Value Collection 101451PR Set Screw 3/8-16 X 7/16 in Cup Point

Product Description

The VALUE COLLECTION 101451PR is a 3/8-16 cup point set screw manufactured from Grade 8 alloy steel. It measures 7/16 inches in overall length with a 3/16-inch hex drive and a unified coarse (UNC) thread form. Set screws of this type are headless fasteners used to secure a component — such as a collar, gear, or pulley — against a shaft or mating surface. The cup point digs into the mating part to resist rotation and axial movement without requiring a nut. This fastener conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it suitable for applications where dimensional and mechanical consistency is required.

This set screw is used in mechanical assemblies across industrial, HVAC, plumbing, and equipment maintenance applications. Common install scenarios include securing shaft collars on fan assemblies, locking pulleys on motor shafts, and fixing adjustment components in mechanical linkages. The 3/8-16 UNC thread size is widely used in mid-load mechanical hardware applications. Installation requires a 3/16-inch hex key. Minimum order quantity is 100 pieces; each package contains 1 piece.

Key Features

• Cup point geometry bites into mating surfaces to resist both rotational and axial movement
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 3/8-16 UNC thread form for broad compatibility with standard tapped holes
• 3/16-inch hex drive accepts standard hex keys and Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Headless design eliminates protruding fastener heads in tight clearance applications

Compatibility

Designed as a standard UNC set screw for use in any tapped 3/8-16 hole requiring a cup point, headless fastener per ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Set screws are typically installed by maintenance technicians and millwrights using a 3/16-inch hex key or Allen wrench. De-energize and lock out any rotating equipment before installing or removing set screws on shafts or couplings. Do not exceed the torque rating of the tapped hole material, particularly when threading into aluminum or softer alloys. Ensure the mating shaft surface is clean and free of debris before seating the cup point.
