Value Collection 403272BR Hex Head Cap Screw 3/4-10

Product Description

The VALUE COLLECTION 403272BR is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and industrial applications. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener features a 3/4-10 UNC thread and measures 2-1/2 inches under the head. It conforms to ASME B18.2.1, ASTM A307, and SAE J429 standards, making it a reliable choice for light to moderate load applications. Installation requires a 1-1/8 inch hex wrench or socket. Weighing approximately 0.39 pounds per unit, it is suited for use in fabrication, maintenance, and general mechanical assembly work.

This cap screw is a standard inch-system fastener used across residential and commercial construction, HVAC equipment assembly, plumbing support structures, and general mechanical applications. Fully threaded along its 2-1/2 inch shank, it provides consistent thread engagement across the full length of the fastener, which is particularly useful in through-bolt and short-stack joint configurations. Trades including HVAC technicians, plumbers, electricians, and mechanical contractors routinely stock this size for equipment mounting and structural support work.

Compatibility

Designed as a standard inch-system hex head cap screw suitable for general mechanical and structural fastening applications where a 3/4-10 UNC fully threaded fastener is specified.

Installation Notes

Installation should be performed by qualified tradespeople using a properly sized 1-1/8 inch socket or wrench. Always de-energize or depressurize associated equipment before fastening or removing hardware in mechanical systems. Do not overtighten beyond the torque limits specified by the joint design or equipment manufacturer. Fasteners used in structural or pressure-bearing applications should be selected and torqued in accordance with applicable codes and engineering specifications.
