Value Collection 011161P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011161P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 1/4-20 UNC thread size with a 2-inch length under the head and is partially threaded. The screw is driven with a 3/16-inch hex key. Constructed from alloy steel and finished with a black oxide coating, it provides good tensile strength and moderate corrosion resistance. This fastener meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards. Installation is handled by machinists, maintenance technicians, and mechanical contractors.

This screw is suited for use in machine frames, jigs, dies, and general industrial assemblies where a flush or recessed fastener head is required. The partial threading allows the unthreaded shank to align components accurately before the threaded section engages. It is appropriate for both light manufacturing and heavy industrial environments. The black oxide finish helps reduce light reflection and provides mild protection in dry or lightly oiled conditions.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 2-inch length under head with partial threading for shank-guided alignment
• 3/16-inch hex drive for use with standard Allen wrenches and hex keys
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide coating provides mild corrosion resistance and low-glare finish
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard replacement or stocking fastener for any application requiring a 1/4-20 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Install using a 3/16-inch hex key or Allen driver; ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. Do not overtighten — follow the torque guidelines specified in your engineering drawings or assembly documentation. Alloy steel fasteners used in structural applications may be subject to applicable ASME or industrial standards for the specific assembly.
