Value Collection 131175PR Set Screw 3/8-16 X 5/8 in Oval Point

Product Description

The VALUE COLLECTION 131175PR is a 3/8-16 UNC set screw with an oval point, manufactured from Grade 8 alloy steel. Set screws of this type are headless fasteners used to secure a component — such as a pulley, gear, collar, or hub — against a shaft by applying internal clamping force. The oval point provides a low-stress contact that reduces shaft damage compared to cup or cone points, making it a common choice for softer shafts or applications where the fastener may need to be repositioned. It is driven with a 3/16-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is suited for mechanical assembly applications across industrial, HVAC equipment, and general trade use. Typical installations include shaft-to-hub connections on blower wheels, fan pulleys, motor couplings, and machine components where rotational load must be resisted without a traditional bolt head. The overall length of 5/8 inches accommodates standard shaft collar depths found in light to medium-duty mechanical assemblies. Sold individually with a minimum order quantity of 100 pieces, this fastener is intended for shop stock or job-lot procurement.

Key Features

• Oval point design reduces shaft damage and allows repositioning without significant marring
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 3/8-16 UNC thread for broad compatibility with standard inch-series tapped components
• Driven with a 3/16-inch hex key — no external wrench clearance required
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard UNC inch-series set screw for use in any tapped hole or threaded insert with 3/8-16 threads requiring an oval point headless fastener.

Installation Notes

Installation requires a 3/16-inch hex key or Allen driver; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Power down or de-energize any rotating equipment completely before accessing shaft collars or hub assemblies. Follow applicable machinery safety standards and lock-out/tag-out procedures before service. Do not exceed the torsional capacity of the alloy steel drive socket by using extension bars on the hex key.
