Bowmalloy 36053 Hex Head Cap Screw 3/8-16 X 7/8 in Grade 9

Product Description

The BOWMALLOY 36053 is a fully threaded hex head cap screw manufactured from Grade 9 alloy steel with a zinc-plated clear chromate finish. It is sized at 3/8-16 thread by 7/8 inches under the head, placing it in a range commonly specified for structural and mechanical fastening applications. The Grade 9 designation indicates a high-strength alloy construction suitable for demanding load and vibration conditions. The clear chromate zinc plating provides corrosion resistance appropriate for indoor and moderate-exposure environments. Licensed tradespeople and maintenance technicians working in mechanical, HVAC, or industrial service applications will find this screw sized and rated for typical equipment assembly and repair work.

This fastener is used wherever a high-strength inch-series hex head cap screw is called for in mechanical assemblies, equipment mounting, structural bracketing, and general industrial or trade applications. The 3/8-16 thread size is one of the most common coarse-thread inch-series fasteners in HVAC equipment, electrical enclosures, and mechanical systems. It is sold in packages of 100, making it practical for technicians who need a reliable job-site supply on hand.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 3/8-16 hex head cap screw. Always de-energize and lock out any equipment before fastening or removing hardware on live systems. Torque to values specified in the equipment manufacturer documentation or applicable mechanical standards - do not over-torque alloy steel fasteners into soft or cast components. Inspect threads for damage before installation to ensure proper seating and clamping force.
