Value Collection C703414 Hex Cap Screw 5/8-11 Grade 8 25pk

Product Description

The VALUE COLLECTION C703414 is a 5/8-11 hex head cap screw sized at 2-3/4 inches under the head, manufactured from Grade 8 steel with an uncoated finish. Grade 8 steel delivers high tensile strength, making this fastener well suited for heavy-duty bolted assemblies subject to significant load or vibration. The partially threaded shank conforms to ASME B18.2.1 dimensional standards, with a Unified National Coarse (UNC) thread form. Sold in a package of 25, this screw is a dependable choice for mechanical, structural, and equipment assembly applications where a high-strength inch-series fastener is required.

This cap screw is used across a wide range of industrial, commercial, and trade applications, including HVAC equipment mounting, pump and motor assembly, structural steel connections, and general mechanical fabrication. The 5/8-11 UNC thread is one of the most common heavy-fastener sizes in inch-system assemblies. The partially threaded shank allows for a smooth bearing surface between joined components, which is important when precise clamping force distribution is needed. Installers working in mechanical rooms, equipment pads, and fabrication shops will find this a standard fit for many routine bolting tasks.

Installation Notes

Installation is typically performed by millwrights, pipefitters, HVAC technicians, or general mechanical tradespeople using standard hex wrenches or impact tooling. Always de-energize and lock out equipment before fastener installation or removal on powered machinery. Consult applicable codes and equipment manufacturer torque specifications for the assembly before final tightening. Do not mix inch-series and metric fasteners in the same joint.
