Bowmalloy BOWMP36056 Hex Head Cap Screw 3/8-16 Grade 9

Product Description

The BOWMALLOY BOWMP36056 is a Grade 9 steel hex head cap screw designed for high-strength fastening in demanding mechanical and structural applications. Measuring 3/8-16 thread size with a 1-1/2 inch length under the head, it features partial threading and a Bowma-Guard finish that provides corrosion resistance in harsh service environments. Grade 9 fasteners exceed the strength requirements of Grade 8, making this screw appropriate for heavy-duty assemblies where fastener integrity under sustained load is critical. Installation requires a standard hex wrench or socket. This screw is sold in packages of 25 units with a minimum order quantity of 1 package.

This cap screw is suited for industrial, agricultural, heavy equipment, and structural fastening applications where high-strength inch-series hardware is specified. The 3/8-16 coarse thread and partial threading pattern allow efficient engagement in thick material joints and threaded plate assemblies. The Bowma-Guard finish makes it appropriate for environments with exposure to moisture, chemicals, or outdoor conditions. Mechanical contractors, millwrights, and maintenance technicians working on fabricated steel structures or heavy machinery will find this fastener a direct fit for Grade 9 specifications.

Compatibility

Designed for use in inch-series fastening applications specifying 3/8-16 Grade 9 hex head cap screws. Consult your equipment service manual to confirm fastener grade, thread pitch, and length requirements before installation.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with high-strength fastener procedures. Always verify thread engagement depth and ensure mating threads are clean and free of debris before driving the screw. Apply torque per the equipment manufacturer's specification for 3/8-16 Grade 9 fasteners using a calibrated torque wrench. Do not substitute a lower-grade fastener in a Grade 9-specified joint.
