Value Collection 2-SC-50C-150 Set Screw 1/2-13 Grade 316

Product Description

The VALUE COLLECTION 2-SC-50C-150 is a 1/2-13 x 1-1/2 inch cup point set screw manufactured from Grade 316 stainless steel. The cup point tip bites into the mating surface to resist rotational and axial movement without requiring an exposed fastener head. The hex drive socket accepts a standard hex key for installation in tight or recessed applications. This fastener is supplied uncoated, relying on the inherent corrosion resistance of 316 stainless to perform in wet, chemical, or marine-adjacent environments. It is suited for use by millwrights, pipefitters, maintenance technicians, and mechanical contractors working on equipment assemblies where fastener exposure to moisture or corrosive agents is a concern.

This set screw is used in shaft-to-hub connections, collars, couplings, pulleys, and similar mechanical assemblies found in industrial, commercial, and trade service environments. The 1/2-13 thread designation indicates a 1/2 inch nominal diameter with 13 threads per inch in the Unified National Coarse thread series. Grade 316 stainless steel offers improved chloride and pitting resistance compared to Grade 304, making this fastener appropriate for plumbing, HVAC, pool equipment, and light marine mechanical applications.

Key Features

• Cup point tip locks onto shaft surfaces to prevent slipping under load
• Grade 316 stainless steel provides superior corrosion resistance in wet and chemical environments
• Hex socket drive for use with standard hex keys in confined spaces
• Uncoated finish retains full dimensional tolerance on threads
• 1/2-13 UNC thread with 1-1/2 inch engagement length for secure clamping force

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 1/2-13 UNC cup point set screw in Grade 316 stainless steel.

Installation Notes

Installation is performed by threading the set screw into a pre-tapped hole using a calibrated hex key of the correct size. Ensure the mating shaft or component is clean and free of debris before seating the cup point. De-energize or lock out any equipment before servicing shaft assemblies. Do not substitute a lower stainless grade where Grade 316 is specified, as corrosion resistance properties will differ.
