Value Collection R40318426 Set Screw 10-32 X 5/16 in Cup Point

Product Description

The VALUE COLLECTION R40318426 is a cup point set screw designed for mechanical assemblies where a fastener must seat flush or below the surface of a workpiece. Threaded 10-32 UNF with an overall length of 5/16 inches, this screw is driven with a 3/32-inch hex key and locks into place using a recessed cup point that bites into the mating shaft or surface. Manufactured from Grade 18-8 stainless steel, the fastener resists corrosion in humid or wet environments. Machinists, millwrights, and maintenance technicians install this type of fastener in pulleys, collars, gears, and similar rotating or clamping applications.

This set screw is suited for light-duty mechanical assemblies in residential, commercial, and industrial settings. The 10-32 UNF thread pitch is common in instrument-grade hardware and precision sub-assemblies. The cup point geometry provides moderate holding force by indenting the mating surface, making it a practical choice for semi-permanent installations where occasional adjustment or disassembly is anticipated. Grade 18-8 stainless construction is appropriate for applications exposed to moisture, mild chemicals, or outdoor conditions where carbon steel would corrode prematurely.

Key Features

• 10-32 UNF thread with 5/16-inch overall length for compact fastening applications
• Cup point geometry bites into mating shaft for reliable holding force
• Grade 18-8 stainless steel construction provides corrosion resistance
• 3/32-inch hex drive compatible with standard Allen keys and hex drivers
• Headless design seats flush or below workpiece surface

Compatibility

Designed as a standard 10-32 UNF cup point set screw for use in any mechanical assembly, collar, pulley, or component that specifies a 10-32 headless set screw with cup point geometry.

Installation Notes

Machinists and maintenance technicians install set screws using a 3/32-inch hex key or T-handle driver. Ensure the mating shaft or surface is clean and free of debris before seating the screw. Do not overtighten, as cup point set screws can deform soft shaft materials. De-energize or lock out any rotating equipment before servicing fasteners on drive components.
