410 Stainless Steel Countersunk Head Self Drilling Screw

*Material:410 stainless steel

*Gauge:10

*TPI:14

*Length:19mm,25mm,32mm

Advantage Of 410 Stainless Steel Self Drilling Screw:

*Surface hardness is HRC55-65, core hardness is HRC40-45.

*The characteristics of 410 material are that it rusts quickly and corrodes slowly. The corrosion rate is only 1/150 of ordinary carbon steel. It is not as same as the rust of carbon steel., the rust of 410SST is floating rust, which rusts quickly and further rusts very slowly. Therefore, the floating rust of 410SST will not affect the mechanical properties of the product within a certain period of time. In order not to arouse doubts of the user about the appearance , it is recommended to use 410 coated screws, which can reach longer service life.

*Stainless steel plates and various steel plates with a material hardness of HV300 (plate thickness below 18mm), and materials with a material strength above Q345 and below Q550. It is recommended to use 410 stainless steel coated self drilling screws.
