Value Collection R63263161 Set Screw 5/16-24 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION R63263161 is a 5/16-24 x 1/2-inch cup point set screw manufactured from Grade 18-8 stainless steel. Set screws are fully threaded, headless fasteners used to secure a component — such as a collar, gear, or pulley — against a shaft by bearing force directly through the point. This cup point configuration concentrates clamping force at a circular rim, providing strong resistance to rotational movement. The 5/32-inch hex drive accepts a standard Allen wrench. This screw is installed by machinists, millwrights, pipefitters, and maintenance technicians in a wide range of mechanical assembly and repair applications.

This set screw is suited for light to medium-duty mechanical assemblies where corrosion resistance is a priority. The 5/16-24 UNF (Unified National Fine) thread pitch provides good vibration resistance and precise axial adjustment. Grade 18-8 stainless steel construction makes it appropriate for use in humid, wet, or mildly corrosive environments, including HVAC equipment, pump assemblies, and general industrial machinery. The 1/2-inch overall length fits standard shaft collar and hub applications in that thread class.

Key Features

• Cup point design concentrates clamping force for strong rotational hold on shaft assemblies
• 5/16-24 UNF thread standard for fine-pitch precision and improved vibration resistance
• Grade 18-8 stainless steel construction resists corrosion in wet and humid environments
• 5/32-inch hex drive compatible with standard Allen or hex key wrenches
• 1/2-inch overall length suits common shaft collar and hub mounting configurations

Compatibility

Designed as a standard 5/16-24 UNF cup point set screw for use in any threaded bore requiring that thread size and a 1/2-inch overall length with a hex drive.

Installation Notes

Installation is performed by inserting the screw into a pre-tapped or existing 5/16-24 UNF threaded hole and tightening with a 5/32-inch hex key. Ensure the mating shaft or component surface is clean and properly positioned before applying torque. Do not over-drive — cup point set screws can deform the shaft surface if over-tightened, which complicates future removal. Follow applicable machine safety lockout and tagout (LOTO) procedures before servicing any assembly containing rotating components.
