Bowmalloy 36070 Hex Head Cap Screw 3/8-16 X 6 in Grade 9

Product Description

The BOWMALLOY 36070 is a Grade 9 alloy steel hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and trade service work. It features a 3/8-16 UNC thread with a 6-inch length under the head and is partially threaded, providing a strong grip shank for load-bearing connections. The zinc-plated clear chromate finish offers corrosion resistance suitable for general-purpose indoor and light outdoor use. This fastener is installed by HVAC technicians, plumbers, electricians, millwrights, and general contractors wherever a reliable, high-tensile hex cap screw is required.

This screw is suited for structural connections, equipment mounting, and mechanical assemblies that demand Grade 9 tensile strength. The 3/8-16 coarse thread is a common size across HVAC equipment frames, pump housings, electrical enclosures, and fabricated steel structures. The partial threading allows the unthreaded shank to align mating components cleanly before the threads engage, which is useful in heavy equipment and close-tolerance assemblies. Sold in packages of 25, this screw is appropriate for both single-unit service repairs and multi-unit installation projects.

Key Features

• Grade 9 alloy steel construction for high tensile and proof load strength
• 3/8-16 UNC coarse thread for wide compatibility with standard nuts and tapped holes
• 6-inch length under head accommodates thick assemblies and stacked materials
• Partially threaded shank provides a smooth bearing surface for load transfer and component alignment
• Zinc-plated clear chromate finish provides corrosion resistance for general-purpose applications
• Inch measurement system; UNSPSC code 31161501

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/8-16 UNC threaded nuts, inserts, and tapped holes in alloy steel, structural steel, and fabricated equipment assemblies.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 3/8-16 hex cap screw head. Always verify that mating threads are clean and free of debris before assembly. Power down or de-energize any equipment before accessing fastener locations on live electrical or mechanical systems. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for Grade 9 fasteners.
