Value Collection R63642447 Set Screw 5/16-18 X 1/2 in Brass

Product Description

The VALUE COLLECTION R63642447 is a cup point set screw used to secure components such as collars, hubs, gears, and pulleys to shafts without a protruding head. Machined from brass, this fastener measures 5/16-18 thread size with an overall length of 0.5 inches. Drive is a 5/32-inch hex (Allen key) socket. The cup point bites into the shaft surface to resist rotation and axial movement. Brass construction makes it well suited for applications requiring corrosion resistance, electrical conductivity, or non-sparking properties. This screw is installed by maintenance technicians, machinists, and trade professionals across HVAC, plumbing, and light industrial equipment.

This set screw is a fit for shaft-to-hub clamping applications in residential and light commercial mechanical assemblies. Common uses include motor shafts, valve stems, pump impellers, and equipment frames where a flush or recessed fastener is required. The UNC thread standard ensures broad compatibility with standard inch-series tapped holes. Sold individually; minimum order quantity is 10 units.

Key Features

• Cup point geometry bites into shaft surface for firm, reliable grip
• Brass material provides corrosion resistance and non-sparking characteristics
• 5/16-18 UNC thread for compatibility with standard inch-series tapped holes
• 5/32-inch hex drive works with standard Allen keys and hex-key drivers
• Headless design sits flush or below the surface for clearance-critical assemblies

Compatibility

Designed as a standard inch-series set screw for use in any 5/16-18 UNC tapped hole requiring a cup point, headless fastener in brass.

Installation Notes

Install with a 5/32-inch hex key or Allen driver. De-energize and lock out any rotating machinery before servicing shaft-mounted components. Do not overtighten brass fasteners against hardened steel shafts, as the cup point may deform under excessive torque. Follow applicable equipment manufacturer torque guidelines and relevant mechanical codes for the installation context.
