Value Collection R63260160 Set Screw 2-56 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION R63260160 is a 2-56 UNC cup point set screw manufactured from 18-8 stainless steel. Set screws are headless fasteners that thread fully into a tapped hole and bear down on a mating surface to lock shafts, collars, pulleys, and similar components in position. This screw measures 3/8 inches in overall length and accepts a 0.035-inch hex key for installation and removal. The 18-8 stainless steel construction provides corrosion resistance suitable for general industrial, HVAC, plumbing, and light marine applications. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This set screw is suited for small-bore assemblies requiring a secure, flush-mount locking fastener. The cup point geometry bites into the mating shaft to resist rotation and axial movement without requiring a separate locking mechanism. Typical applications include motor shaft collars, set collar assemblies, valve actuator linkages, and precision instrument hardware where a 2-56 thread pitch is specified. This item is sold individually but carries a minimum order quantity of 100 pieces per order.

Key Features

• Cup point geometry bites into mating shaft surface to resist axial and rotational movement
• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Headless hex drive design sits flush or below the surface of the tapped component
• 0.035-inch hex key drive accommodates standard miniature allen wrenches
• UNC thread standard ensures broad compatibility with inch-standard tapped holes
• 3/8-inch overall length provides adequate thread engagement for small-bore collars and hubs

Compatibility

Designed for use in any application with a 2-56 UNC tapped hole requiring a cup point set screw. Consult your assembly drawings to confirm thread size, length, and point type before installation.

Installation Notes

Installation requires a 0.035-inch hex key. Ensure the tapped hole is clean and free of debris before threading the screw. Do not exceed the torque rating specified by the equipment manufacturer for 2-56 fasteners, as over-torquing small-diameter screws can cause thread stripping or screw shear. De-energize and lock out any rotating equipment before servicing shaft collar assemblies.
