Value Collection R40311122 Set Screw 1-72 X 3/16 in Cup Point

Product Description

The VALUE COLLECTION R40311122 is a 1-72 x 3/16-inch cup point set screw manufactured from Grade 18-8 stainless steel. Set screws are headless fasteners used to secure a component — such as a gear, pulley, or collar — onto a shaft by applying direct pressure through the point contact. The cup point geometry bites into the mating surface to resist rotation and axial movement. The hex drive socket accepts a 0.0350-inch hex key for installation in tight clearance applications. This fastener is sold individually with a minimum order quantity of 100 pieces.

This set screw is suited for light-duty mechanical assemblies, instrumentation, and precision equipment where a small-diameter, fine-thread fastener is required. The 1-72 UNF thread standard makes it appropriate for applications demanding close thread engagement in thin or delicate materials. Grade 18-8 stainless steel provides corrosion resistance for use in humid or mildly corrosive environments. Machinists, maintenance technicians, and assembly professionals working with small-scale mechanical components are the typical installers.

Key Features

• Cup point tip bites into shaft or mating surface to resist slippage under load
• Grade 18-8 stainless steel construction resists corrosion in wet or outdoor-exposed assemblies
• 1-72 UNF fine thread for maximum engagement in thin material cross-sections
• 0.0350-inch hex drive accepts standard hex keys for installation in confined spaces
• Headless design sits flush or below surface, keeping clearance profiles minimal
• Overall length of 3/16 inches suits shallow-depth collar and hub applications

Compatibility

Designed as a standard 1-72 UNF replacement or new-install set screw for mechanical assemblies requiring a headless cup point fastener in Grade 18-8 stainless steel.

Installation Notes

Installation requires a 0.0350-inch hex key; confirm key fit before applying torque to avoid socket rounding on this small-diameter fastener. Ensure the mating shaft or component is clean and properly positioned before driving the screw to its seating depth. Follow applicable mechanical assembly standards and avoid overtightening, which can strip the fine 1-72 UNF thread or deform the cup point. Minimum order quantity is 100 pieces per order.
