Stainless Steel Hex Head Screws are applied in installations with the help of torque wrenches, spanners or ratchets. Suraj Metal Corporation is a leading manufacturer and supplier of the different types of 316 SS Hex Head Cap Screws which are used in applications where the use of nuts is not necessary. The 316 material is an austenitic stainless steel grade that has high corrosion resistance and strength.
The M3 Stainless Steel 304 Hex Screws have different sizes denoted with the M marks. The 304 material has chromium and nickel in the composition. It is strong, corrosion resistant and is low cost. So it is used widely in applications. And the types vary such as SS Hex Head Wood Screws which are used in wooden applications. The wooden applications can be tightened well with hex head screws and the use of nuts is not necessary. The machine screws such as the 316 Stainless Steel Hex Head Machine Screw is used in many machine components and in different mechanical applications. The screws can come with different thread types. Based on different application requirements the types of the screws differ. Please feel free to contact us for more information on the 316 Stainless Steel Hex Head Screws and the different types with the prices.
