Value Collection 131119PR Set Screw 1/4-28 X 1/4 in Oval Point

Product Description

The VALUE COLLECTION 131119PR is a 1/4-28 UNF threaded set screw with an oval point, manufactured from Grade 8 alloy steel. Measuring 1/4 inch in overall length and driven by a 1/8-inch hex key, this fastener is built for secure, non-marring clamping applications where a flush or recessed installation is required. Grade 8 alloy steel construction delivers high tensile strength and resistance to loosening under vibration. The oval point contacts the mating surface at a single rounded tip, reducing damage to shafts and bores. This screw conforms to ASME/ANSI B18.3 and ASTM F912 standards. Minimum order quantity is 100 pieces.

This set screw is used in mechanical assemblies where a shaft, collar, pulley, gear, or similar component must be fixed to a mating part without a protruding head. Common installation scenarios include motor shafts, drive couplings, and positioning collars in industrial and OEM equipment. The oval point makes it well suited for hardened shafts where a flat or cup point would be inappropriate. Machinists, millwrights, and maintenance technicians working on rotating equipment are the primary installers of this fastener type.

Key Features

• 1/4-28 UNF thread for fine-thread engagement and vibration resistance
• Oval point reduces surface damage on mating shafts and bores
• Grade 8 alloy steel provides high tensile and torsional strength
• 1/8-inch hex drive compatible with standard hex keys and T-handles
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Fractional inch sizing for broad compatibility with standard mechanical assemblies

Compatibility

Designed as a standard 1/4-28 UNF oval-point set screw for use in any mechanical assembly requiring a 1/4-28 fine-thread headless fastener with a 1/8-inch hex drive.

Installation Notes

Installation is performed with a 1/8-inch hex key or Allen wrench; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out all rotating equipment before accessing any shaft or coupling being secured. Thread engagement and seating should be confirmed before returning equipment to service. Follow applicable machinery safety standards and facility lockout/tagout procedures during installation.
