Value Collection R63260222 Set Screw 4-40 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION R63260222 is a 4-40 x 1/2 inch cup point set screw manufactured from Grade 18-8 stainless steel. Set screws are fully threaded fasteners with no head that seat flush with or below the surface of a workpiece, using internal drive engagement to apply clamping force. This screw uses a hex drive and a cup point tip, which bites into the mating surface to resist rotation and axial movement. Licensed tradespeople and mechanical assemblers install these fasteners in applications requiring corrosion resistance and secure locking without a protruding head profile.

This set screw is suited for light-duty mechanical assemblies where a compact, headless fastener is required. Common applications include securing collars, hubs, pulleys, and gears onto shafts in HVAC equipment, plumbing fixtures, and general industrial assemblies. The 4-40 thread size is a fine-pitch UNC designation appropriate for small components. The 1/2 inch overall length provides adequate thread engagement for thin to medium-wall workpieces. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• Cup point tip bites into shaft or mating surface for strong resistance to rotation and axial shift
• Hex drive socket accepts a 0.050 inch hex key for precise torque application in tight spaces
• Grade 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• Fully threaded, headless design seats flush or below surface for clean, low-profile installations
• UNC 4-40 thread standard ensures broad tooling and hardware compatibility
• 1/2 inch overall length suits thin to medium-wall collars, hubs, and similar components

Compatibility

Designed as a standard UNC 4-40 x 1/2 inch cup point set screw suitable for general mechanical assemblies requiring a headless stainless steel fastener with hex drive.

Installation Notes

Installation is performed using a 0.050 inch hex key or Allen wrench. Ensure the mating hole is clean and free of debris before threading the screw. Disengage power or isolate the assembly from any moving components before installation or removal. Do not exceed the rated engagement depth of the workpiece material to avoid thread stripping.
