Value Collection 111179PR Set Screw 10-24 5/16 in Grade 8

Product Description

The VALUE COLLECTION 111179PR is a 10-24 UNC alloy steel set screw with a knurled cup point and a 3/32-inch hex drive. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, this Grade 8 fastener delivers high hardness and strong holding power without a protruding head. The knurled cup point bites into mating surfaces to resist rotational and axial movement under vibration and load. It is installed using a 3/32-inch hex key and is suited for mechanical assemblies, shaft collars, and equipment where flush or recessed clamping is required. Machinists, millwrights, and maintenance technicians are the primary installers.

This set screw is used in light mechanical assemblies, HVAC equipment, motors, and industrial machinery where a headless fastener is specified. The 10-24 thread size and 5/16-inch overall length make it a common choice for shaft collar and hub applications in both commercial and light industrial settings. Sold individually per package; minimum order quantity is 100 pieces.

Key Features

• Grade 8 alloy steel construction for high hardness and clamping strength
• Knurled cup point grips mating surfaces to resist vibration-induced loosening
• Headless design sits flush with or below the surface of the work piece
• 3/32-inch hex drive accepts standard hex keys and T-handle drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• UNC 10-24 thread form for broad compatibility with standard tapped holes

Compatibility

Designed for use in standard 10-24 UNC tapped holes requiring a headless set screw with a knurled cup point, as specified by ASME/ANSI B18.3.

Installation Notes

Installation requires a 3/32-inch hex key; torque to the assembly specification provided by the equipment manufacturer. Ensure the mating shaft or surface is clean and free of burrs before seating the cup point. Follow applicable ANSI and equipment OEM guidelines for fastener installation in rotating or load-bearing assemblies. Do not reuse set screws that show deformation at the point or drive socket.
