Value Collection MP39110 Hex Head Cap Screw 1/2-13 X 2-1/2 in

Product Description

The VALUE COLLECTION MP39110 is a partially threaded hex head cap screw designed for high-strength fastening applications. It features a 1/2-13 UNC thread size and a 2-1/2 inch length under head. Manufactured from Grade 8 steel, this screw delivers the tensile strength required for demanding mechanical and structural assemblies. The zinc yellow dichromate finish provides corrosion resistance and is visually identifiable as a Grade 8 fastener. It conforms to ASME B18.2.1 standards, making it suitable for applications where dimensional and mechanical compliance is specified. Licensed tradespeople and maintenance professionals working in industrial, mechanical, and commercial construction settings will find this fastener meets the performance requirements of critical bolted joints.

This hex head cap screw is used in a wide range of applications including equipment mounting, structural steel connections, machinery assembly, and mechanical systems maintenance. The partial threading allows for full bearing contact in thicker joint materials, which is standard practice in bolted connections requiring precise clamp load distribution. It is appropriate for use in HVAC equipment bases, pump and motor mounts, pipe supports, and general mechanical assemblies where Grade 8 strength is specified.

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use in any application requiring an ASME B18.2.1-compliant Grade 8 fastener with a 2-1/2 inch grip length.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a properly sized hex wrench or socket. Always confirm the mating nut or tapped hole thread is also rated for Grade 8 service before assembly. Follow applicable torque specifications from the equipment manufacturer or relevant code reference for 1/2-13 fasteners. Inspect threads for damage before installation and do not use damaged or corroded fasteners in load-bearing joints.
