Value Collection 151302PR Set Screw 5/16-24 X 3/8 in Flat Point

Product Description

The VALUE COLLECTION 151302PR is a Grade 8 alloy steel set screw with a flat point, designed for secure fastening applications where a flush or non-marring contact point is required. It carries a 5/16-24 UNF thread and measures 3/8 inches in overall length. Driven by a 5/32-inch hex key, this fastener meets ASME/ANSI B18.3 and ASTM F912 standards. Grade 8 alloy steel construction provides high tensile strength suitable for demanding mechanical assemblies. Machinists, millwrights, and maintenance technicians install these set screws in shaft collars, pulleys, gears, and similar components.

This set screw is suited for industrial, mechanical, and HVAC equipment assembly applications where a flat point contact is needed to avoid shaft damage or to bear against a flat. The flat point distributes clamping load across a surface rather than biting into it, making it appropriate for use on hardened shafts or in applications requiring occasional repositioning. Sold in packages of one, with a minimum order quantity of 100 units.

Key Features

• 5/16-24 UNF thread for precise, fine-pitch engagement
• 3/8-inch overall length in a compact, low-profile form factor
• Flat point design prevents shaft marring and allows surface-bearing load distribution
• Grade 8 alloy steel for high tensile and proof-load strength
• 5/32-inch hex drive compatible with standard Allen/hex key tools
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard UNF set screw for use in shaft collars, couplings, pulleys, gears, and mechanical assemblies that require a 5/16-24 threaded socket with flat point contact.

Installation Notes

Installation is performed using a 5/32-inch hex key torqued by hand or with a calibrated hex driver. De-energize and lock out any equipment before servicing fasteners on rotating components. Do not overtighten, as excessive torque can strip the socket or damage the mating threads. Ensure mating threaded holes are clean and free of debris before installation.
