Value Collection 011147P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011147P is a hex socket cap screw designed for secure, high-torque fastening in industrial and mechanical assemblies. Built from alloy steel with a black oxide finish, this fastener resists corrosion and reduces light reflection in finished assemblies. It features a 1/4-20 UNC thread with a 5/8 inch length under head and is fully threaded, making it suitable for applications where maximum thread engagement is required. The 3/16 inch hex drive accepts standard Allen keys and hex-bit drivers. Licensed tradespeople, machinists, and maintenance technicians use this fastener type across a wide range of structural and equipment assemblies.

This fastener is suited for light to medium-duty mechanical assemblies in manufacturing, maintenance, and equipment fabrication environments. Its fully threaded 1/4-20 UNC configuration is common in HVAC equipment panels, electrical enclosures, pump housings, and general industrial hardware applications where a recessed drive head is preferred to minimize profile. The black oxide coating provides a uniform, low-glare appearance often specified in OEM equipment builds.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• Fully threaded along the 5/8 inch length under head for maximum thread engagement
• 3/16 inch hex socket drive accepts standard Allen keys and hex-bit drivers
• Alloy steel construction provides higher tensile strength than standard steel fasteners
• Black oxide coating reduces surface corrosion and light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard UNC hex socket cap screw for use in any 1/4-20 tapped hole requiring a recessed hex drive fastener conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation requires a 3/16 inch hex key or Allen-bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or thread-locking compound per the equipment manufacturer's requirements. Never exceed the rated drive torque for the fastener size, and inspect threads for damage before installation.
