Value Collection R63263922 Set Screw 5/8-11 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION R63263922 is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping force without a protruding head. Manufactured from Grade 18-8 stainless steel, this screw offers solid corrosion resistance in wet, outdoor, and mildly chemical environments. The cup point geometry bites into the mating surface to resist rotation and axial movement under load. Thread size is 5/8-11 UNC, with an overall length of 5/8 inches and a 5/16-inch hex drive, making it compatible with standard hex keys and Allen wrenches found in any trade toolbox.

This set screw is used in shaft-collar, pulley, gear, and hub assemblies across HVAC equipment, pumping systems, fan drives, and general mechanical installations. It is suited for both residential and light commercial equipment where stainless fasteners are specified to prevent rust-related seizure. Installers working on motor mounts, bearing housings, and drive components will find this size commonly required when servicing or assembling rotating equipment.

Key Features

• Cup point tip bites into shaft surface to resist slippage under torque and axial load
• Grade 18-8 stainless steel provides corrosion resistance in wet and outdoor service environments
• 5/8-11 UNC thread standard ensures broad compatibility with standard tapped holes
• 5/16-inch hex drive accepts standard Allen keys and hex bit drivers
• Headless design sits flush or below the surface to eliminate snag points in rotating assemblies

Compatibility

Designed as a standard UNC set screw for use in any 5/8-11 tapped hole requiring a cup point, headless fastener in stainless steel.

Installation Notes

Set screws of this type are installed by licensed mechanics and trained technicians using a 5/16-inch hex key or Allen driver. Always de-energize and lock out rotating equipment before accessing shaft assemblies. Tighten to the torque specification provided by the equipment manufacturer for the shaft diameter and material in use. Avoid cross-threading by hand-starting the screw before applying drive torque.
