  PRODUCTS DETAILS: Stainless steel hex bolts are also called stainless steel hex screws, or simply called stainless steel hex bolts. Its material is stainless steel, is a hexagonal bolt made of stainless steel screw wire pier. Stainless steel hexagonal screws are stainless steel 201, stainless steel 304, stainless steel 316 and so on. Depending on the quality of stainless steel, the market prices are different, the better the material, the higher the price. Stainless steel outer hexagon screw is the most commonly used stainless steel fastener series, and nuts, used in the product has higher anti-corrosion requirements and surface finish requirements, stainless steel outer hexagon screw generally has two kinds of full teeth and half teeth, and half teeth products are divided into thick rod half teeth and thin rod half teeth. SUS304 and SUS316 are commonly used in the production of stainless steel external hex screw materials. Most of the stainless steel external hexagon screws in circulation are full teeth.
