Value Collection R63004922 Set Screw 8-32 Grade 316

Product Description

The VALUE COLLECTION R63004922 is a cup point set screw designed for mechanical fastening applications where a secure, non-protruding hold is required. Manufactured from Grade 316 stainless steel, this fastener offers excellent corrosion resistance, making it suitable for harsh or wet environments. The screw features an 8-32 UNC thread with an overall length of 3/8 inches and is driven by a 5/64-inch hex key. It is commonly installed by machinists, pipefitters, millwrights, and maintenance technicians working on shafts, collars, pulleys, and mechanical assemblies across industrial and trade applications.

This set screw is well suited for use in HVAC equipment assemblies, pump and motor shaft collars, plumbing fixture components, and general mechanical assemblies where stainless steel corrosion resistance is a priority. The cup point bites into the shaft surface to resist rotational and axial movement without requiring a through-hole. Applications range from light industrial machinery to trade equipment maintenance in environments exposed to moisture, chemicals, or salt air.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• Cup point geometry provides positive bite on shaft surfaces to resist rotation and axial shift
• 8-32 UNC thread for broad compatibility with standard inch-series tapped holes
• 5/64-inch hex drive allows installation with standard Allen or hex key sets
• Overall length of 3/8 inches suits shallow collar and hub applications
• Headless design sits flush with or below the mating surface to eliminate protrusion hazards

Compatibility

Designed as a standard 8-32 UNC cup point set screw for use in any tapped hole or collar that accepts an 8-32 thread pitch and requires a cup point fastener.

Installation Notes

Installation requires a 5/64-inch hex key or Allen wrench; ensure the mating tapped hole is clean and free of debris before threading. Depower or de-energize any equipment before adjusting or replacing set screws in rotating assemblies. Apply thread-locking compound if vibration is a concern, following the compound manufacturer's cure time before returning the assembly to service. Follow applicable mechanical codes and torque guidelines for the specific assembly being serviced.
