Value Collection 101067PR Set Screw 3-48 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101067PR is a cup point set screw designed for precise positioning and locking of components on shafts, collars, and assemblies. Manufactured from Grade 8 alloy steel, it delivers high tensile strength and resistance to shear forces under load. The screw measures 3-48 thread size by 1/4 inch overall length and is driven with a 0.050-inch hex key. Conforming to ASME/ANSI B18.3 and ASTM F912 standards, this fastener is suited for applications where a secure, headless profile is required. Machinists, millwrights, and maintenance technicians regularly specify this type of screw in precision mechanical assemblies.

This set screw is used in light-duty mechanical assemblies requiring a compact, flush-mounted fastener with a cup point that bites into the mating surface to resist rotation and axial movement. Typical applications include shaft collars, gear hubs, pulleys, and fixture components where a headless fastener profile is necessary. The UNC thread standard makes it compatible with standard inch-series tapped holes in production and MRO environments.

Key Features

• Cup point geometry bites into mating surface for positive rotational and axial holding force
• Grade 8 alloy steel construction for high tensile and shear strength
• Hex socket drive accepts a 0.050-inch hex key for installation in confined spaces
• Headless profile sits flush or below the surface to eliminate snag hazards
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• UNC thread standard for compatibility with standard inch-series tapped holes

Compatibility

Designed as an OEM-style replacement or standard MRO fastener for any application requiring a 3-48 UNC cup point set screw with a 0.050-inch hex drive in an inch-series tapped hole.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 0.050-inch hex key. Always ensure the mating tapped hole is clean and free of debris before threading the screw. De-energize or lock out any rotating equipment before installing or removing set screws on shaft-mounted components, per applicable LOTO procedures. Do not over-drive the screw, as the small thread size is susceptible to stripping under excessive torque.
