Value Collection 2-SC-50C-100 Set Screw 1/2-13 X 1 in

Product Description

The VALUE COLLECTION 2-SC-50C-100 is a 1/2-13 threaded cup point set screw machined from Grade 316 stainless steel. At 1 inch in length, this headless fastener seats flush within a tapped hole and uses its recessed cup point to bite into a shaft or mating surface, resisting rotation and axial movement without the need for an external head. The hex drive socket accepts a standard hex key for installation and removal. Grade 316 stainless provides superior corrosion resistance compared to 304, making it well-suited for wet, chemical, or marine environments. Installed by machinists, millwrights, pipefitters, and maintenance technicians across a wide range of industrial and commercial applications.

This set screw is used wherever a shaft, collar, pulley, gear, or similar component must be secured to a shaft without a protruding fastener head. The cup point design is among the most common for general-purpose holding, as the point indents the mating surface for positive grip. Typical installations include shaft collars, motor couplings, valve handles, and adjustable mechanical assemblies in processing, marine, food-service, and chemical plant environments where stainless fasteners are specified.

Key Features

• Grade 316 stainless steel construction for strong corrosion resistance in harsh or wet environments
• Cup point geometry bites into mating surfaces for reliable axial and rotational holding force
• 1/2-13 UNC thread size for compatibility with standard tapped holes in that thread family
• 1 inch length provides adequate thread engagement for medium-duty shaft retention
• Hex drive socket works with common hex keys and Allen wrenches
• Bright uncoated finish — no added coating that could affect dimensional tolerance or chemical compatibility

Compatibility

Designed for use in any tapped 1/2-13 UNC hole requiring a headless cup point set screw in Grade 316 stainless steel. Typical fitment includes shaft collars, couplings, and mechanical assemblies that specify a 1/2-13 x 1 inch headless fastener.

Installation Notes

Installation is performed with a hex key sized to the socket drive. Ensure the tapped hole is clean and free of debris before threading in the screw. Do not exceed the torque capacity of the hex socket — stripped sockets are a common result of over-driving set screws. Refer to applicable mechanical standards and engineering specifications for proper seating torque and shaft surface preparation.
