Value Collection R40322142 Set Screw 3/8-16 X 1 in Cup Point

Product Description

The VALUE COLLECTION R40322142 is a 3/8-16 x 1 inch cup point set screw manufactured from Grade 18-8 stainless steel. Set screws are fully threaded fasteners with no head — they seat flush or below the surface of a workpiece to lock a component, such as a collar, pulley, or gear, onto a shaft. This screw uses a 3/16 inch hex key drive and a cup point tip, which bites into the mating surface to resist rotation and axial movement. The 18-8 stainless steel construction provides good corrosion resistance for general industrial, HVAC, plumbing, and mechanical assembly applications. Installation requires a standard 3/16 inch hex key or Allen wrench.

This set screw is suited for use in residential and commercial mechanical assemblies where a headless, flush-mount locking fastener is required. Cup point set screws are commonly used in shaft collars, shaft couplings, sheaves, pulleys, and similar rotary components. The 3/8-16 UNC thread size is a common coarse-thread standard found across a wide range of industrial and trade equipment. The 1 inch overall length provides sufficient thread engagement for medium-duty locking applications. Sold individually with a minimum order quantity of 10 pieces.

Key Features

• Cup point tip bites into mating shaft surface for positive locking grip
• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 1 inch overall length for adequate thread engagement in medium-duty assemblies
• 3/16 inch hex key drive — compatible with standard Allen wrenches
• Grade 18-8 stainless steel construction for corrosion resistance in wet or humid environments
• Fully threaded, headless design seats flush or below surface

Compatibility

Designed as a standard 3/8-16 UNC cup point set screw suitable for use in any application requiring that thread size and overall length in a headless fastener configuration.

Installation Notes

Installation requires a 3/16 inch hex key or Allen wrench. Ensure the tapped hole is clean and free of debris before threading. Do not overtighten — cup point set screws can be damaged or can mar the mating shaft excessively if torqued beyond the material rating. Consult applicable mechanical assembly standards for torque guidance on stainless steel fasteners of this thread size.
