Value Collection MP30055 Hex Cap Screw 3/8-16 X 1-1/4 in Grade 5

Product Description

The VALUE COLLECTION MP30055 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener meets UNC thread standards and provides reliable clamping force in a wide range of assembly and maintenance tasks. The 3/8-16 thread size and 1-1/4-inch length under head make it a commonly specified size across HVAC, plumbing, and equipment installation work. The zinc plating provides basic corrosion resistance suitable for indoor and protected outdoor environments. Each package contains 25 screws.

This hex head cap screw is suited for light to medium-duty fastening in equipment panels, brackets, frames, and mechanical assemblies. It is commonly used by HVAC technicians, plumbers, electricians, and general maintenance trades wherever a standard UNC-threaded fastener is required. The fully threaded shank allows for consistent thread engagement across the full length of the fastener, making it appropriate for thinner materials and through-bolted connections.

Installation Notes

Installation requires a standard hex wrench or socket driver sized for a 3/8-inch hex head cap screw. Always de-energize and lock out equipment before fastening or removing hardware on electrical or mechanical assemblies. Do not exceed the rated torque range for Grade 5 hardware as specified in the relevant equipment service documentation. Use appropriate thread lubricant or thread-locking compound as called out by the equipment manufacturer.
