Value Collection 101562P Set Screw 1/2-13 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION 101562P is a 1/2-13 UNC cup point set screw designed for clamping and positioning applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to shear forces, making it suitable for securing shafts, collars, pulleys, and similar components. The 1/4-inch hex drive accepts a standard hex key for installation and removal. Overall length is 3/8 inches. This screw meets ASME/ANSI B18.3 and ASTM F912 standards. It is installed by machinists, millwrights, and maintenance technicians across industrial and commercial applications.

This set screw is suited for use in shaft-to-hub connections where a headless fastener is required to sit flush or below the surface of the mating part. The cup point geometry bites into the shaft to resist rotation and axial movement under load. Typical applications include motor shafts, gear hubs, shaft collars, conveyor components, and HVAC blower wheel assemblies. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• Cup point geometry grips shaft surfaces to resist rotation and axial shift
• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• 1/4-inch hex drive accepts standard hex keys
• Headless design allows installation flush with or below component surface
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw for use in any tapped hole conforming to ASME/ANSI B18.3 specifications. Suitable for shaft collars, pulleys, gears, and other mechanical components requiring a headless clamping fastener.

Installation Notes

Installation is performed with a 1/4-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive. De-energize and lock out any rotating equipment before servicing components secured by set screws. Inspect the mating shaft for damage or contamination before threading the fastener. Apply thread-locking compound where vibration may loosen the screw over time.
