Bowmalloy 36054 Hex Head Cap Screw 3/8-16 X 1 in Grade 9

Product Description

The BOWMALLOY 36054 is a Grade 9 alloy steel hex head cap screw in a 3/8-16 thread size with a 1-inch length under head. Fully threaded and finished with a zinc-plated clear chromate coating, this fastener delivers high-strength clamping force with corrosion resistance suited for demanding mechanical and structural applications. The Grade 9 designation indicates superior tensile strength compared to Grade 5 and Grade 8 hardware, making it a reliable choice where load-bearing joints require tight tolerances and consistent performance. Licensed mechanics, millwrights, HVAC technicians, and general contractors commonly specify this fastener type for heavy-duty assemblies.

This hex head cap screw is suited for use in industrial machinery, mechanical equipment frames, HVAC unit mounting, and structural fastening applications where an inch-series, fully threaded fastener is required. The 3/8-16 coarse thread pattern engages quickly and holds well in steel and cast components. The clear chromate zinc finish provides a layer of corrosion protection appropriate for indoor and sheltered outdoor environments. Sold in packages of 100, this fastener is well matched for production assembly, service fleets, and maintenance shops that keep common hardware sizes in bulk stock.

Key Features

• Grade 9 alloy steel construction for high tensile strength beyond standard Grade 8 hardware
• Fully threaded body maximizes thread engagement across the full 1-inch length under head
• 3/8-16 UNC coarse thread compatible with standard inch-series nuts and tapped holes
• Zinc-plated clear chromate finish provides corrosion resistance in sheltered environments
• Hex drive head accepts standard 9/16-inch wrenches and sockets for fast installation
• Package quantity of 100 suits bulk restocking and production assembly workflows

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 3/8-16 x 1-inch fully threaded hex head cap screw in Grade 9 alloy steel with a zinc clear chromate finish.

Installation Notes

This fastener is installed by mechanics, millwrights, HVAC technicians, and maintenance professionals using standard hand tools or impact drivers with a 9/16-inch socket. Always inspect mating threads and tapped holes for damage or contamination before installation. Verify that the joint material and application load requirements are compatible with Grade 9 alloy steel hardware before substituting for a lower-grade fastener. Follow applicable industry torque standards for 3/8-16 hardware based on joint design and lubrication conditions.
