Value Collection 101455PR Set Screw 3/8-16 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION 101455PR is a Grade 8 alloy steel set screw designed for secure, torque-resistant fastening in mechanical assemblies. This fully threaded fastener features a 3/8-16 UNC thread and measures 5/8 inches in overall length. The cup point geometry bites into the mating surface to resist rotational and axial movement without requiring a through-hole. Drive is a 3/16-inch hex (Allen) socket. It meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for precision industrial and mechanical applications where dimensional and strength compliance matter. Licensed tradespeople and mechanical contractors use these in shaft-to-hub connections, collars, and similar assemblies.

This set screw is used wherever a headless fastener is needed to lock a shaft, collar, gear, pulley, or hub in position. The cup point is the most common point style for general-purpose clamping because it creates a small indentation in softer shaft materials, providing positive retention. Typical applications include HVAC blower wheel hubs, motor shaft collars, pump couplings, and industrial mechanical assemblies requiring UNC-threaded Grade 8 fasteners. Sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point geometry provides positive bite into shaft or mating surface
• 3/16-inch hex (Allen) drive for access in tight or recessed locations
• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Fully threaded, headless design allows flush or below-surface installation

Compatibility

Designed as a standard UNC-thread set screw for use in any tapped 3/8-16 hole requiring a headless cup-point fastener to Grade 8 alloy steel specification per ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen wrench. Disengage power and lock out all energy sources before servicing any assembly that contains rotating shafts or components. Do not exceed the rated torque range for the thread size and grade as specified in applicable mechanical standards. Ensure the tapped hole is clean and the thread engagement depth is sufficient before applying final torque.
