Value Collection 93982 Cup Point Set Screw 1/2-13 Pack 25

Product Description

The VALUE COLLECTION 93982 is a cup point set screw designed for shaft-to-hub clamping and locking applications across a wide range of mechanical assemblies. Threaded 1/2-13 UNC with an overall length of 1 inch, this fastener is driven by a 1/4-inch hex key and seats with a cup-shaped point that bites into the mating surface to resist rotation and axial movement. Constructed from Grade 18-8 stainless steel, it provides solid corrosion resistance in environments where carbon steel fasteners are unsuitable. Sold in packs of 25, this screw is a standard solution for maintenance and production settings where reliable locking force is required.

Cup point set screws in the 1/2-13 thread size are commonly used in HVAC equipment, pump assemblies, fan hubs, motor shafts, and general industrial machinery. They are appropriate for both light and medium-duty clamping loads where a permanent bite into the mating shaft is acceptable. The 18-8 stainless steel construction makes them suitable for wet, outdoor, or mildly corrosive environments. Machinists, millwrights, HVAC technicians, and maintenance professionals install these fasteners as part of routine assembly and repair work.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• Cup point geometry grips mating shaft surfaces to resist rotation and axial displacement
• Grade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• 1/4-inch hex drive allows installation with standard hex key or Allen wrench tooling
• Overall length of 1 inch suits medium-depth engagement requirements
• Pack of 25 units supports production, maintenance stock, and field service needs

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw for use in any tapped hole or threaded assembly requiring that thread size and a cup point fastener.

Installation Notes

Installation is performed by threading the screw into a pre-tapped 1/2-13 UNC hole using a 1/4-inch hex key. Ensure the shaft or mating surface is clean and properly positioned before applying torque. Degrease contact surfaces when reliable locking force is critical. For mechanical assemblies in HVAC or pump systems, de-energize and lock out the equipment before servicing any rotating components.
