Value Collection R63260642 Set Screw 6-32 Cup Point Ss 18-8

Product Description

The VALUE COLLECTION R63260642 is a cup point set screw designed for mechanical assemblies where a fastener must secure a shaft, collar, or component without a protruding head. This screw features a 6-32 UNC thread and an overall length of 5/16 inches, making it suitable for tight-clearance applications. The cup point geometry bites into mating surfaces to resist rotation and axial movement under load. Constructed from Grade 18-8 stainless steel, it offers corrosion resistance suitable for indoor and moderately wet environments. Drive engagement is through a 1/16 inch hex key socket. Installed by machinists, maintenance technicians, and assembly professionals across a range of industrial and light mechanical applications.

This set screw is used in applications such as securing pulleys, gears, knobs, and collars to shafts in mechanical assemblies. The fine 6-32 UNC thread provides consistent engagement in tapped holes found in small machine components. The compact 5/16 inch length suits thin-wall hubs and close-tolerance assemblies where a longer fastener would interfere with adjacent components. Grade 18-8 stainless steel construction makes it appropriate for food-processing, HVAC panel hardware, and other environments where mild corrosion resistance is required alongside moderate mechanical strength.

Key Features

• Cup point geometry locks shaft or mating component in place and resists loosening under vibration
• 6-32 UNC thread for compatibility with standard tapped holes in small mechanical components
• Grade 18-8 stainless steel construction provides corrosion resistance in damp or mild chemical environments
• 1/16 inch hex key drive allows installation in recessed or flush-mount applications with no protruding head
• 5/16 inch overall length suits thin-wall hubs and close-clearance assemblies

Compatibility

Designed as a standard 6-32 UNC cup point set screw for use in any tapped hole meeting 6-32 thread specifications across general mechanical and light industrial assemblies.

Installation Notes

Installation requires a 1/16 inch hex key (Allen wrench). Ensure the mating tapped hole is clean and free of debris before threading. Tighten to snug engagement against the shaft or component surface without over-torquing, which can strip the small thread or damage the mating surface. Confirm the assembly is de-energized or the shaft is stationary before installing or adjusting set screws in rotating equipment.
