Value Collection 101193PR Set Screw 8-32 Cup Point Grade 8

Product Description

The VALUE COLLECTION 101193PR is a headless set screw designed for mechanical fastening applications where a flush or recessed installation is required. It features an 8-32 UNC thread and measures 0.125 inches in overall length. The cup point geometry bites into mating surfaces to resist rotation and axial movement without requiring a through-hole. Driven by a 5/64-inch hex key, this fastener is made from alloy steel at Grade 8, providing high tensile strength relative to its size. It meets ASME/ANSI B18.3 and ASTM F912 standards. Licensed machinists, millwrights, and maintenance technicians are the typical installers.

This set screw is suited for light-duty shaft-to-hub connections, collar positioning, and component locking in machinery, motors, and assemblies found in both residential and commercial equipment. The 8-32 UNC thread size is common in small mechanical assemblies, including HVAC blower wheel hubs, motor shaft collars, and similar applications. Sold individually per package with a minimum order quantity of 100 pieces, making it appropriate for maintenance stock or production use.

Key Features

• Cup point tip grips mating shaft surface to resist rotation and axial displacement
• 8-32 UNC thread for compatibility with standard inch-series tapped holes
• Grade 8 alloy steel construction provides high shear and tensile strength in a small form factor
• 5/64-inch hex drive for use with standard Allen-type keys
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• 0.125-inch overall length suits shallow-threaded collar and hub applications

Compatibility

Designed as a standard inch-series set screw for use in any application with an 8-32 UNC tapped hole requiring a cup point, headless fastener per ASME/ANSI B18.3.

Installation Notes

Installation requires a 5/64-inch hex key; confirm the tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before servicing shaft collars or rotating components. Do not over-torque: Grade 8 alloy steel set screws at this size are rated for specific torque ranges per published fastener standards — consult those references before applying final torque. Follow applicable mechanical codes and equipment manufacturer service documentation.
