Bowmalloy 36087 Hex Head Cap Screw 7/16-14 X 3 in Grade 9

Product Description

The BOWMALLOY 36087 is a Grade 9 alloy steel hex head cap screw sized 7/16-14 x 3 inches with a zinc-plated clear chromate finish. Grade 9 fasteners deliver higher proof load and tensile strength than the more common Grade 5 or Grade 8 hardware, making this screw a sound choice for high-stress mechanical and structural assemblies. The partial threading design allows the unthreaded shank to bear shear loads cleanly, a critical factor in bolted joints subject to lateral forces. This screw ships in a package quantity of 25, with a minimum order quantity of 1. Tradespeople, maintenance technicians, and OEM assemblers working in HVAC, mechanical, and industrial applications will find this fastener suited to demanding service conditions.

This cap screw is appropriate for use in residential and commercial mechanical assemblies where high-strength inch-series fasteners are required. Typical applications include equipment mounting, structural bracketing, and machinery assembly wherever a 7/16-14 thread pattern and 3-inch grip length are specified. The clear chromate zinc plating provides a baseline level of corrosion resistance suitable for indoor and light-duty outdoor installations.

Key Features

• Grade 9 alloy steel construction for elevated tensile and proof load strength
• 7/16-14 UNC thread form in standard inch measurement system
• 3-inch length under head with partial threading to support shear-load applications
• Zinc-plated clear chromate finish for corrosion protection
• Packaged in quantities of 25 per pack

Compatibility

Designed as a standard inch-series hex head cap screw for use in any assembly specifying a 7/16-14 thread size and 3-inch length under head in Grade 9 alloy steel.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with proper fastener torque procedures for Grade 9 hardware. Always de-energize or shut down the equipment being serviced before replacing or installing fasteners in mechanical assemblies. Use a calibrated torque wrench and consult the equipment manufacturer's torque specification table for the correct value at this thread size and grade. Do not substitute lower-grade fasteners in applications where Grade 9 is specified.
