Value Collection R63006241 Set Screw 5/16-18 Cup Point 18-8

Product Description

The VALUE COLLECTION R63006241 is a cup point set screw used to secure components such as collars, hubs, pulleys, and gears onto shafts without protruding hardware. It features a 5/16-18 UNC thread and measures 1-1/4 inches in length under head. Manufactured from Grade 18-8 stainless steel, it offers good corrosion resistance in light industrial and mechanical service environments. The square drive style requires a square-bit driver for installation and provides reliable torque transfer. This fastener is sold in a minimum quantity of 5 pieces per order.

Cup point set screws like this one are commonly used in mechanical assemblies across HVAC, electrical, plumbing, and general industrial applications. The cup point bites into the shaft surface to resist rotational and axial movement, making it well suited for positioning and locking tasks on rotating equipment and structural components. This screw is typically installed by maintenance technicians and mechanical tradespeople working on equipment assemblies, pump drives, fan hubs, and similar systems.

Key Features

• Cup point geometry bites into shaft material to resist movement under load
• Grade 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• 5/16-18 UNC thread size for broad compatibility with standard tapped holes
• Square drive reduces cam-out risk during installation
• 1-1/4 inch length under head suits moderate shaft engagement depths
• Headless design sits flush, eliminating snagging hazards on rotating assemblies

Compatibility

Designed as a standard UNC thread set screw for use in any tapped 5/16-18 threaded hole requiring a cup point headless fastener in stainless steel.

Installation Notes

Installation requires a square-bit driver sized to the screw socket. Always de-energize and lock out rotating equipment before installing or adjusting set screws on shaft-mounted components. Verify the tapped hole is clean and free of debris before threading the screw in. Follow applicable equipment manufacturer torque guidelines and any relevant ANSI or industry fastener standards for the application.
