Value Collection 131185PR Set Screw 3/8-24 X 1/2 in Oval Point

Product Description

The VALUE COLLECTION 131185PR is a 3/8-24 UNF alloy steel set screw with an oval point, rated Grade 8 for high-strength fastening applications. Measuring 1/2 inch in overall length, it is driven by a 3/16 inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. The oval point geometry provides a low-marring contact against the mating surface while still delivering reliable holding force under load. This fastener is suited for mechanical assemblies, shaft collars, couplings, and similar applications where a flush or recessed fastener is required. Installation is performed by machinists, maintenance technicians, and assembly workers using standard hex key tooling.

The 131185PR set screw is used in industrial and mechanical assembly environments where a threaded fastening element must be seated below the surface of a component. Typical applications include locking hubs, gears, pulleys, and collars onto shafts in light to heavy-duty machinery. The oval point contacts the shaft at a small curved tip, reducing surface damage compared to cup or cone point designs while still resisting rotation and axial movement under vibration or moderate torque loads.

Key Features

• 3/8-24 UNF thread for fine-pitch engagement and precise adjustability
• Oval point reduces surface marring on mating shafts compared to flat or cup point styles
• Grade 8 alloy steel provides high tensile and torsional strength
• 3/16 inch hex drive compatible with standard hex keys and L-wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• 1/2 inch overall length suits shallow-engagement fastening requirements

Compatibility

Designed as a standard 3/8-24 UNF set screw for use in any threaded bore or collar manufactured to ASME/ANSI B18.3 specifications requiring an oval point, Grade 8 alloy steel fastener.

Installation Notes

Install using a properly sized 3/16 inch hex key to avoid rounding the drive socket. Ensure the receiving threaded bore is clean and free of debris before threading in the screw. De-energize and lock out any rotating equipment before installing or adjusting set screws on live shafts. Follow applicable machine safety and torque guidelines per the equipment manufacturer's specifications.
