The most critical step in this seemingly simple fastening process is the initial tapping and cutting process. Whether the TEK screw can penetrate the plate and whether the drilling is rapid, these are related to the drilling point of the TEK screw.
DISGO is a special metal surface treatment technology. Disco is completely environmentally friendly and complies with the EU ROHS (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive). DISGO is a chromium-free ultra-thick film corrosion resistant surface treatment technology further developed for the phenomenon of hydrogen embrittlement caused by RUSPERT processing. After the surface treatment of the product, due to the protection of high chromium-free chemical oxidation solution, the occurrence of hydrogen embrittlement is avoided.
Stainless steel self drilling screws are divided into 304 stainless steel self drilling screws, 410 stainless steel self drilling screws, 316 stainless steel self drilling screws and so on.
