Value Collection 93920 Set Screw 8-32 5/16 in Cup Point 50-pack

Product Description

The VALUE COLLECTION 93920 is a cup point set screw designed for secure, flush fastening applications across industrial, mechanical, and HVAC equipment assemblies. Sized at 8-32 UNC thread with a 5/16-inch overall length, this headless screw seats completely below the workpiece surface, locking shafts, collars, and pulleys in place without protruding hardware. The cup point geometry bites into the mating shaft to resist rotation and axial movement. Manufactured from Grade 18-8 stainless steel, it offers solid corrosion resistance for both indoor and moderate outdoor environments. A 5/64-inch hex drive is required for installation. This pack contains 50 pieces.

This set screw is suited for use in HVAC blower wheel hubs, motor shaft collars, fan blade assemblies, pulley mounts, and general mechanical equipment where a low-profile, vibration-resistant fastener is needed. The 8-32 UNC thread size is common in light-duty mechanical assemblies found in residential and light commercial equipment. Grade 18-8 stainless construction makes these appropriate for environments where mild moisture exposure or chemical contact is a concern.

Key Features

• Cup point geometry grips mating shaft surfaces to resist rotation and axial displacement
• 8-32 UNC thread, 5/16-inch overall length for precise, compact fitment
• Grade 18-8 stainless steel construction for corrosion resistance
• Headless design allows fully flush or recessed installation
• 5/64-inch hex (Allen) drive for standard L-key or hex bit installation
• Sold in a 50-piece pack to support service stock and repeat applications

Compatibility

Designed as a general-purpose replacement or service fastener for any assembly using 8-32 UNC threaded set screw seats requiring a 5/16-inch length cup point style screw.

Installation Notes

Installation requires a 5/64-inch hex key or matching hex bit driver. Verify that the mating threaded hole is clean and free of debris before threading. De-energize all equipment and relieve any stored mechanical energy before servicing shaft collars or drive components. Do not overtighten, as cup point set screws in stainless steel can gall if excessive torque is applied without lubrication.
