Value Collection 011565BR Hex Socket Cap Screw 1-1/4-7 Unc

Product Description

The VALUE COLLECTION 011565BR 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-inch length under the head and is partially threaded. The drive is a 7/8-inch internal hex socket, requiring an appropriately sized hex key or Allen driver. Constructed from alloy steel with a black oxide coating, this screw delivers solid mechanical strength and moderate corrosion resistance in controlled environments. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for applications that demand verified fastener performance.

This cap screw is suited for use in machine assembly, equipment fabrication, jig and fixture construction, and general industrial fastening where a recessed-drive, high-strength fastener is required. The partial thread configuration allows for clamping force across unthreaded material, making it appropriate for bolted joints where the shank passes through a clearance hole before engaging the threaded section. Machinists, millwrights, maintenance technicians, and fabricators are the typical installers. It is sold individually.

Key Features

• 1-1/4-7 UNC thread size for coarse-thread engagement in heavy fastening applications
• 5-inch length under head with partial threading for clamped-joint installations
• 7/8-inch internal hex socket drive for high-torque installation with standard hex keys
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 and ASTM A574 compliant hex socket cap screw for use in any application requiring a 1-1/4-7 UNC partially threaded fastener with a 5-inch length under head.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or maintenance technician using a properly sized 7/8-inch hex key or socket driver. Verify thread engagement depth and ensure mating threads are clean and free of debris before installation. Always follow applicable torque specifications from the equipment manufacturer or relevant ASME standards. Inspect the fastener and mating components for damage before installation and do not reuse fasteners that show signs of thread deformation.
