Value Collection 131124PR Set Screw 5/16-18 X 1/4 in Oval Point

Product Description

The VALUE COLLECTION 131124PR is a 5/16-18 UNC set screw with an oval point, manufactured from Grade 8 alloy steel for high-strength fastening applications. At 1/4 inch in overall length, it is driven with a 5/32 inch hex key. The oval point design provides a self-centering contact with the mating surface, reducing surface damage compared to cup or flat point styles. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. It is installed by maintenance technicians and mechanical assemblers wherever a secure, tamper-resistant hold on shafts, collars, or set positions is required.

This set screw is suited for use in mechanical assemblies where a shaft, hub, or collar must be locked in a fixed position without a protruding fastener head. Typical applications include motor shafts, pulleys, gear hubs, and machinery collars in industrial, HVAC, and general mechanical maintenance settings. The Grade 8 alloy steel construction handles the torque and shear loads common in these installations. This item is sold individually but requires a minimum order quantity of 100 pieces.

Key Features

• Oval point tip self-centers on the mating surface and reduces surface marring compared to flat or cup points
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 5/16-18 UNC thread for broad compatibility with standard tapped holes
• 5/32 inch hex drive for use with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Compact 1/4 inch overall length suits tight-clearance assemblies

Compatibility

Designed as an OEM-style replacement or standard replacement fastener for any mechanical assembly that requires a 5/16-18 UNC set screw with an oval point and a 5/32 inch hex drive.

Installation Notes

Installation is typically performed by a maintenance technician or millwright using a 5/32 inch hex key or T-handle driver. Always de-energize and lockout/tagout any rotating equipment before accessing shaft or collar fasteners. Thread the set screw into the tapped hole by hand first to avoid cross-threading, then torque using the appropriate hex key. Do not reuse a set screw that shows deformation or thread damage.
