Value Collection C701808 Hex Head Cap Screw Grade 5

Product Description

The VALUE COLLECTION C701808 is a fully threaded hex head cap screw designed for heavy-duty mechanical and structural fastening applications. Manufactured from Grade 5 steel in an uncoated finish, this fastener carries a 1-1/4-7 UNC thread size with a 3-1/2 inch length under head. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice where consistent thread form and head geometry are required. This screw is installed using a standard hex wrench or socket and is suited for high-load bolted connections in industrial, OEM, and maintenance applications. Sold in a package of 5.

This hex head cap screw is used across a wide range of trade and industrial applications, including mechanical equipment assembly, HVAC structural supports, plumbing infrastructure brackets, and general fabrication work. The fully threaded body allows for maximum thread engagement across the full clamped length, which is useful when fastening thinner materials or when a nut is used as the primary load-bearing element. Licensed tradespeople and maintenance technicians working on equipment assemblies will find this fastener appropriate for standard inch-series bolted joints requiring Grade 5 tensile strength.

Compatibility

Designed as an OEM-style and maintenance replacement hex head cap screw for standard inch-series bolted assemblies requiring a 1-1/4-7 UNC thread and 3-1/2 inch grip length.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with torque requirements for Grade 5 fasteners of this diameter. Always ensure mating threads are clean and free of debris before installation. Use the correct size hex socket or wrench to avoid rounding the head. Consult applicable equipment manufacturer specifications or industry fastener standards for proper torque values and joint design requirements.
