Value Collection 101457P Set Screw 3/8-16 X 3/4 in Cup Point

Product Description

The VALUE COLLECTION 101457P is a cup point set screw designed for secure shaft-to-hub and collar retention applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and load. The 3/8-16 UNC thread size pairs with a 3/4-inch overall length, and the 3/16-inch hex drive accepts a standard hex key for installation in confined spaces. Licensed tradespeople and maintenance mechanics working on motors, pulleys, couplings, and similar rotating components will reach for this fastener regularly. It meets ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is suited for general industrial, HVAC mechanical, and facilities maintenance work where a cup point is needed to bite into a shaft and resist rotational movement. The cup point geometry concentrates clamping force at a small contact area, making it effective on both hardened and unhardened shafts. It is sold individually with a minimum order quantity of 100 pieces per order, making it appropriate for shop stock and bulk maintenance supply.

Key Features

• Cup point geometry bites into shaft surface for strong rotational hold
• Grade 8 alloy steel construction for high tensile and proof load strength
• 3/8-16 UNC thread standard for wide compatibility with standard tapped holes
• 3/16-inch hex drive fits standard hex keys and T-handle drivers
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Fractional inch sizing for use in imperial-dimensioned assemblies

Compatibility

Designed as a standard 3/8-16 UNC cup point set screw for use in any tapped hole conforming to ASME/ANSI B18.3 specifications, including shaft collars, shaft couplings, pulleys, sprockets, and similar mechanical components.

Installation Notes

Installation requires a 3/16-inch hex key or Allen-type driver. Ensure the mating shaft and tapped hole are clean and free of debris before driving the screw. Power down and de-energize any associated rotating equipment before servicing. Tighten to the assembly specification for the mating component; do not overtighten, as this can damage the shaft surface or strip the tapped hole.
