Value Collection 011567BR Hex Socket Cap Screw 1-1/4-7 Unc

Product Description

The VALUE COLLECTION 011567BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1-1/4-7 UNC thread size with a 5-1/2 inch length under head and is partially threaded, providing clamping strength where full thread engagement is not required. Manufactured from alloy steel with a black oxide coating, this fastener offers corrosion resistance and a consistent finish suited to demanding service environments. The 7/8 inch hex drive accepts standard Allen-style socket tools. This screw meets ASME/ANSI B18.3 and ASTM A574 standards and is installed by millwrights, maintenance mechanics, and general contractors working on machinery and structural connections.

This hex socket cap screw is suited for use in industrial equipment, machinery frames, structural steel connections, and heavy-duty mechanical assemblies requiring a partially threaded alloy fastener. The black oxide finish makes it appropriate for applications where mild corrosion resistance and low-reflectivity appearance are functional requirements. It is sold as an individual unit and is compatible with standard UNC tapped holes of 1-1/4-7 thread specification.

Key Features

• 1-1/4-7 UNC thread size for use in standard coarse-thread tapped holes
• 5-1/2 inch length under head with partial threading for controlled clamp load
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide coating provides mild corrosion resistance and low-glare finish
• 7/8 inch hex socket drive for use with standard Allen wrenches or socket drivers
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed for use in any application requiring a 1-1/4-7 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench with a 7/8 inch hex bit. Verify that the mating tapped hole meets 1-1/4-7 UNC thread specifications before installation. Ensure the fastener threads and seating surface are clean and free of debris prior to assembly. Do not exceed the rated torque specification for the fastener grade and do not use impact tools that may damage the socket drive recess.
