Value Collection 011167P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011167P is a partially threaded hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. It features a 1/4-20 UNC thread size and a 2-3/4 inch length under head, making it suitable for applications requiring a strong, recessed-drive connection. The 3/16 inch hex drive accepts a standard hex key or Allen driver. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength along with basic corrosion resistance. It meets ASME/ANSI B18.3 and ASTM A574 standards. Licensed tradespeople and assembly technicians rely on this style of cap screw across a wide range of maintenance and fabrication tasks.

This socket cap screw is suited for residential and commercial mechanical installations, equipment manufacturing, and general industrial assembly. It is commonly used where a low-profile, high-strength fastener with a recessed drive is required in confined or tight-clearance spaces. The partial threading engages the mating surface without threading the full shank, which is useful in clamping applications where joint compression is needed. Electricians, HVAC technicians, plumbers, and millwrights frequently use socket cap screws of this type when assembling equipment panels, brackets, and structural components.

Key Features

• 1/4-20 UNC thread for reliable engagement in standard tapped holes
• 2-3/4 inch length under head suits moderate-depth fastening applications
• Partially threaded shank provides effective clamping in bolted joint assemblies
• 3/16 inch hex drive accepts standard hex keys and Allen drivers
• Alloy steel construction for high tensile and yield strength
• Black oxide finish offers surface protection and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard 1/4-20 UNC partially threaded hex socket cap screw for use in any application requiring an ASME/ANSI B18.3 and ASTM A574 compliant alloy steel fastener in that thread size and length.

Installation Notes

Install using a 3/16 inch hex key or ball-end Allen driver; ensure the mating hole is properly tapped to 1/4-20 UNC before installation. De-energize all equipment and follow applicable lockout/tagout procedures before accessing any panel or assembly where this fastener is used. Do not exceed the rated torque range for 1/4-20 alloy steel fasteners as specified by the equipment manufacturer or applicable standards. Inspect threads for damage before installation and replace any fastener that shows signs of stripping or deformation.
