Value Collection 011157P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011157P is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies, fixtures, and equipment. It features a 1/4-20 UNC thread size with a 1-1/2 inch length under head and a 3/16 inch hex drive. Manufactured from alloy steel with a black oxide finish, it meets ASME/ANSI B18.3 and ASTM A574 standards. The partial threading allows for precise clamping force and is well suited to threaded metal applications where socket head access is needed. This screw is a standard choice in industrial, HVAC equipment, and mechanical service work.

This fastener is used in a wide range of trade and industrial applications including HVAC equipment assembly, electrical enclosure mounting, pump and motor hardware, and general mechanical repairs. The socket cap head design allows installation in confined spaces where a standard hex head wrench cannot reach. The black oxide coating provides mild corrosion resistance suitable for indoor and controlled environments. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped holes
• 1-1/2 inch length under head for moderate-depth fastening applications
• 3/16 inch hex socket drive for use with standard Allen or hex key tooling
• Partially threaded shank provides positive clamping and shoulder alignment
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish offers mild corrosion resistance and reduced surface glare

Compatibility

Designed as a standard inch-series socket cap screw for use in any application requiring a 1/4-20 UNC threaded socket head fastener conforming to ASME/ANSI B18.3.

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 driving the fastener. De-energize and lock out any equipment before replacing or tightening hardware in live assemblies. Do not exceed the rated torque specification for 1/4-20 ASTM A574 alloy steel fasteners as referenced in standard fastener engineering tables.
