Value Collection 131163PR Set Screw 3/8-16 X 3/8 Oval Point

Product Description

The VALUE COLLECTION 131163PR is a 3/8-16 UNC set screw with an oval point, manufactured from Grade 8 alloy steel for high-strength clamping and locking applications. Measuring 3/8 inches in overall length, it is driven by a 3/16-inch hex key. The oval point geometry provides a low-stress contact profile on mating shaft surfaces, reducing indentation compared to cup or cone point designs. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance. It is suitable for use in mechanical assemblies, power transmission components, and industrial equipment where a reliable, flush-seating set screw is required.

This set screw is used in applications where a shaft, collar, gear, pulley, or hub must be secured against rotation or axial movement without a protruding fastener head. The oval point is particularly suited for installations where the mating shaft must be removable without permanent damage to the surface. Typical installers include millwrights, maintenance technicians, and mechanical assemblers working on rotating equipment, conveyor systems, and drive train components. The UNC thread form ensures compatibility with standard inch-series tapped holes.

Key Features

• Grade 8 alloy steel construction provides high tensile and torsional strength
• Oval point reduces surface damage on mating shaft during tightening and removal
• 3/16-inch hex drive accepts standard Allen or hex key tooling
• UNC thread standard ensures compatibility with common inch-series tapped bores
• Meets ASME/ANSI B18.3 and ASTM F912 for dimensional and mechanical conformance

Compatibility

Designed as a standard UNC inch-series set screw for use in any 3/8-16 tapped hole requiring an oval point, headless fastener in mechanical or industrial assemblies.

Installation Notes

Installation requires a 3/16-inch hex key or Allen wrench. De-energize and lock out all rotating or powered equipment before installing or adjusting set screws. Ensure the tapped hole is clean and free of debris before threading to avoid cross-threading or stripping. Do not exceed the torque capacity of the alloy steel fastener by using impact tools or extension bars on the hex key.
