Usages for Grade 8 Hex Cap Bolts, Zinc Yellow, Coarse Thread

Grade 8 hex cap bolts are specified in high-load connections such as heavy equipment assembly, suspension and drivetrain components, and machinery mounting where Grade 5 strength isn't sufficient. The coarse thread pitch speeds assembly and tolerates minor thread damage or debris better than fine thread.
