Value Collection R63260926 Set Screw 8-32 X 1 in Cup Point

Product Description

The VALUE COLLECTION R63260926 is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies. This screw features an 8-32 UNC thread with a 1-inch overall length and is driven by a 5/64-inch hex key. Manufactured from Grade 18-8 stainless steel, it provides reliable corrosion resistance in environments exposed to moisture or mild chemicals. The cup point digs into the mating surface to resist rotation and axial movement, making it well suited for shaft-to-hub connections, collars, and similar clamping applications. Installation is performed by machinists, maintenance technicians, and industrial trades working with precision mechanical components.

This set screw is used in residential, commercial, and light industrial mechanical assemblies where a headless fastener is required to lock a component onto a shaft or within a bore. Typical applications include motor shafts, shaft collars, pulleys, and gears where a flush or recessed fastener profile is necessary. The cup point style provides a positive bite into softer shaft materials, distributing holding force without requiring a keyway. Minimum order quantity is 100 pieces, making this screw appropriate for shop stock or maintenance inventory replenishment.

Key Features

• 8-32 UNC thread for compatibility with standard inch-series tapped holes
• Cup point geometry bites into mating surfaces to resist rotation and axial movement
• Grade 18-8 stainless steel construction provides corrosion resistance in damp or mildly corrosive environments
• 5/64-inch hex drive allows installation with a standard Allen key or hex bit
• Headless design sits flush or below the surface for clearance-sensitive assemblies
• 1-inch overall length provides extended thread engagement for demanding clamping loads

Compatibility

Designed as a standard 8-32 UNC cup point set screw suitable for any tapped hole or threaded insert meeting that thread specification in mechanical, HVAC, or industrial applications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/64-inch hex key or Allen driver. Always ensure the tapped hole is clean and threads are undamaged before installation. Torque to the fastener manufacturer's published specification for the material and application. Do not over-drive the set screw, as excessive force can strip the hex socket or damage the mating shaft surface.
