Value Collection R63000024 Set Screw 5/16-18 X 3/8 in

Product Description

The VALUE COLLECTION R63000024 is a 5/16-18 UNC cup point set screw manufactured from Grade 316 stainless steel. Set screws are headless fasteners threaded along their full length and driven with an allen key — in this case a 3/32-inch hex key. The cup point style bites into the mating shaft surface to resist rotation and axial movement without requiring a nut or clearance for a bolt head. Grade 316 stainless provides strong corrosion resistance, making this fastener well suited for wet, marine, or chemically aggressive environments. Overall length is 3/8 inches. Trade professionals in HVAC, plumbing, and mechanical service will encounter this fastener in collar, coupling, and set collar applications.

This set screw is used in applications where a shaft, rod, or cylindrical component must be secured inside a collar, hub, pulley, or coupling. The cup point concentrates clamping force on a small area of the shaft, which is appropriate for permanent or semi-permanent installations. Grade 316 stainless makes it a practical choice for outdoor mechanical assemblies, pump components, pool equipment, and any installation where moisture or salt exposure is a concern. Minimum order quantity is 100 pieces per order; package quantity is 1 unit.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and marine environments
• Cup point geometry concentrates clamping load to grip shaft surfaces effectively
• 5/16-18 UNC thread standard ensures broad dimensional compatibility with standard tapped holes
• 3/32-inch hex drive accepts standard allen keys and hex-key drivers
• Headless design allows flush or recessed installation with no protrusion above the collar face
• 3/8-inch overall length suits shallow collar and hub applications

Compatibility

Designed for use in any standard 5/16-18 UNC tapped set screw hole requiring a cup point fastener in Grade 316 stainless steel.

Installation Notes

Installation requires a 3/32-inch hex key or allen driver. Verify the mating collar or hub is tapped to 5/16-18 UNC before installation. De-energize or shut down any rotating equipment fully before servicing set screw connections. Do not overtighten — cup point set screws can deform soft shaft materials if excessive torque is applied.
