Carbon Steel Nickel-Plated Cross Groove Headless Set Screws are professional mechanical fasteners, expertly crafted from high-quality carbon steel with a nickel-plated finish to deliver exceptional durability, corrosion resistance, and reliable performance for industrial, mechanical, and DIY applications. Designed as machine rice screws with a cone (taper) end and tightening top wire, these headless fasteners are engineered for low-profile, flush-surface fastening—ideal for securing mechanical components where a non-protruding, neat finish is critical.

 

Featuring a cross groove (Phillips) tip, these set screws allow for easy, efficient installation with standard cross-head screwdrivers, minimizing slippage and ensuring precise tightening. The headless design ensures they sit completely flush with the surface of the material, avoiding interference with moving parts, while the cone (taper) end and top wire provide a firm, secure grip on gears, shafts, pulleys, and other mechanical components, preventing loosening even in high-vibration environments.

 

The nickel-plated finish on the carbon steel base adds an extra layer of protection against rust, corrosion, and wear, extending the service life of the screws and making them suitable for use in indoor and light outdoor applications. Available in M2, M3, and M3.5 sizes, these machine rice screws offer versatile compatibility for a wide range of projects, from mechanical assembly and equipment maintenance to hardware repairs and DIY tasks.

 

Suitable for professionals, mechanics, engineers, and DIY enthusiasts alike, these nickel-plated carbon steel cross groove headless set screws combine functionality, durability, and precision. Whether used to secure mechanical parts, assemble industrial equipment, or complete detailed DIY projects, they deliver consistent, reliable performance and a clean, professional finish.
