Value Collection R63263443 Set Screw 5/16-24 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION R63263443 is a cup point set screw used to lock shafts, collars, pulleys, and similar components in position without protruding above the mating surface. Manufactured from 18-8 stainless steel, it resists corrosion in wet or chemical-exposed environments. The thread specification is 5/16-24 UNF with an overall length of 1/4 inch. Drive is a 5/32-inch hex socket, which accepts a standard Allen-style key. Machinists, millwrights, and maintenance technicians install this type of fastener in light to medium mechanical assemblies where surface-flush retention is required.

Cup point set screws are widely used in industrial and commercial mechanical assemblies including motor shafts, conveyor components, gearboxes, and rotating equipment. The 5/16-24 UNF thread pitch is common in precision mechanical and instrumentation applications. The 18-8 stainless steel construction makes this screw suitable for environments with moisture exposure, mild chemical contact, or where corrosion resistance is a priority over high tensile strength.

Key Features

• Cup point geometry bites into the shaft for positive holding without full penetration
• 18-8 stainless steel construction provides corrosion resistance in wet or chemical environments
• 5/16-24 UNF thread for precision mechanical applications
• 5/32-inch hex drive accepts a standard Allen key
• Overall length of 1/4 inch keeps fastener flush or recessed in the threaded bore

Compatibility

Designed as a standard 5/16-24 UNF cup point set screw suitable for threaded bores in shafts, hubs, collars, and similar mechanical components requiring flush-mount fastening.

Installation Notes

Machinists or maintenance technicians typically install set screws using a properly sized hex key — in this case 5/32 inch — to avoid rounding the drive socket. Ensure the mating bore is clean and threads are undamaged before installation. De-energize and lock out any rotating equipment before servicing shaft-mounted components. Refer to equipment manufacturer torque guidelines for this fastener size and material grade.
