Value Collection 93972 Set Screw 1/4-28x1/2 Cup Point Ss 18-8 50pk

Product Description

The VALUE COLLECTION 93972 is a 1/4-28 cup point set screw manufactured from grade 18-8 stainless steel. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a collar, pulley, or gear — against a shaft or within a housing. The 1/4-28 UNF thread pitch provides fine thread engagement for secure holding in metal assemblies. Drive is via a 1/8-inch hex key. The cup point geometry bites into the mating surface to resist rotation and axial movement. Sold in a package of 50 units, this SKU suits maintenance shops, production lines, and field service kits that require a reliable stainless steel fastener.

These set screws are suited for mechanical assemblies where corrosion resistance is required, such as food processing equipment, marine hardware, HVAC shaft collars, pump components, and general industrial machinery. The 18-8 stainless steel grade provides good resistance to oxidation and mild chemicals. The 1/2-inch overall length and fine 1/4-28 UNF thread make this screw appropriate for light- to medium-duty clamping applications. Installers working in corrosive or washdown environments commonly specify 18-8 stainless over carbon steel fasteners for longevity.

Key Features

• 1/4-28 UNF fine thread for precise engagement and secure clamping force
• Cup point geometry bites into mating shaft surface to resist slippage
• Grade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• 1/8-inch hex drive — standard hex key or T-handle required for installation
• 1/2-inch overall length suits shallow-bore and thin-wall applications
• Packaged in quantities of 50 for shop stock and service kit replenishment

Compatibility

Designed as a standard 1/4-28 UNF cup point set screw compatible with any threaded bore or set screw hole requiring a 1/4-28 fine thread fastener and a 1/8-inch hex drive.

Installation Notes

Set screws are typically installed by machinists, millwrights, or maintenance technicians using a 1/8-inch hex key or L-wrench. Ensure the mating threaded bore is clean and free of debris before threading. Do not exceed the torque rating of the thread size for the material being fastened — consult published fastener torque tables for 1/4-28 stainless steel. Apply a thread-locking compound if vibration loosening is a concern in the application.
