Value Collection R63263488 Set Screw 5/16-24 X 5/16 in Cup Point

Product Description

The VALUE COLLECTION R63263488 is a 5/16-24 UNF cup point set screw designed for mechanical assemblies requiring a secure, flush-mount fastener. Manufactured from grade 18-8 stainless steel, this fastener offers corrosion resistance suitable for general industrial and trade applications. The cup point geometry bites into the mating surface to resist rotational and axial movement without a protruding head. Driven with a 5/32-inch hex key, it is commonly installed by millwrights, machinists, pipefitters, and maintenance technicians working on shafts, collars, and mechanical couplings.

This set screw is appropriate for use in light to medium-duty clamping applications across residential and commercial mechanical systems. Typical installations include shaft-to-hub connections, set-collar retention, and pulley or gear locking on rotating assemblies. The 5/16-24 UNF thread provides finer thread engagement than UNC equivalents, making it a preferred choice where vibration resistance or precise axial adjustment is needed.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• Cup point geometry grips mating shaft surfaces to resist slippage under load
• 5/16-24 UNF thread standard provides fine-pitch engagement and vibration resistance
• 5/32-inch hex drive for standard Allen key or hex bit installation
• Headless design sits flush or below surface, eliminating snagging hazards on rotating parts

Compatibility

Designed as an OEM-style replacement or maintenance stock fastener for mechanical assemblies using 5/16-24 UNF threaded set screw seats with cup point geometry.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a calibrated 5/32-inch hex key or Allen driver. Always de-energize and lock out rotating equipment before accessing shaft collars or couplings. Do not overtighten — excessive torque can shear stainless fasteners or damage soft shaft surfaces. Verify thread engagement depth meets the requirements of the assembly design before returning equipment to service.
