Bowmalloy BOWMP36306 Hex Head Cap Screw 1/4-28 X 1-1/2 in

Product Description

The BOWMALLOY BOWMP36306 is a Grade 9 steel hex head cap screw with a 1/4-28 thread size and a 1-1/2 inch length under head. It features partial threading and a Bowma-Guard protective finish. Grade 9 steel delivers high tensile strength suitable for demanding fastening applications. The Bowma-Guard finish provides corrosion resistance to extend service life in exposed or harsh environments. This screw is sold in a package quantity of 50 and is well suited for mechanical assemblies, equipment fabrication, and structural fastening work where a high-strength inch-series fastener is required.

This hex head cap screw is used across a wide range of industrial and trade applications, including HVAC equipment assembly, mechanical systems, structural brackets, and general equipment maintenance. The 1/4-28 fine-thread specification makes it appropriate for applications requiring precise thread engagement and strong clamping force. Partial threading allows for a grip length that provides secure clamping between joined materials without thread engagement through the full shank.

Installation Notes

Installation should be performed with the appropriate hex socket or open-end wrench sized for the fastener head. Ensure mating threads are clean and free of debris before driving the screw. Follow applicable torque specifications for Grade 9 fasteners as defined by your project or equipment manufacturer guidelines. Always de-energize or depressurize any system before replacing or adding fasteners to mechanical assemblies.
