Bowmalloy BOWMP36129 Hex Head Cap Screw 9/16-12 X 1 in

Product Description

The BOWMALLOY BOWMP36129 is a fully threaded hex head cap screw designed for high-strength bolted assemblies in industrial and commercial applications. Built to Grade 9 steel specifications, this fastener delivers superior tensile strength compared to standard Grade 5 or Grade 8 hardware. The Bowma-Guard finish provides corrosion resistance for use in demanding environments. With a 9/16-12 thread size and a 1 inch length under head, it suits structural connections, heavy equipment, and fabrication work where precise torque loading and thread engagement are critical.

This cap screw is intended for use in heavy-duty mechanical and structural assemblies across industrial, agricultural, and construction applications. The 9/16-12 UNC thread pattern is a common size in North American inch-standard fastener systems, making it a straightforward replacement or maintenance fastener for existing bolted joints. It is sold in packages of 5 units and is well-suited for maintenance crews, millwrights, and fabricators working on high-load connections requiring Grade 9 performance.

Compatibility

Designed as an OEM-style replacement or maintenance fastener for Grade 9 inch-series bolted assemblies using 9/16-12 UNC thread specifications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with inch-series fastener torque requirements for Grade 9 hardware. Always clean and inspect mating threads before installation. Follow applicable torque specifications from the equipment manufacturer or a recognized fastener standard such as those published by ASME or SAE. Do not substitute a lower-grade fastener in an application that specifies Grade 9.
