Value Collection R40342461 Set Screw 3-48 Cup Point 18-8 Ss

Product Description

The VALUE COLLECTION R40342461 is a 3-48 x 3/32-inch cup point set screw manufactured from 18-8 stainless steel. It features a hex drive socket and is threaded to the Unified National Coarse (UNC) standard. The cup point tip bites into the mating shaft to resist rotational and axial movement without requiring a protruding head. This fastener is suited for light-duty shaft-to-hub locking applications where corrosion resistance is a priority. Maintenance technicians and machine builders install these in precision equipment, instrument assemblies, and small-bore mechanical components where a flush or recessed fastener profile is required.

This set screw is used in applications requiring a small-diameter, fine-count thread with reliable holding force. The 3-48 thread size is common in instrument hardware, optical assemblies, small motor components, and light mechanical assemblies. The 18-8 stainless steel construction resists rust and mild chemical exposure, making it appropriate for both indoor and moderately humid service environments. This SKU is sold individually but carries a minimum order quantity of 100 pieces.

Key Features

• Cup point tip provides firm shaft engagement and resists loosening under vibration
• 18-8 stainless steel construction for corrosion resistance in general-service environments
• Hex drive socket accepts a 0.0500-inch hex key for installation in tight or recessed locations
• UNC thread standard ensures broad compatibility with standard tapped holes
• Headless design sits flush or below the surface of the mating part

Compatibility

Designed as a standard 3-48 UNC cup point set screw suitable for tapped holes conforming to the 3-48 Unified National Coarse thread specification in light mechanical and instrument assemblies.

Installation Notes

Installation requires a properly sized hex key — 0.0500 inches — to avoid rounding the drive socket. Ensure the mating tapped hole is clean and free of debris before threading. Do not overtighten; the small thread size is susceptible to stripping under excessive torque. Always verify thread engagement depth is adequate for the intended load before returning the assembly to service.
