Value Collection 111100PR Set Screw 6-32 3/8 in Grade 8

Product Description

The VALUE COLLECTION 111100PR is a 6-32 x 3/8-inch knurled cup point set screw manufactured from Grade 8 alloy steel. Set screws are headless fasteners that seat flush with or below a surface, used to secure a component — such as a collar, pulley, or gear — onto a shaft. The knurled cup point provides strong grip by biting into the mating surface, reducing slippage under vibration or torque. Drive is a 1/16-inch hex (Allen) socket. This fastener conforms to ASME/ANSI B18.3 and ASTM F912 standards and is appropriate for mechanical assemblies, HVAC equipment, and general industrial applications.

This set screw is suited for residential and light commercial mechanical assemblies where a compact, recessed fastener is required. Common applications include securing motor shaft collars, fan hubs, and adjustment mechanisms found in HVAC equipment, pumps, and rotating machinery. The 6-32 UNC thread is a fine-pitch coarse standard widely used in smaller mechanical components. Installation is performed by machinists, millwrights, HVAC technicians, and maintenance professionals. Minimum order quantity is 100 pieces; package quantity is 1.

Key Features

• Knurled cup point bites into shaft surface to resist rotation and axial movement
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 6-32 UNC thread standard ensures broad compatibility with standard tapped holes
• 1/16-inch hex drive accepts standard Allen/hex key tooling
• Headless design seats flush or below the work surface for clearance-critical assemblies
• Manufactured to ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed for use in any threaded 6-32 UNC tapped hole requiring a knurled cup point set screw with a 1/16-inch hex drive, consistent with ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation is performed with a 1/16-inch hex key; ensure the key is fully seated in the socket before applying torque to avoid rounding the drive. Power down and de-energize any equipment before servicing fasteners on rotating components. Do not overtighten — cup point set screws can permanently deform soft shaft materials. Follow applicable machinery safety standards and equipment manufacturer guidelines during reassembly.
