Stainless steel 304/316 hexagonal bolts and nuts, flat spring washers combination. Material: made of stainless steel 304 or 316. Stainless steel 304 has good corrosion and heat resistance and is suitable for general corrosive environments; while stainless steel 316 has higher corrosion resistance, especially excellent in marine environments and chemical media.
Following DIN933 (bolt standard) and DIN934 (nut standard), which are German industrial standards, ensures interchangeability and high quality.
Combination features: Hexagon socket head bolts used in combination with nuts and flat spring washers not only provide a reliable tightening force, but also increase the stability of the connection and the anti-loosening effect by means of flat spring washers.
