The Stainless Steel Cross Recessed Pan Head Screws with O-ring , which have excellent waterproof and sealing properties. They are suitable for scenarios requiring moisture-proof, waterproof and corrosion-proof, and are applicable across multiple industries. Our company offers a variety of specifications for you to choose.

The density of aluminum alloy material is only one-third of that of steel, which can significantly reduce the overall weight in large structures. The surface of aluminum alloy naturally forms a dense oxide film, which, combined with anodizing treatment, can resist salt spray testing for more than 1000 hours, far exceeding the 500 hours of stainless steel. The conductivity of aluminum alloy is 4 times that of steel, and its thermal conductivity is 2 times that of steel, effectively avoiding loose connections caused by differences in thermal expansion coefficients.

The head is disc-shaped, with a diameter 20% -30% larger than the threaded section, effectively dispersing pressure and avoiding deformation or cracking of the connected surface due to excessive local stress. The head comes with a gasket, eliminating the risk of loosening in vibration environments and improving fatigue resistance by more than 50%. The groove design balances high torque and anti slip performance, making it suitable for electric screwdrivers and manual tools.

The surface of Nickel Plated Chicago Bolts has undergone nickel plating treatment, and the nickel layer has good chemical stability, which can effectively resist the erosion of air, moisture, and various chemicals. Ordinary metals may quickly rust in humid environments, affecting the connection effect and structural stability, while nickel plated mother nails can remain smooth and new for a long time.

The Truss Head Machine Screw adopts a unique head design and has a large flat shape, endowing the screw with many advantages. It is widely used in many fields such as industrial production, construction installation, furniture manufacturing, and electronic equipment assembly. The Head of the Truss Head Machine Screw is large and flat, which can provide a wide support surface, effectively disperse the pressure and prevent the material from being damaged due to excessive local force.​
