Value Collection 101283PR Set Screw 10-32 5/8in Cup Point

Product Description

The VALUE COLLECTION 101283PR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and hardness suitable for demanding industrial and commercial applications. The cup point digs into the mating surface to resist rotation and axial movement without the need for a protruding head. Drive is a 3/32-inch hex socket, driven with a standard hex key or Allen wrench. The thread is 10-32 UNF with an overall length of 5/8 inches, conforming to ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is used wherever a flush or recessed fastener is required to lock a shaft, collar, pulley, gear, or similar component in place. Typical applications include HVAC blower wheel shaft collars, motor shaft collars, shaft couplings, and general mechanical assemblies across residential and commercial equipment. It is installed by machinists, millwrights, HVAC technicians, and maintenance professionals. Minimum order quantity is 100 pieces per order; package quantity is 1.

Key Features

• Cup point geometry bites into shaft surface to resist rotation and axial movement
• Grade 8 alloy steel construction provides high hardness and tensile strength
• 10-32 UNF thread for precise fit in standard tapped holes
• 3/32-inch hex drive compatible with standard hex keys
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• No protruding head — flush or recessed seating in the tapped hole

Compatibility

Designed as a standard 10-32 UNF cup point set screw for use in any tapped hole conforming to 10-32 UNF thread specifications per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 3/32-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Always de-energize and lock out equipment before accessing shaft assemblies or mechanical components. Do not exceed the rated capacity of the tapped hole material when tightening. Follow applicable machinery safety standards and equipment manufacturer guidelines during installation.
