Value Collection 011155P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011155P is a hex socket cap screw designed for precision fastening in mechanical assemblies, tooling fixtures, and structural applications. It features a 1/4-20 UNC thread and measures 1-1/4 inches in length under the head. The screw is driven by a 3/16 inch hex key and is manufactured from alloy steel with a black oxide finish for corrosion resistance and reduced light reflection. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and strength standards. Installation is performed by machinists, maintenance technicians, and mechanical contractors across a wide range of industrial and trade settings.

This fastener is suited for use in machine frames, equipment enclosures, jigs, and other applications requiring a recessed-drive cap screw. The 1/4-20 UNC coarse thread makes it compatible with standard tapped holes in steel, aluminum, and similar materials. The fully threaded shank provides consistent clamping force along the entire length. This screw is a common choice for general-purpose mechanical assembly in both light industrial and commercial maintenance environments.

Key Features

• 1/4-20 UNC coarse thread for compatibility with standard tapped holes
• 1-1/4 inch length under head, fully threaded for maximum thread engagement
• 3/16 inch hex drive for use with standard hex keys and Allen wrenches
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide coating provides moderate corrosion resistance and low-glare finish
• Meets ASME/ANSI B18.3 dimensional standards for socket cap screws

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw per ASME/ANSI B18.3, suitable for use in any application requiring a conforming socket head cap fastener of this thread size and length.

Installation Notes

This fastener is installed using a 3/16 inch hex key or Allen driver; ensure the driver is fully seated in the socket to avoid stripping. De-energize and lock out any equipment before fastener installation or removal on powered machinery. Verify that the mating tapped hole meets ASME/ANSI B18.3 thread standards and is free of debris before driving the screw. Do not exceed the rated torque range for 1/4-20 alloy steel fasteners as specified by the applicable engineering or maintenance standard for the assembly.
