through multiple subcontractors, ordered in relatively small quantities, or treated as commodities that can be sourced later. That approach can work — until demand suddenly increases.
A data center project can consume thousands of individual fasteners across multiple work areas. If each contractor or project team independently manages its own requirements, the result is fragmented purchasing, inconsistent specifications, emergency orders, and limited visibility into what is actually available on site. Obviously, the cost isn’t the fastener itself but the friction surrounding it.
The Real Cost of a Class C Stockout
Consider a hypothetical example: A contractor needs a particular anchor to complete a portion of a mechanical installation that costs a few dollars. The project doesn’t have enough on hand, so someone has to find another source.
As the installation crew cools its heels, the buyer may have to:
1. Identify the exact specification.
2. Contact a supplier.
3. Confirm availability.
4. Arrange expedited shipping.
5. Process an emergency purchase.
6. Receive the material.
7. Get it to the appropriate work area.
The emergency freight could cost more than the hardware, and the administrative effort likely involves multiple employees. If the component is unavailable from the normal supplier, the replacement must still be checked to ensure it meets the required specification.
For a single occurrence, that may be manageable. Repeated across hundreds of Class C components and multiple construction sites, it becomes a procurement and project management problem.
The Knee-Jerk ‘Buy More’ Response Doesn’t Fly
A common response to stockout risk is to increase inventory. But excessive inventory creates its own problems. Overbuying ties up working capital, consumes storage space and increases the likelihood of having the wrong component in the wrong location. Data center projects also evolve. Specifications can change, designs can be modified, and construction schedules can move.
For these reasons, the objective is not to maximize inventory but to have the right hardware, in the right quantity, at the right location, when the work requires it. That requires a more disciplined approach to Class C hardware management.
What Better Class C Hardware Management Looks Like
An effective program starts by identifying which components are actually being consumed and where. For a data center project, that means developing a defined list of fasteners and related hardware, establishing expected usage, determining appropriate stocking levels and coordinating replenishment with the construction schedule.
The supplier relationship can then extend beyond simply fulfilling purchase orders. Depending on the operation, a managed program might include:
- SKU identification and specification control
- Inventory analysis
- Minimum/maximum stocking levels
- Point-of-use stocking
- Bin stocking
- Kitting
- Scheduled replenishment
- Usage monitoring
- Emergency requirements
- Inventory reporting
- Multisite coordination
The objective is to remove low-value administrative work from project and procurement teams while protecting the availability of components that can hold up higher-value work.
Procurement Should Ask: Who Owns the Problem?
One of the most useful questions a data center operator or contractor can ask a hardware supplier is: If the required fastener isn’t available when the crew needs it, who owns the problem?
If the answer is simply “the buyer needs to place another order,” the supplier relationship is essentially transactional. A more sophisticated Class C hardware program establishes responsibilities in advance:
- Who monitors inventory?
- Who determines replenishment quantities?
- Who verifies specifications?
- Who handles unexpected demand?
- Who provides emergency support?
- Who communicates when supply conditions change?
- Who maintains visibility across multiple sites?
The answers should be established before the project reaches the point where a shortage becomes an emergency.
Class C Hardware Is a Supply Chain Problem, Not Just a Purchasing Problem
The fundamental mistake is to manage Class C hardware according to its unit price. Just because a $1 fastener doesn’t receive the same procurement process as a $100,000 piece of equipment, that doesn’t mean it should receive no management at all.
The right approach recognizes the difference between purchase value and operational value. For data center construction, that distinction is becoming increasingly important. The sector’s construction spending has reached unprecedented levels, while projects are being executed under demanding schedules. As projects become larger and more numerous, the consequences of small supply chain failures can become larger as well.
Class C hardware may represent a tiny percentage of project cost. But if a missing component stops a crew, delays an installation or forces an emergency procurement, its impact on the schedule far outstrips its purchase price.
