Stainless Steel Screws

Haiyan Jinrun Metal Products Co., Ltd. is a stainless steel screw manufacturer, can provide customers with a variety of stainless steel screws, stainless steel screw factory, the main types include stainless steel hex Washers head self drilling screws, stainless steel phillips pan head self drilling screws, stainless steel phillips countersunk self drilling screws, stainless steel modified truss head self drilling screws, stainless steel non-standard drilling nails, stainless steel self-tapping nails, etc. Standards in accordance with DIN7504K, American ASME standards, specifications from ST3.5 ST3.9, ST4.2, ST4.8, ST5.5, ST6.3, length from 13 mm - 150 mm, the material at present, the company production of stainless steel screws, mainly include SS410 and SS304, compared to carbon steel material, Stainless steel products have more advantages, mainly mentioned in the following aspects: 1, better toughness. Because the material composed of drilling nails is SUS410 material with low carbon content, this material can have better toughness after high temperature heat treatment, so it can effectively avoid screw breakage due to internal hardness of the product. 2, high strength performance. After the high temperature heat treatment, the surface hardness of the drilling nail is as high as HV580-HV750 or even higher, so that drilling and tapping can be accelerated, thereby improving the working performance. At the same time, it can better ensure the locking effect. 3, good corrosion resistance. Because its own material has good corrosion resistance, it has a longer service life than ordinary screws. 4, the appearance looks relatively clean and beautiful, low price stainless steel screws, can be customized stainless steel screws, free sample stainless steel screws, is the best choice for customers.


Due to the essential difference between stainless steel and carbon steel, stainless steel has good extensibility, and improper use is easy to lead to the screw can not be successfully penetrated, and the binding force is not strong. Therefore, in the use of stainless steel screws need to pay attention to: 1, before use to confirm whether the mechanical properties of the product meet the requirements of use. For example: SUS316 and SUS304 material screws can only enter plastic steel, magnesium titanium alloy, aluminum alloy, industrial plastics and other materials, such as SUS410C material drilling screws can not only enter the above materials, but also into stainless steel plate and various materials hardness at about HV300 degrees of steel plate. (steel plate below 18mm) 2, according to the use of the environment to choose different drilling screws. 3. Select different types and specifications of drilling screws according to different thicknesses of different materials. For example, when tapping thicker materials, choose longer drilling screws. 4. Keep the axis of the lock and the axis of the screw in the same straight line when attacking the locked object vertically.


The following explains the precautions for using stainless steel drilling nails with electric drills: 1. Stainless steel screws need special electric drills (recommended power 600W). 2. Adjust the positioner of the electric drill to the appropriate position to ensure that the screw is drilled to the correct position. Check drill speed: use 3.5(6#); 3.9(7#); 4.2(8#); 4.8(10#) 410 screws when; Ensure that the drill speed is 1800-2500 RPM; Use 5.5(12#); 6.3(14#) when 410 screws; Ensure that the drill speed is 1000-1800 RPM; Use 3.5(6#); 3.9(7#); 4.2(8#); 4.8(10#) when 304 screws; Ensure that the drill speed is 1500-2000 RPM; Use 5.5(12#); 6.3(14#) when SS410 screws; Make sure the drill speed is 1000-1500 RPM. 3, select the appropriate sleeve or cross head to install on the drill, and then connect the screw. 4, when installing the screw and the drill must be perpendicular to the surface of the steel plate, and click the power switch to create a central point. 5. Add about 13 kg of force to the drill by hand to ensure that the force is on the same vertical line with the center point. 6, turn on the power switch, can not stop halfway, and quickly stop drilling after the screw is in place (to prevent drilling is not in place and excessive drilling). The difference of Stainless steel 410 material and 304 material :First, the material is not the same: 304 stainless steel is a common material in stainless steel, the density is 7.93g /cm, high temperature resistance 800℃, with good processing performance, high toughness characteristics, is a universal stainless steel; 410 stainless steel is a stainless steel grade produced in accordance with the American ASTM standard, equivalent to China's 1Cr13 stainless steel, S41000 (American AISI, ASTM). Carbon content 0.15%, chromium content 13%, with good corrosion resistance. Second, the applicability is not the same: stainless iron drilling screw 410 can be heat treated, rust prevention ability is better than carbon steel, worse than stainless steel, you can drill iron; Stainless steel screw 304 can not be heat treatment, rust resistance, low hardness, can only drill aluminum plate, wood, rubber plate.
