Bowmalloy 36110 Hex Head Cap Screw 1/2-13 X 2.5 in Grade 9

Product Description

The BOWMALLOY 36110 is a Grade 9 alloy steel hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Measuring 1/2-13 thread size with a 2.5-inch length under head, this cap screw is partially threaded and finished with a clear zinc chromate coating for corrosion resistance. Grade 9 alloy steel exceeds the tensile strength of Grade 8, making it suitable for demanding load-bearing connections. It is installed by millwrights, maintenance technicians, and mechanical contractors working on heavy equipment, machinery mounts, and structural joints.

This cap screw is well suited for use in industrial maintenance, OEM equipment assembly, and field repair scenarios where high-strength inch-series fasteners are required. The 1/2-13 unified coarse thread pattern is widely used across North American equipment platforms. The clear zinc chromate finish provides a base level of corrosion protection appropriate for indoor and sheltered outdoor installations.

Key Features

• Grade 9 alloy steel construction for elevated tensile and proof load strength beyond Grade 8
• 1/2-13 unified coarse thread, partially threaded shank
• 2.5-inch length under head for deep fastening applications
• Clear zinc chromate finish for corrosion resistance
• Inch measurement system for compatibility with standard SAE tooling

Compatibility

Designed as an OEM-style and aftermarket replacement hex head cap screw for industrial and mechanical assemblies requiring 1/2-13 inch-series fasteners with Grade 9 alloy steel specifications.

Installation Notes

Installation is performed by qualified millwrights, maintenance technicians, or mechanical contractors. Always power down and de-energize or de-pressurize the associated equipment before fastener removal or installation. Use a calibrated torque wrench and follow the equipment manufacturer's torque specifications for the applicable joint. Fasteners should be inspected for thread condition and replaced if any deformation or corrosion is present.
