Bowmalloy 36086 Hex Head Cap Screw 7/16-14 X 2-3/4 in Grade 9

Product Description

The BOWMALLOY 36086 is a Grade 9 alloy steel hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. It features a 7/16-14 unified coarse thread with a 2-3/4 inch length under the head and is partially threaded for positive grip in through-bolt and bolted-joint applications. The clear zinc chromate finish provides corrosion resistance suitable for general industrial environments. This fastener is installed by mechanical contractors, millwrights, equipment technicians, and maintenance professionals working with standard SAE-pattern hardware.

This hex head cap screw is used across a broad range of trade and industrial applications including HVAC equipment mounting, plumbing skid fabrication, electrical enclosure assembly, and general mechanical equipment installation. The Grade 9 rating indicates a minimum tensile strength above standard Grade 5 and Grade 8 classifications, making it appropriate for high-load bolted connections where a coarse 7/16-14 thread pattern is specified. It follows inch-series dimensional standards and is compatible with standard 7/16-14 hex nuts and flat washers.

Key Features

• Grade 9 alloy steel construction for elevated tensile strength in demanding bolted joints
• 7/16-14 unified coarse thread for reliable engagement with standard inch-series hardware
• Partially threaded shank provides a smooth bearing surface for shear-load and alignment applications
• Clear zinc chromate finish offers corrosion resistance in general industrial service environments
• Hex head drive accepts standard open-end, box-end, and socket wrenches

Compatibility

Designed for use with standard 7/16-14 inch-series hex nuts, lock nuts, and flat washers in mechanical and structural fastening applications.

Installation Notes

Install using a standard 5/8-inch hex wrench, socket, or impact driver with the appropriate drive size. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for Grade 9 fasteners. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
