Value Collection R40314441 Set Screw Cup Point 18-8

Product Description

The VALUE COLLECTION R40314441 is a miniature cup point set screw designed for precision fastening applications that require a flush or recessed installation. Threaded to a 0-80 UNF specification with an overall length of 1/16 inch, this set screw is manufactured from 18-8 stainless steel, providing solid corrosion resistance in light-duty mechanical and industrial assemblies. The hex drive accepts a 0.0280 inch hex key for installation. Its cup point geometry bites into the mating surface to resist rotational and axial movement without requiring a nut. Machinists, assembly technicians, and maintenance professionals install this fastener in applications where minimal footprint and secure clamping are required.

This set screw is suited for use in precision instruments, miniature mechanical assemblies, set collar retention, and light-duty shaft-to-hub locking applications. The 0-80 thread size and 1/16 inch length make it appropriate for tight-clearance installations found in electronics enclosures, optical equipment, and small-scale industrial machinery. The 18-8 stainless steel construction handles mildly corrosive environments and resists galling better than plain steel in comparable thread sizes.

Key Features

• Cup point geometry creates a firm seat against mating surfaces to resist loosening under vibration
• 18-8 stainless steel construction offers corrosion resistance for use in humid or mildly corrosive environments
• 0-80 UNF thread provides fine-pitch engagement for controlled clamping force in miniature assemblies
• Hex drive requires a 0.0280 inch hex key for installation and removal
• Overall length of 1/16 inch suits tight axial clearance applications

Compatibility

Designed as a standard 0-80 UNF cup point set screw for use in any application calling for this thread size, point type, and 18-8 stainless steel material grade.

Installation Notes

Installation is performed with a 0.0280 inch hex key. Ensure the mating shaft or surface is clean and free of burrs before seating the cup point. Apply only hand torque with the appropriate hex key to avoid stripping the miniature thread. Do not use power drivers on 0-80 thread fasteners, as over-torque damage is common at this size.
