Value Collection R63000060 Set Screw 5/16-18 X 1/2 in

Product Description

The VALUE COLLECTION R63000060 is a 5/16-18 x 1/2 inch cup point set screw manufactured from Grade 316 stainless steel. It features a 3/32 inch hex drive and a unified national coarse (UNC) thread standard. The cup point tip bites into the mating surface to resist rotation and axial movement, making it well suited for securing shafts, collars, and hubs in mechanical assemblies. This fastener is installed by licensed trades and maintenance technicians working in industrial, HVAC, and mechanical system environments where corrosion resistance is a priority.

This set screw is used in applications where a flush or below-surface fastening profile is required. Grade 316 stainless steel provides elevated resistance to chlorides and harsh chemicals compared to Grade 304, making it appropriate for marine, food-service, chemical, and outdoor mechanical assemblies. It is commonly used to lock pulleys, gears, and couplings onto shafts in both residential and light commercial mechanical systems.

Key Features

• Cup point tip grips mating shaft surface to prevent rotation and axial slippage
• Grade 316 stainless steel construction offers superior corrosion resistance in harsh or wet environments
• 5/16-18 UNC thread for broad compatibility with standard tapped holes
• 3/32 inch hex drive accommodates standard hex keys and T-handle drivers
• Overall length of 1/2 inch provides a compact, low-profile fastening solution

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 5/16-18 UNC threaded cup point set screw with a 3/32 inch hex drive.

Installation Notes

Installation requires a 3/32 inch hex key or Allen driver. Always de-energize or lock out the equipment before accessing rotating components such as shafts or collars. Ensure the tapped hole is clean and free of debris before threading in the screw. Do not exceed the torque capacity of the stainless steel alloy, as over-torquing can cause galling or thread damage in stainless fasteners.
