Value Collection R63263440 Set Screw 5/16-18 X 2 in

Product Description

The VALUE COLLECTION R63263440 is a stainless steel set screw designed for secure, tool-accessible fastening in mechanical assemblies. This cup point set screw features a 5/16-18 UNC thread and an overall length of 2 inches, driven by a 3/32-inch hex key. The 18-8 stainless steel construction provides corrosion resistance suitable for general industrial, HVAC, and plumbing applications. Cup point geometry bites into the mating surface to resist rotation and axial movement without a protruding head. Installed by machinists, maintenance technicians, pipefitters, and HVAC mechanics where a flush or recessed fastener is required.

This set screw is suited for use in shaft collars, pulleys, couplings, and other mechanical components where a headless fastener is needed to lock a part onto a shaft or within a bore. The cup point style is one of the most common configurations for general-purpose set screw applications across residential and commercial mechanical systems. It is well-suited for both new installations and replacement fastening in existing assemblies.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard tapped holes
• 2-inch overall length accommodates deeper engagement in thick hubs or collars
• Cup point geometry creates a positive bite into the mating shaft surface
• 18-8 stainless steel construction resists corrosion in wet or humid environments
• 3/32-inch hex drive fits standard hex keys and L-wrenches
• Headless design sits flush or below the surface for clearance-sensitive assemblies

Compatibility

Designed as an OEM-style replacement or standard replacement set screw for mechanical assemblies requiring a 5/16-18 UNC cup point headless fastener.

Installation Notes

Installation requires a 3/32-inch hex key or Allen wrench. De-energize and lock out all rotating equipment before servicing any shaft or coupling fastener. Threads should be clean and free of debris before installation. Follow applicable mechanical and safety codes for the equipment being serviced.
