Value Collection R63263269 Set Screw 3/8-16 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION R63263269 is a 3/8-16 x 5/8 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 collar, gear, pulley, or sprocket — against a shaft, preventing rotational or axial movement. This screw is driven with a 3/16 inch hex key and follows the UNC thread standard. The cup point style bites into the mating surface to provide firm, reliable holding power. Grade 18-8 stainless steel offers good corrosion resistance, making this fastener suitable for environments where moisture or mild chemical exposure is a concern.

This set screw is used across a wide range of mechanical and industrial applications, including HVAC equipment assemblies, pump and motor shaft retention, plumbing fixture hardware, and general mechanical maintenance. It is appropriate for both residential and light commercial service work wherever a UNC 3/8-16 thread pattern is required. Technicians and tradespeople routinely stock this size for field repairs and preventive maintenance tasks.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard inch-series tapped holes
• 5/8 inch overall length suits medium-depth shaft engagement applications
• Cup point geometry provides positive bite and resistance to loosening under vibration
• Grade 18-8 stainless steel construction resists corrosion and oxidation
• 3/16 inch hex drive compatible with standard hex keys and allen drivers
• Headless design allows flush or below-surface installation

Compatibility

Designed as a standard UNC 3/8-16 set screw for use in any application requiring a 3/8-16 tapped hole with a cup point headless fastener.

Installation Notes

Installation is performed with a 3/16 inch hex key or hex driver. Ensure the tapped hole is clean and free of debris before threading the screw. Disengage power and lock out any rotating equipment before servicing shaft-mounted components secured by set screws. Do not overtighten, as excessive torque can deform the cup point or strip the thread on softer shaft materials.
