Value Collection R40324460 Set Screw 1/4-20 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION R40324460 is a 1/4-20 UNC cup point set screw manufactured from grade 18-8 stainless steel. Set screws are fully threaded fasteners with no head that seat flush or below the surface of a workpiece, using internal torque applied through a hex key drive. The cup point bites into the mating surface to resist rotation and axial movement. At 5/8 inches in overall length with a 1/8-inch hex drive, this fastener is suited for light- to medium-duty clamping and locking applications across mechanical assemblies. It is installed by maintenance technicians, machinists, and field service professionals.

This set screw is used wherever a headless, flush-mount locking fastener is required, including shaft collars, pulleys, knobs, and mechanical linkages. Grade 18-8 stainless steel provides good corrosion resistance, making it appropriate for indoor and moderately corrosive environments. The cup point geometry concentrates clamping force at the contact area, providing reliable grip on both hardened and softer shaft materials. This item is sold individually but requires a minimum order quantity of 100 units per order.

Key Features

• Cup point geometry concentrates clamping force for reliable shaft or surface grip
• Grade 18-8 stainless steel construction provides corrosion resistance in moderate environments
• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 1/8-inch hex drive for use with standard hex keys or Allen wrenches
• 5/8-inch overall length suits medium-depth engagement applications
• Headless design seats flush or below the workpiece surface

Compatibility

Designed as a standard 1/4-20 UNC headless cup point set screw, compatible with any tapped hole conforming to 1/4-20 UNC thread standards in shaft collars, pulleys, couplings, and similar mechanical components.

Installation Notes

Install and remove using a 1/8-inch hex key. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound if vibration resistance is required. Follow applicable mechanical assembly standards and torque guidelines for 1/4-20 stainless fasteners as specified in your project documentation.
