Product Description

The VALUE COLLECTION KP44004 is a 1/4-20 x 1-1/2 inch hex head cap screw manufactured from Grade 8 steel with a zinc-plated finish. It features partial threading and conforms to ASTM A354 BD standards, making it suitable for high-strength fastening applications. The 1/4-20 UNC thread pattern provides reliable engagement in standard inch-system assemblies. This fastener is sold in a package of 100 pieces, making it appropriate for contractors, maintenance technicians, and tradespeople who need a reliable supply of high-strength hardware on the job.

This cap screw is used across a wide range of trade applications including HVAC equipment mounting, electrical panel and enclosure assembly, plumbing fixture support, and general mechanical fastening where high-tensile hardware is required. The zinc plating provides corrosion resistance suitable for indoor and light-exposure environments. The partial threading is appropriate for applications requiring a bearing surface against the fastened material, such as clamping two components together with a defined grip length.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with fastener torque specifications appropriate to Grade 8 hardware and the specific joint design. Use a properly sized hex wrench or socket driver to avoid rounding the head. Ensure mating threads in the tapped hole or nut are clean and free of debris before installation. Do not substitute a lower-grade fastener in applications where Grade 8 strength is specified.
