Value Collection 101401PR Set Screw 5/16-18 X 1-3/4 in Cup Point

Product Description

The VALUE COLLECTION 101401PR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Sized at 5/16-18 UNC thread with an overall length of 1-3/4 inches, it is driven with a 5/32-inch hex key. Manufactured from Grade 8 alloy steel, this set screw delivers high tensile strength suitable for demanding clamping and locking applications. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a reliable choice for maintenance, production, and repair work across industrial and mechanical trades.

Cup point set screws like the 101401PR are used wherever a shaft, rod, or component must be locked in position within a hub, collar, pulley, sprocket, or similar part. The cup point digs into the mating surface to resist axial and rotational movement, making it well suited for moderate to heavy-duty shaft locking on equipment and machinery. This screw is appropriate for both original equipment assembly and field maintenance applications handled by millwrights, machinists, and maintenance technicians.

Key Features

• 5/16-18 UNC thread for standard fractional inch compatibility
• 1-3/4-inch overall length for deep engagement in thick hubs or collars
• Cup point geometry bites into mating surfaces to resist slippage under load
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 5/32-inch hex drive accepts standard hex keys and L-wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as a standard 5/16-18 UNC cup point set screw for use in any hub, collar, or mechanical assembly requiring ASME/ANSI B18.3-compliant headless socket set screws.

Installation Notes

Installation is performed with a 5/32-inch hex key or L-wrench; ensure the key is fully seated before applying torque to avoid rounding the socket. De-energize or lock out all equipment before accessing rotating shafts or assemblies in accordance with applicable OSHA lockout/tagout procedures. Confirm that the mating bore and set screw threads are clean and free of debris before installation. Do not substitute a hex key of incorrect size, as this can strip the drive socket.
