Nuts

Usages for Nuts

Nuts are used in every industry and application that uses threaded fasteners — from ASTM A563 heavy hex nuts on structural bolts in steel construction, to DIN 934 metric hex nuts on machinery, to nylon insert lock nuts on vibrating equipment, to coupling nuts on hanger rod extensions in ceiling systems, to flange nuts on automotive subframes. The selection of nut grade, type, and finish must match the bolt or stud specification and the joint requirements to achieve the intended clamping force and joint reliability.

Nuts for all Industries

Nuts are a fundamental fastener component used across every manufacturing, construction, and maintenance sector. Structural engineers, mechanical designers, OEM assemblers, contractors, and maintenance technicians all specify nuts as standard components in bolted assemblies. Blue Ribbon Fastener maintains a deep nut inventory in the grades, types, and sizes most commonly required across structural, industrial, OEM, and MRO applications, with the volume pricing and delivery speed that production and project buyers need.
