Value Collection 131199PR Set Screw 1/2-13 X 1 in Oval Point

Product Description

The VALUE COLLECTION 131199PR is a Grade 8 alloy steel set screw designed for secure, fastener-free clamping in mechanical assemblies. The oval point tip seats into a mating surface without the risk of shaft damage associated with cup or cone points, making it a practical choice for precision setups. It accepts a 1/4-inch hex key drive and meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians use this fastener in shaft collars, hubs, pulleys, and similar rotating or stationary component assemblies.

This set screw is suited for industrial, commercial, and heavy equipment maintenance applications where Grade 8 alloy steel strength is required. The 1/2-13 UNC thread pitch and 1-inch overall length make it appropriate for medium-to-heavy shaft and hub clamping tasks. It is sized for applications calling out ASME/ANSI B18.3 hex socket set screws and is sold in individual units with a minimum order quantity of 10.

Key Features

• Oval point geometry reduces shaft marring compared to cup or cone point styles
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 1/4-inch hex key drive for standard L-key or T-handle tooling
• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 1-inch overall length suits medium-depth hub and collar engagements

Compatibility

Designed as an OEM-style or maintenance replacement set screw for applications requiring a 1/2-13 UNC, 1-inch overall length, oval point, hex socket fastener conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/4-inch hex key or socket driver. De-energize and lock out all rotating equipment before servicing shaft assemblies. Apply thread-locking compound or verify torque requirements per the equipment manufacturer's specifications before tightening. Do not substitute a smaller hex key, as rounding the socket will require extraction.
