Value Collection 131079PR Set Screw 10-24 X 1/2 in Oval Point

Product Description

The VALUE COLLECTION 131079PR is a 10-24 x 1/2 inch oval point set screw manufactured from Grade 8 alloy steel. Set screws are headless fasteners that thread fully into a tapped hole to secure a component — such as a collar, hub, or pulley — against rotation or axial movement on a shaft. This screw uses a 3/32 inch hex drive and conforms to ASME/ANSI B18.3 and ASTM F912 standards. The oval point geometry provides a low-stress contact area that reduces damage to the mating shaft surface, making it well suited for semi-permanent assemblies where the fastener may need to be repositioned. Machinists, millwrights, and maintenance technicians are the primary installers.

This set screw is used in light to medium industrial and mechanical assemblies where a threaded 10-24 UNC hole is required. Typical applications include securing shaft collars, sprockets, gears, and couplings in HVAC equipment drives, pump assemblies, fan blade hubs, and general mechanical power transmission components. The oval point is preferred in applications where repeated adjustment is expected or where shaft marking must be minimized. Sold individually; minimum order quantity is 100 pieces.

Key Features

• Grade 8 alloy steel construction provides high tensile and torsional strength for demanding mechanical applications
• Oval point tip reduces stress concentration on the mating shaft surface compared to cup or cone point designs
• 3/32 inch hex drive accepts standard hex keys and hex bit drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 10-24 UNC thread standard ensures broad compatibility with inch-series tapped holes
• Headless design sits flush or below the surface of the receiving component

Compatibility

Designed for use in any assembly with a 10-24 UNC tapped through-hole or blind hole requiring an oval point set screw to ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed with a 3/32 inch hex key or T-handle hex driver. De-energize and lock out any equipment before installing or adjusting set screws in rotating assemblies. Do not overtighten — apply torque gradually and verify shaft or hub engagement before returning equipment to service. Thread engagement and torque requirements should follow the equipment manufacturer's fastener specifications for 10-24 Grade 8 fasteners.
