Value Collection 101445P Set Screw 3/8-16 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101445P is a Grade 8 alloy steel cup point set screw sized 3/8-16 x 1/4 inches overall length. Set screws are headless fasteners threaded along their full length and are driven with a hex key rather than a wrench or driver. This screw uses a 3/16-inch hex drive and terminates in a cup point, which bites into the mating surface to resist rotation and axial movement. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, it is suited for demanding mechanical assemblies where reliable holding force is required. Machinists, millwrights, and maintenance technicians install these in shaft collars, pulleys, sprockets, and similar components.

The 101445P is used in industrial, commercial, and light manufacturing applications where a flush or recessed fastener is needed to secure a rotating or stationary component to a shaft or housing. The cup point geometry provides a moderate bite into softer shaft materials without causing excessive damage, making it a common choice for shaft collar retention, set collar adjustments, and fixture work. This fastener follows UNC and UNF thread standards under the 3/8-16 designation. Minimum order quantity is 100 pieces per order, sold as individual units per package.

Key Features

• Cup point tip bites into mating surfaces to resist rotation and axial load
• Grade 8 alloy steel construction for high tensile and torsional strength
• 3/16-inch hex drive accepts standard hex keys and Allen wrenches
• Fully threaded headless design allows flush or below-surface installation
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• UNC thread standard for broad compatibility with inch-series tapped holes

Compatibility

Designed for use in 3/8-16 UNC tapped holes in shaft collars, hubs, pulleys, sprockets, and similar mechanical components requiring a headless cup point fastener per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 3/16-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Power down or de-energize any rotating equipment and lock out the shaft before installing or removing set screws. Verify the tapped hole is clean and free of debris to achieve full thread engagement. Minimum order quantity requirements apply — order in multiples of 100.
