Value Collection 101483PR Set Screw 3/8-24 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION 101483PR is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping force without protruding above the surface. Manufactured from Grade 8 alloy steel, this screw provides high tensile strength and resistance to shear forces common in shaft-to-hub and collar applications. The 3/8-24 UNF thread pitch offers fine adjustment control, and the 5/8-inch overall length suits standard hub depths. Drive is a 3/16-inch internal hex, compatible with standard hex keys and Allen-type drivers. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards and is suited for use by machinists, maintenance technicians, and industrial assembly professionals.

This set screw is used in applications requiring secure locking of rotating components such as pulleys, sprockets, collars, and couplings onto shafts. The cup point geometry bites into the shaft surface to resist axial and rotational movement under load. It is appropriate for both light-duty and moderate-load industrial settings. The fine UNF thread series makes it a good fit where vibration resistance and precise positioning are priorities. Installation is typically performed during mechanical assembly or field service on rotating equipment.

Key Features

• Cup point tip bites into shaft surface for positive locking without added hardware
• Grade 8 alloy steel construction delivers high tensile and shear strength
• 3/8-24 UNF fine thread for precise adjustment and improved vibration resistance
• 3/16-inch internal hex drive compatible with standard hex keys
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits fully flush or recessed within tapped holes

Compatibility

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

Installation Notes

Installation is performed by machinists or maintenance technicians using a 3/16-inch hex key or Allen driver. De-energize and lock out all equipment before servicing rotating assemblies. Apply the fastener to a clean, dry, properly tapped hole and tighten to the torque value specified in the equipment manufacturer's documentation. Avoid overtightening, which can deform the cup point or strip the threaded bore.
