Bowmalloy 36145 Hex Head Cap Screw 5/8-11 X 1 in Grade 9

Product Description

The BOWMALLOY 36145 is a Grade 9 alloy steel hex head cap screw designed for high-strength fastening applications. It features a 5/8-11 thread size with a 1-inch length under the head and is fully threaded from tip to head. The clear zinc chromate finish provides corrosion resistance in demanding environments. This fastener is installed by mechanical contractors, millwrights, equipment technicians, and industrial maintenance professionals who require reliable, specification-grade hardware in structural and mechanical assemblies.

This screw is suited for industrial, commercial, and heavy equipment applications where Grade 9 alloy steel strength is specified. Fully threaded construction makes it appropriate for through-bolting into nuts or threaded plates. The zinc-plated clear chromate finish is compatible with both indoor and outdoor service conditions where moderate corrosion protection is required.

Key Features

• Grade 9 alloy steel construction for high tensile strength fastening requirements
• 5/8-11 thread size with 1-inch length under head in the inch measurement system
• Fully threaded shank for maximum thread engagement in through-bolt applications
• Clear zinc chromate finish provides corrosion resistance over bare steel
• Hex head drive compatible with standard wrenches and sockets

Compatibility

Designed as a Grade 9 alloy steel hex head cap screw for industrial and mechanical fastening applications requiring 5/8-11 inch-system thread specification.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel familiar with fastener torque specifications for Grade 9 hardware. Always consult the equipment manufacturer or applicable structural engineering specification for required torque values before installing. Inspect mating threads for damage or contamination before assembly. Do not substitute a lower-grade fastener where Grade 9 is specified.
