Clear Zinc Cr3 Plated Cup Point Socket Set Screws

Narrow Your Results By:

Clear zinc Cr3 plated cup point socket set screws are precision fasteners designed for secure, flush installation in high-performance mechanical and industrial assemblies. These set screws feature a hexagonal (Allen) drive and a cup-shaped point that bites into the mating surface, creating a strong hold without protruding. The cup point design offers excellent grip, making it the most commonly used style in set screws for permanent or semi-permanent fastening.

These screws are ideal for applications requiring a tight, vibration-resistant hold, such as in gears, collars, pulleys, shafts, knobs, and machine assemblies. Their compact, headless design allows them to be recessed below the surface, making them perfect for precision equipment and space-limited installations.

The clear zinc Cr3 plating (trivalent chromium) adds a protective layer that resists corrosion and oxidation. This RoHS-compliant coating is a safer, environmentally friendly alternative to traditional Cr6 coatings and gives the screw a bright, clean finish suitable for both functional and aesthetic applications.

Specifications include:

  • Drive Type: Internal hex (socket)

  • Point Type: Cup point

  • Material: Alloy steel

  • Finish: Clear zinc Cr3 plating (trivalent chromium)

  • Standards: ASME B18.3, RoHS compliant

  • Sizes: Common sizes range from #4-40 to 1/2-13 and metric equivalents

Whether you're assembling motor components, securing rotating parts, or aligning mechanical elements, clear zinc Cr3 plated cup point socket set screws deliver strength, precision, and corrosion resistance. Their versatile design and dependable performance make them a favorite in both industrial maintenance and OEM manufacturing.
