Value Collection KP44076 1/2-13 X 1 in Grade 8 Hex Cap Screw 50pk

Product Description

The VALUE COLLECTION KP44076 is a Grade 8 hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and trade service work. Measuring 1/2-13 thread size with a 1-inch length under head and fully threaded shank, this screw meets ASTM A354 BD standards, indicating high tensile and proof load strength. The zinc-plated finish provides baseline corrosion resistance in dry and mildly humid environments. The Unified National Coarse (UNC) thread form ensures broad compatibility with standard tapped holes and nuts. This fastener is sold in a package quantity of 50, making it suitable for production runs and service calls where multiple fasteners are needed.

This cap screw is used across a wide range of trade applications including HVAC equipment mounting, plumbing fixture support structures, electrical enclosure assembly, and general mechanical fabrication. The Grade 8 rating makes it appropriate for joints that require higher clamping force than standard Grade 5 or Grade 2 hardware. It is installed by mechanics, millwrights, HVAC technicians, and general tradespeople wherever a high-strength inch-series hex fastener is required. The fully threaded shank is particularly useful in shorter bolt lengths where maximum thread engagement is needed through thin material or into a nut.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile strength requirements
• Fully threaded shank provides maximum thread engagement across the full 1-inch length
• 1/2-13 UNC thread form fits standard inch-series nuts, washers, and tapped holes
• Zinc-plated finish offers corrosion resistance in dry and low-moisture environments
• Package quantity of 50 supports production assembly and multi-fastener service jobs

Compatibility

Designed for use with standard 1/2-13 UNC nuts, flat washers, and lock washers in inch-series fastener applications. Compatible with any tapped or through-hole joint requiring a 1/2-13 thread pitch and Grade 8 strength rating.

Installation Notes

Install using a 3/4-inch hex wrench or socket driver. Power down and de-energize any equipment before accessing fastened assemblies in electrical or HVAC applications. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts, as mismatched grades can result in thread stripping under torque. Follow applicable codes and equipment manufacturer torque specifications for the joint being serviced.
