Value Collection R63006249 Set Screw 5/16-18 X 1 in

Product Description

The VALUE COLLECTION R63006249 is a 5/16-18 UNC cup point set screw measuring 1 inch in length, manufactured from grade 18-8 stainless steel. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a collar, pulley, gear, or knob — against a shaft or mating surface. The cup point configuration bites into the mating surface under torque, providing reliable resistance to rotational and axial movement. The 18-8 stainless steel construction offers good corrosion resistance in moderately harsh environments. Installation requires a square drive tool matched to the socket size. This fastener is installed by maintenance technicians, millwrights, and mechanical contractors across a wide range of industrial and mechanical service applications.

This set screw is suited for general mechanical assembly and repair work in residential and commercial settings. Common applications include securing shaft collars, adjusting hand wheel positions, locking set positions on HVAC components, and general mechanical assembly where a flush or recessed fastener is required. The cup point is particularly effective in applications where the fastener seats into a drilled or dimpled shaft for added retention. Minimum order quantity is 5 pieces.

Key Features

• Cup point tip bites into mating surface for strong rotational and axial hold
• Grade 18-8 stainless steel construction resists corrosion in wet or mildly corrosive environments
• 5/16-18 UNC thread for broad compatibility with standard inch-series tapped holes
• Fully threaded, headless design allows flush or below-surface installation
• Square drive socket for positive driver engagement and high torque transfer
• 1 inch length under head provides substantial thread engagement depth

Compatibility

Designed as an OEM-style and aftermarket replacement set screw for standard 5/16-18 UNC tapped holes in shaft collars, pulleys, gears, and mechanical assemblies requiring a cup point headless fastener.

Installation Notes

Installation requires a square drive key or bit sized to match the socket. De-energize or lock out any rotating equipment before installing or removing set screws per applicable OSHA and facility lockout/tagout procedures. Do not over-torque; apply firm, even torque until the cup point seats securely against the shaft surface. A thread-locking compound may be used where vibration is a concern.
