Value Collection R63006484 Set Screw 5/16-18 X 1/2 in

Product Description

The VALUE COLLECTION R63006484 is a 5/16-18 x 1/2-inch cup point set screw manufactured from 18-8 stainless steel. Set screws are fully threaded fasteners with no head, used to secure a component — such as a shaft collar, pulley, or gear — against a mating surface by direct contact pressure. The cup point tip bites into the mating surface to resist rotation and axial movement. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, chemical-exposure, or outdoor environments where carbon steel fasteners would be unsuitable. This screw uses a square drive, which requires a square-drive bit or key for installation and offers good torque transfer without cam-out.

This set screw is a standard UNC-threaded fastener suited for light mechanical assemblies, HVAC shaft collar applications, plumbing fixture hardware, electrical enclosure components, and general trade maintenance tasks. The 5/16-18 thread size and 1/2-inch length under head make it a common size across a wide range of industrial and trade applications where a compact, headless locking fastener is required. It is sold in a minimum quantity of 5 units per order.

Key Features

• Cup point tip bites into mating surface for reliable hold against axial and rotational movement
• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Square drive provides positive torque engagement and reduces risk of cam-out
• Standard UNC 5/16-18 thread for broad compatibility with threaded holes and collars
• Fully threaded, headless design sits flush or below surface for clearance-critical assemblies

Compatibility

Designed as a standard UNC 5/16-18 replacement or maintenance set screw for shaft collars, pulleys, couplings, and similar mechanical components that require a headless cup point fastener in this thread size.

Installation Notes

Installation requires a square-drive bit or key sized to this screw. Power down any rotating equipment and lock out or tag out the system before installing or adjusting set screws on shaft-mounted components. Ensure the threaded receiver is clean and free of debris before threading in. Do not exceed the torque capacity of the drive recess, and verify the cup point seats fully against the shaft surface before returning equipment to service.
