Bowmalloy BOWMP36012 Hex Head Cap Screw 1/4-20 X 3 in

Product Description

The BOWMALLOY BOWMP36012 is a Grade 9 steel hex head cap screw with a 1/4-20 thread size and a 3-inch length under the head. It features a Bowma-Guard finish for corrosion resistance and is partially threaded, making it suited for clamping applications where the unthreaded shank provides shear strength across the joint. This fastener is installed by licensed tradespeople and maintenance professionals in mechanical, HVAC, plumbing, and structural assembly applications where a high-strength inch-series hex fastener is required.

This screw is appropriate for use in both commercial and industrial settings where Grade 9 tensile strength is specified. The partial threading design is commonly selected for through-bolt connections and flange assemblies where thread engagement is needed only at the nut end. The Bowma-Guard finish provides an additional layer of protection against oxidation in moderate-exposure environments. Sold in packages of 25 units with a minimum order quantity of 1 package.

Key Features

• Grade 9 steel construction for high tensile and proof-load strength
• 1/4-20 UNC thread size in the inch measurement system
• 3-inch length under head for deeper clamping reach
• Partially threaded shank for improved shear resistance in bolted joints
• Bowma-Guard finish for corrosion protection in moderate-exposure conditions
• Sold in convenient 25-piece packages

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/4-20 UNC threaded hole or nut where a Grade 9 fastener and partial threading are specified.

Installation Notes

Installation should be performed by qualified tradespeople following applicable mechanical and structural codes. Always confirm the mating thread specification matches 1/4-20 UNC before installation. Use a calibrated torque wrench when a torque specification is provided by the equipment manufacturer. Ensure the joint surfaces are clean and free of debris before fastening to achieve proper clamp load.
