Bowmalloy 36088 Hex Head Cap Screw 7/16-14 X 3-1/4 in Grade 9

Product Description

The BOWMALLOY 36088 is a Grade 9 alloy steel hex head cap screw sized at 7/16-14 thread x 3-1/4 inches under the head. Grade 9 alloy steel delivers higher tensile strength than Grade 5 or Grade 8 fasteners, making this screw well suited to high-stress mechanical and structural connections. The clear zinc chromate finish provides corrosion resistance in moderately demanding environments. The screw is partially threaded, which allows for better shear load transfer through the unthreaded shank section. Licensed trades and maintenance professionals use this fastener in equipment assemblies, brackets, and structural connections where elevated mechanical performance is required.

This hex head cap screw is used across a wide range of trade and industrial applications including HVAC equipment mounting, mechanical equipment frames, electrical enclosure hardware, and general structural assembly work. The 7/16-14 coarse thread pattern and partial threading make it a common choice when fastening through thicker steel members or into tapped holes where controlled thread engagement is important. It is sold individually with a package quantity of 25 pieces.

Key Features

• Grade 9 alloy steel construction for high tensile strength applications
• 7/16-14 UNC coarse thread for reliable engagement in steel and heavy materials
• 3-1/4 inch length under head with partial threading for shear load capacity
• Clear zinc chromate finish for moderate corrosion resistance
• Inch measurement system for compatibility with standard SAE tooling

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 7/16-14 x 3-1/4 inch Grade 9 alloy steel fastener with a clear zinc chromate finish.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional using a properly sized hex socket or open-end wrench. Always confirm that the mating tapped hole or nut thread specification matches 7/16-14 UNC before installation. De-energize and lock out any equipment before fastening or removing hardware on electrical or mechanical assemblies per applicable safety standards.
