Value Collection KP44003 Hex Head Cap Screw 1/4-20 X 1-1/4 in

Product Description

The VALUE COLLECTION KP44003 is a 1/4-20 UNC hex head cap screw manufactured from Grade 8 steel with a zinc-plated finish. The fastener measures 1-1/4 inches under the head and features partial threading along the shank. Grade 8 steel delivers high tensile strength suited to heavy-duty mechanical and structural applications. The zinc coating provides a baseline level of corrosion resistance for general indoor and light outdoor use. This screw meets ASTM A354 BD standards, making it a specification-grade fastener appropriate for assemblies where material certification is required. Sold in a package of 100 units per order.

This fastener is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical panel mounting, plumbing fixture installation, and general mechanical fabrication. The 1/4-20 UNC thread is one of the most common inch-series thread sizes in North American trade work, making this screw compatible with a broad range of tapped holes, nuts, and threaded inserts already in use in the field. The partial threading design allows the unthreaded shank to bear shear loads more effectively than a fully threaded fastener of the same length.

Key Features

• Grade 8 steel construction rated to high tensile and proof load requirements
• 1/4-20 UNC thread form matches the most widely used inch-series coarse thread standard
• Partial threading provides improved shear strength at the shank
• Zinc-plated finish for baseline corrosion resistance
• Meets ASTM A354 BD specification for material traceability and certification
• Packaged in quantities of 100 for shop stock or job-site use

Compatibility

Designed for use with standard 1/4-20 UNC tapped holes, hex nuts, and threaded inserts in inch-series fastener applications across mechanical, electrical, and HVAC assemblies.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 1/4-20 hex head fastener. De-energize and lock out any equipment before fastener installation or removal in electrical or mechanical enclosures, following applicable NFPA 70E and OSHA lockout-tagout procedures. Do not over-torque Grade 8 fasteners in soft or tapped aluminum base materials, as thread stripping can occur. Verify the receiving thread standard matches UNC before installation.
