Value Collection 101113P Set Screw 5-40 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101113P is a cup point set screw designed for secure, permanent-to-semi-permanent fastening applications where a headless profile is required. Sized at 5-40 UNC thread by 1/4 inch overall length, this screw is manufactured from Grade 8 alloy steel for high tensile strength and resistance to shear forces. A 1/16 inch hex drive accepts a standard hex key for installation into blind holes and threaded bores. The cup point geometry bites into mating surfaces to resist rotation and axial movement. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for precision applications.

Cup point set screws in the 5-40 thread size are widely used in light mechanical assemblies, shaft collars, pulleys, knobs, and small gear hubs across industrial, HVAC, and electrical equipment. The headless design allows full thread engagement flush with or below the surface of the receiving component, making this screw suitable for rotating assemblies and tight clearance installations. This SKU is sold individually but requires a minimum order quantity of 100 pieces.

Key Features

• 5-40 UNC thread form compatible with standard tapped holes in that size
• 1/4 inch overall length for shallow-bore fastening applications
• Cup point geometry creates positive bite on mating shaft or surface
• 1/16 inch hex drive for use with standard hex keys or L-wrenches
• Grade 8 alloy steel construction for high tensile and shear strength
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards

Compatibility

Designed as a standard headless cup point set screw for any threaded bore or shaft collar tapped to 5-40 UNC specifications.

Installation Notes

Installation is performed with a 1/16 inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Verify the receiving thread is clean and free of debris before engagement. In rotating or vibrating assemblies, consider a thread-locking compound appropriate for the application. Always follow applicable mechanical assembly codes and equipment manufacturer guidelines when specifying fastener substitutions.
