Value Collection 121169PR Set Screw 3/8-16 X 1/2 in Cone Point

Product Description

The VALUE COLLECTION 121169PR is a 3/8-16 cone 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 against a shaft or mating surface. The cone point tip bites into the mating surface for a strong, vibration-resistant hold. This fastener uses a 3/16 inch hex key drive and measures 1/2 inch in overall length. It meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians install these in mechanical assemblies where a flush or recessed fastener is required.

This set screw is suited for general industrial and mechanical applications including shaft collars, shaft couplings, pulleys, gears, and similar rotating components. The cone point geometry is preferred when a permanent or semi-permanent installation is acceptable, as the tip cold-works into the shaft surface for maximum axial and torsional holding strength. The UNC thread standard makes it compatible with standard inch-series tapped holes common in North American industrial equipment.

Key Features

• Cone point tip provides high holding force by embedding into the mating shaft surface
• Grade 8 alloy steel construction for high tensile and torsional strength
• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes
• 3/16 inch hex key drive for precise torque application in tight clearances
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below the workpiece surface

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes in shaft collars, couplings, pulleys, gears, and similar mechanical assemblies requiring a cone point set screw.

Installation Notes

Installation is performed with a 3/16 inch hex key or Allen driver. De-energize and lock out all equipment before installing or adjusting set screws on rotating shafts. Ensure the tapped hole is clean and free of debris before threading the fastener in. Do not exceed the torque rating of the fastener or the tapped hole material, and verify thread engagement depth meets applicable design requirements.
