Value Collection 011569BR Hex Socket Cap Screw 1-1/4-7 Unc

Product Description

The VALUE COLLECTION 011569BR is a heavy-duty hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, structural connections, and industrial equipment. The screw features a 1-1/4-7 UNC thread size with 6 inches of length under the head and a 7/8-inch hex drive socket. Constructed from alloy steel with a black oxide coating, it delivers solid corrosion resistance and surface hardness suitable for demanding service environments. Partial threading allows for precise clamping force across joined materials. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards.

This cap screw is suited for use in heavy industrial machinery, structural steel fabrication, tooling fixtures, and OEM equipment assembly. Its large diameter and coarse UNC thread pitch make it a practical choice where high clamp load and vibration resistance are required. Machinists, millwrights, and maintenance technicians commonly install this fastener in both new construction and field repair scenarios.

Key Features

• 1-1/4-7 UNC coarse thread for high clamp load and vibration resistance
• 6 inches length under head with partial threading for precise joint clamping
• 7/8-inch hex socket drive for use with standard Allen keys or hex bit sockets
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide coating provides mild corrosion resistance and reduces light glare on exposed hardware
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard UNC hex socket cap screw for use in any application requiring a 1-1/4-7 thread form per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 7/8-inch hex key or hex socket bit with an appropriate torque wrench. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before performing fastener service on live machinery. Do not exceed the rated tensile strength of the fastener when applying torque.
