Bowmalloy 36058 Hex Head Cap Screw 3/8-16 X 2 in Grade 9

Product Description

The BOWMALLOY 36058 is a Grade 9 alloy steel hex head cap screw with a 3/8-16 thread size and a 2-inch length under head. It carries a zinc-plated clear chromate finish that provides corrosion resistance in demanding environments. The screw is partially threaded, which is standard for structural and mechanical fastening applications where clamping force and shear strength are critical. Licensed tradespeople and maintenance technicians in HVAC, mechanical, and industrial service work routinely specify Grade 9 fasteners where high-tensile strength is required beyond what Grade 5 or Grade 8 hardware can deliver.

This cap screw is suited for heavy-duty mechanical assemblies, equipment mounting, and structural connections in both commercial and industrial settings. The 3/8-16 coarse thread pattern engages quickly and holds well in steel and cast components. Partially threaded shanks make these fasteners appropriate for through-bolt applications and joints where the unthreaded shank bears shear loads. Sold in a package quantity of 50 units, this item is well-suited for service shops, contractors, and maintenance crews that work through fastener inventory regularly.

Key Features

• Grade 9 alloy steel construction for high tensile strength exceeding standard Grade 8 requirements
• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 2-inch length under head accommodates typical through-bolt and flange-mount applications
• Partially threaded shank distributes shear loads across the unthreaded body
• Zinc-plated clear chromate finish provides baseline corrosion protection in indoor and light outdoor use
• Package quantity of 50 units supports bulk service and stocking needs

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 3/8-16 UNC tapped holes, nuts, and threaded inserts in steel, cast iron, and aluminum assemblies across HVAC, mechanical, and industrial equipment applications.

Installation Notes

Installation is performed with a standard hex wrench or socket drive sized for a 3/8-16 hex head cap screw. Always de-energize and lock out equipment before fastener replacement on mechanical assemblies. Follow applicable equipment manufacturer torque guidelines and relevant codes such as ASME or equipment-specific service manuals. Do not reuse fasteners that show thread damage, corrosion, or deformation.
