Value Collection KP44010 Hex Head Cap Screw 1/4-20 X 3 in Grade 8

Product Description

The VALUE COLLECTION KP44010 is a 1/4-20 x 3-inch hex head cap screw designed for high-strength fastening applications across industrial, mechanical, and trade installations. Manufactured from Grade 8 steel with a zinc-plated finish, this screw meets ASTM A354 BD standards for tensile strength and dimensional consistency. The partially threaded shank provides a bearing surface that resists joint loosening under vibration and dynamic load. The UNC (Unified National Coarse) thread form ensures broad compatibility with standard tapped holes and nuts. Sold in a pack of 50, this fastener is well suited for volume repair and assembly work where consistent, code-grade hardware is required.

This hex head cap screw is appropriate for structural and mechanical assemblies in residential and light commercial settings, including equipment mounting, bracket fabrication, ductwork support framing, and general trade work. The Grade 8 rating makes it suitable where higher shear and tensile strength are required compared to common Grade 2 or Grade 5 hardware. The zinc plating provides basic corrosion resistance for indoor and semi-protected outdoor use. Licensed tradespeople across HVAC, plumbing, and electrical disciplines routinely stock this fastener size for field repairs and panel assembly.

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw for use in any application requiring a Grade 8 partially threaded fastener at 3 inches length under head.

Installation Notes

Installation should be performed by a qualified tradesperson using an appropriately sized hex wrench or socket driver. Always verify that the mating tapped hole or nut matches the 1/4-20 UNC thread specification before installation. De-energize or shut down any equipment being serviced before fastener work begins. Do not exceed the rated tensile or shear capacity of this fastener by substituting it in applications requiring a higher grade without engineering review.
