External causes produce stainless steel screw locking phenomenon: the stainless steel bolts are not carefully cleaned off the production line or saved in the process, directly on the production line results in a product with threads foreign body locking phenomenon occurs 302 for mechanical processing self-tapping screws and bolts. 303 In order to improve cutting performance, Zoucheng 316 stainless steel screws, type 303 stainless steel add a small amount of sulfur, 316 stainless steel screws for use bar machining nut. 304 is suitable for hot upsetting when machining stainless steel screws, bolts specifications such as long, large diameter bolts, they are likely to go beyond the scope of cold heading process. 305 is suitable for cold heading process when machining stainless steel screws, Qingzhou 316 stainless steel screws, such as cold forming nuts, hex bolts. 309 and 310, Wudi 316 stainless steel screws, they Cr content and Ni content higher than 18-8 stainless steel, stainless steel screws for high temperature work. Locking resolved first, the use of special materials rebound, such as engineering resin material, it has good rebound. Stainless steel screws to attach it tooth pattern. It with nuts, or mechanical friction material products. Vibrate and absolute resistance. Completely solve the problem of loose screw off. 316 stainless steel screws | Jinan Daoqin | Zhangqiu 316 stainless steel screws provided by Jinan Daoqin Trading Company. 316 stainless steel screws | Jinan Road ground | 316 stainless steel screws Zhangqiu Jinan Road ground Trading Company (www.daoqinshangmao.com) (www.daoqinshangmao.com) this year introduced a new upgrade, the above picture is for reference only, please dial this Tel pages or pictures on obtain the latest information, contact: Chuan-use.
