Value Collection 101475PR Set Screw 3/8-24 X 5/16 in Cup Point

Product Description

The VALUE COLLECTION 101475PR is a 3/8-24 hex socket cup point set screw designed for secure shaft-to-hub and collar retention applications. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength suitable for demanding mechanical assemblies. The 5/16-inch overall length and 3/16-inch hex drive make it appropriate for compact installation spaces. The cup point tip bites into the mating surface to resist rotational and axial movement without requiring a through-hole. Licensed technicians, millwrights, and mechanical installers working with rotating components, shafts, and precision assemblies will encounter this fastener class regularly in their work.

This set screw is used in industrial and commercial mechanical assemblies where shaft collars, pulleys, gears, and hubs must be positionally fixed to a shaft. The 3/8-24 UNF thread pitch provides fine thread engagement for applications requiring precise depth adjustment and resistance to loosening under vibration. It is also used in HVAC blower wheel hubs, motor shaft collars, and general mechanical drive components where a clean exterior profile is required. Minimum order quantity is 100 pieces per order, with individual package quantity of 1.

Key Features

• Grade 8 alloy steel construction provides high tensile and proof load strength
• Cup point tip digs into mating surface for strong rotational and axial holding force
• 3/8-24 UNF fine thread for precise depth setting and vibration resistance
• 3/16-inch hex socket drive accepts standard hex keys and hex bit drivers
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical compliance
• Fully threaded, headless design sits flush or below surface for clean assembly profiles

Compatibility

Designed as a standard UNF set screw for use in any 3/8-24 threaded hole requiring a cup point, headless hex socket fastener per ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Install using a 3/16-inch hex key or hex bit driver. Ensure the threaded hole is clean and free of debris before seating the screw. Tighten to the point of firm resistance against the shaft or mating surface without exceeding the fastener or assembly manufacturer specifications. Always de-energize and lock out rotating machinery before adjusting or replacing set screws on live shafts or drive components.
