Bowmalloy BOWMP36058 Hex Head Cap Screw 3/8-16 X 2 in

Product Description

The BOWMALLOY BOWMP36058 is a 3/8-16 partially threaded hex head cap screw measuring 2 inches in length under the head. Manufactured from Grade 9 steel and finished with Bowma-Guard coating, this fastener is built for high-strength structural and mechanical applications where resistance to corrosion and loosening under load are critical requirements. Grade 9 steel exceeds the tensile strength ratings of the more common Grade 5 and Grade 8 classifications, making it a preferred choice when joint integrity cannot be compromised. Licensed contractors, millwrights, maintenance technicians, and industrial assemblers typically specify this fastener for demanding bolted connections.

This cap screw is suited for heavy-duty mechanical assemblies, industrial equipment mounting, structural steel connections, and maintenance applications across manufacturing, construction, and utility sectors. The partial threading allows for a smooth shank bearing area under the head, which is preferred in applications where shear loads are present or where a close-tolerance fit through a clearance hole is required. Sold in packages of 25 units, making it practical for both single-job use and recurring maintenance stock.

Key Features

• Grade 9 steel construction for high tensile strength beyond standard Grade 5 and Grade 8 ratings
• Bowma-Guard finish provides corrosion resistance for extended service life
• Partial threading with smooth shank for applications with shear loading or close-tolerance clearance holes
• 3/8-16 unified coarse thread for broad compatibility with standard hex nuts and tapped holes
• 2-inch length under head suits medium-depth bolted joints in structural and mechanical assemblies
• Sold in packs of 25 for efficient stocking and job-site use

Compatibility

Designed for use with standard 3/8-16 unified coarse thread hex nuts, washers, and tapped components conforming to inch-series fastener standards.

Installation Notes

Installation should be performed by qualified mechanics, millwrights, or maintenance technicians familiar with torque requirements for Grade 9 fasteners. Always verify the mating thread size and tapped hole depth before installation to avoid cross-threading or bottoming out. Use a calibrated torque wrench and follow the applicable fastener torque specification for the joint design - do not estimate by feel on high-strength hardware. Inspect the Bowma-Guard finish for damage before installation; compromised coating may reduce corrosion resistance at the fastener head.
