Value Collection KP44077 Hex Head Cap Screw 1/2-13 X 1-1/4 in Grade 8

Product Description

The VALUE COLLECTION KP44077 is a 1/2-13 x 1-1/4 inch fully threaded hex head cap screw manufactured from Grade 8 steel with a zinc-plated finish. Grade 8 is among the highest strength classifications for inch-series fasteners, making this screw suited for high-load structural and mechanical connections. The zinc plating provides a baseline level of corrosion resistance for general indoor and light outdoor applications. Sold in a package of 50, this screw meets ASTM A354 BD standards and follows Unified National Coarse thread form, offering reliable thread engagement in standard tapped holes and nuts.

This cap screw is used across a broad range of industrial, mechanical, and trade applications where high-tensile fasteners are required. Common install scenarios include equipment mounting, bracket fabrication, structural assemblies, and HVAC or mechanical room equipment installations. The fully threaded shank allows engagement along the entire length under the head, which is useful in thin-material and close-tolerance assemblies. Electricians, pipefitters, HVAC mechanics, and general maintenance trades all encounter this fastener size in day-to-day service work.

Key Features

• Grade 8 steel construction for high-tensile strength in demanding mechanical applications
• Fully threaded along the 1-1/4 inch length under head for maximum thread engagement
• 1/2-13 UNC thread form compatible with standard inch-series nuts and tapped holes
• Zinc-plated finish for basic corrosion resistance
• Meets ASTM A354 BD standard for proof load and tensile strength requirements
• Sold in a quantity of 50 per package

Compatibility

Designed for use with standard 1/2-13 UNC inch-series hex nuts, flat washers, and lock washers in general mechanical and structural fastening applications.

Installation Notes

Installation should be performed by qualified tradespeople using the appropriate hex wrench or socket set sized for a 1/2 inch fastener. Always verify that mating threads and tapped holes conform to UNC specifications before installation. Torque to values appropriate for Grade 8 fasteners as specified by applicable engineering standards or equipment manufacturer documentation. Inspect threads for damage before use and do not force cross-threaded fasteners.
