Value Collection R63006022 Set Screw 1/2-13x3/4 Cup Point 18-8

Product Description

The VALUE COLLECTION R63006022 is a 1/2-13 x 3/4 inch cup point set screw manufactured from Grade 18-8 stainless steel. Set screws are fully threaded fasteners with no head, designed to secure a component — such as a collar, pulley, gear, or hub — against or onto a shaft. The cup point geometry bites into the mating surface for a strong, reliable hold under vibration and load. The square drive requires a square-key wrench for installation and removal. Grade 18-8 stainless steel provides corrosion resistance suitable for indoor and outdoor applications where moisture or mild chemical exposure is a concern.

This set screw is suited for general industrial, mechanical, and maintenance applications across HVAC equipment, plumbing assemblies, electrical enclosures, and pool equipment where a headless fastener is required to fix rotating or sliding components. The 1/2-13 UNC thread is a coarse-thread standard, making it compatible with the widest range of threaded inserts, hubs, and collars machined to that specification. It is commonly installed by maintenance technicians, millwrights, and mechanical contractors working on equipment shaft assemblies.

Key Features

• Cup point tip bites into shaft surface for secure, vibration-resistant hold
• Square drive for positive torque transfer with a square-key wrench
• Grade 18-8 stainless steel construction for corrosion resistance
• Coarse UNC thread form for broad compatibility with standard tapped holes
• Fully threaded, headless design sits flush or below the surface of the mating part

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw suitable for use in any application requiring a headless fastener with that thread size and a square drive recess.

Installation Notes

Installation requires a square-key (square socket) wrench sized to the drive recess. De-energize and lock out any equipment before accessing shaft assemblies or rotating components. Do not over-tighten, as excessive force can damage the cup point or the mating shaft. Verify thread engagement depth meets the requirements of the application before returning equipment to service.
