Stainless steel outer hexagonal bolts are the most commonly used type of stainless steel fasteners, paired with nuts, flat washers, and spring washers, suitable for places with high anti-corrosion requirements and surface aesthetic requirements for products. Stainless steel outer hexagonal screws can be divided into full tooth and half tooth. Half tooth products can be divided into coarse rod half tooth A type and fine rod half tooth B type, as well as the selection of coarse tooth and fine tooth. Full tooth stainless steel outer hexagonal screws are threaded except for the head. The commonly used materials for producing stainless steel hexagonal screws include 201 stainless steel, 304 stainless steel, and 316 stainless steel. Dongguan Baolu Hardware Co., Ltd. is a professional manufacturer and seller of stainless steel bolts and screws. We can also produce special material bolts, such as SUS316L deep-sea corrosion resistant, SUS310S high-temperature resistant materials, SS2205, SS2207 duplex stainless steel chemical grade corrosion resistant materials, SS410 stainless steel, etc. Below, we will introduce the specific types and detailed distinctions of bolts:

1、 The universal standard DIN933 GB/T5783 for stainless steel hexagon bolts with full teeth is very similar, and the wrenches used for the heads with diameters M10 and M12 are different, while other specifications of wrenches are generally the same. DIN933 is a German national standard and currently the most commonly used full tooth bolt. Except for the standard number marked by the customer and shipped by our company, the default hexagonal full tooth bolt is DIN933. There is nothing that cannot be used in terms of performance or function. M3-M24 is basically available in stock, and our company has a super large production specification of M27-M72.

2、 Stainless steel outer hexagonal bolt half tooth: DIN931 GB/T5782 These two standards are thick rod A-type products, and the length of the thread is specified under different lengths.

1. The bolt length is less than 125mm, and the thread lengths are as follows: M6 18-23mm M8 22-28MM M10 26-33MM M12 30-38MM M14 34-39MM M16 38-43MM M20 46-50MM M22 50-55MM M24 54-60MM

2. If the bolt length is less than 200 and greater than 125mm, the thread lengths are as follows: M6 24-30mm M8 28-32MM M10 26-35MM M12 36-45MM M14 40-50MM M16 44-54MM M20 52-62MM M22 56-66MM M24 60-70MM

3. If the bolt length is greater than 200mm, the thread lengths are as follows: M8 41-44MM M10 45-50MM M12 49-55MM M14 53-60MM M16 57-62MM M20 52-60MM M22 69-80MM M24 73-80MM

4. B-type half teeth usually exist in 201 general stainless steel outer hexagon, and the standards are different. GB30-76 has the characteristic that when the bolt length is less than 60mm, it is full teeth, and when it exceeds 60mm, it is half teeth. The head size is the same as DIN9
