Value Collection 111163PR Set Screw 8-32 X 5/8 in Alloy Steel

Product Description

The VALUE COLLECTION 111163PR is an 8-32 x 5/8 inch knurled cup point set screw manufactured from Grade 8 alloy steel. Set screws of this type are headless fasteners that thread fully into a tapped hole to lock a component — such as a collar, gear, or pulley — against a shaft. The knurled cup point bites into the mating surface for enhanced grip and resistance to loosening under vibration. Drive is a 5/64 inch hex (Allen) socket. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for industrial and trade applications.

This set screw is used in mechanical assemblies across HVAC equipment, electrical panels, pump assemblies, and general industrial installations. Typical applications include securing shaft collars, sprockets, and hubs where a flush or recessed fastener is required. The 8-32 UNC thread is a common size encountered in light-duty mechanical components across residential and commercial equipment. Installation is performed by maintenance technicians, millwrights, and trade mechanics using standard hex key tooling.

Key Features

• Knurled cup point provides increased holding force against shaft surfaces compared to a plain cup point
• Grade 8 alloy steel construction for high tensile and torsional strength
• 8-32 UNC thread standard for broad compatibility with tapped holes in light mechanical assemblies
• 5/64 inch hex drive accepts standard Allen wrenches and hex key sets
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Overall length of 5/8 inches suits moderate engagement depth requirements

Compatibility

Designed as a standard 8-32 UNC set screw for use in any tapped hole conforming to ASME/ANSI B18.3 specifications for socket set screws in that thread size.

Installation Notes

Installation requires a 5/64 inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Verify the mating tapped hole is clean and free of debris before threading in the fastener. De-energize and lock out any equipment before accessing rotating assemblies or shaft components. Minimum order quantity for this part is 100 pieces per order.
