Value Collection R40324409 Set Screw 1/2-13 Cup Point Ss

Product Description

The VALUE COLLECTION R40324409 is a 1/2-13 x 1/2-inch cup point set screw manufactured from Grade 18-8 stainless steel. Set screws are headless fasteners that thread fully into a tapped hole and bear directly against a mating surface to lock shafts, collars, pulleys, and hubs in position. The cup point geometry bites into the shaft for strong holding power under vibration and torque loads. Driven with a 1/4-inch hex key, this fastener suits maintenance, repair, and assembly work across mechanical and industrial applications where corrosion resistance is a priority.

This set screw is used in general mechanical assembly, shaft-collar locking, and equipment maintenance in residential, commercial, and light industrial settings. The 1/2-13 UNC thread pitch is a widely used coarse-thread standard, making this fastener compatible with standard tapped holes in steel, aluminum, and other common base materials. Minimum order quantity is 100 pieces.

Key Features

• Cup point geometry provides firm bite and positive holding against rotating or sliding shafts
• Grade 18-8 stainless steel construction offers corrosion resistance in damp or outdoor environments
• 1/2-13 UNC coarse thread for reliable engagement in standard tapped holes
• 1/4-inch hex drive compatible with standard Allen keys and hex-bit drivers
• Overall length of 1/2 inch suits compact collar and hub configurations

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw for use in any application requiring a headless fastener with a 1/4-inch hex drive and 1/2-inch overall length.

Installation Notes

Installation requires a 1/4-inch hex key or Allen-type driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound if the application involves sustained vibration. Do not exceed the torque limits appropriate for 1/2-13 Grade 18-8 stainless fasteners, as over-driving can gall stainless threads.
