Value Collection 403020PR 1/4-20 X 1-1/4 in Hex Cap Screw

Product Description

The VALUE COLLECTION 403020PR is a 1/4-20 hex head cap screw designed for general-purpose fastening in a wide range of trade and industrial applications. This partially threaded fastener measures 1-1/4 inches under the head and is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. The UNC thread standard ensures compatibility with standard inch-series tapped holes and nuts. Installation requires a 7/16-inch hex wrench or socket. This screw is a workhorse fastener suited for light structural and mechanical assemblies where high-strength alloy grades are not required.

This cap screw is commonly used in residential and light commercial construction, HVAC equipment assembly, electrical enclosure mounting, plumbing fixture attachment, and general mechanical fabrication. The partial thread shank allows for clamping of multiple workpiece layers and is appropriate in applications where a smooth shank section improves joint integrity. Licensed tradespeople and maintenance technicians alike use this fastener for routine equipment installation and field repairs.

Key Features

• 1/4-20 UNC thread size for compatibility with standard inch-series hardware
• 1-1/4 inches length under head for medium-depth fastening applications
• Partially threaded shank for improved clamping in multi-layer assemblies
• Grade 2 steel construction suited for general-purpose, non-high-stress use
• Zinc-plated finish provides basic corrosion resistance in dry to mildly humid environments
• 7/16-inch hex drive for use with standard wrenches and sockets

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/4-20 UNC tapped hole, nut, or threaded insert in general mechanical and structural applications.

Installation Notes

Installation is performed with a 7/16-inch open-end, box, or socket wrench. Ensure the mating tapped hole or nut is clean and free of debris before fastening. Do not exceed the load limits appropriate for Grade 2 steel in structural or safety-critical connections — consult applicable building or mechanical codes where required. Power down or de-energize any equipment before fastening screws near live electrical components.
