China Stainless steel hexagonal head bolt Factory

Through our efforts over the years, jiaxing aoke already become a Aluminum Open End Blind Rivet manufacturer and supplier of fasteners in China. Export blind rivet in large quality each year. Warmly welcome to visit our company and build a long term relationship.

Jiaxing Aoke Trading is a professional manufacturer and supplier of fasteners in China. Our factory is jiaxing Aoke hardware which located in Haiyan county, which has a long long history for fasteners production. DIN6912 hex socket thin head cap screws with pilot recess is our newly developed product. The special point is having a hole in the hex socket. In order to open up new market demands, we put a lot of effort into developing DIN6912. The introduction of advanced equipment, the use of cold heading technology, better product performance, greatly improve production efficiency and reduce the production cost. Therefore, we have competitive price and high international quality.

BI metal self drilling screw is our newly developed product. It belongs to the solar photovoltaic installation accessories, widely applied in the aluminum profile and steel sheet. Jiaxing Aoke Trading is a Chinese professional manufacturer and supplier of solar fasteners. The BImatel drilling screws are made of two different material, stainless steel and harden steel (A2+SCM435). Therefore, BImatel drilling screws has the excellent corrosion resistance of stainless steel screws and the high penetration of carbon steel screws. Size 5.5x25 and 6x25 are wide used in the solar PV system roof mounting. Factory price and free samples for you.

EPDM stainless steel bonded washers are essential components used to seal self drilling screws installed on the roof for waterproofing. The grey EPDM washers from AOKE which made from grey ethylene propylene diene monomer (EPDM) rubber and stainless steel A2 A4. These washers offer excellent resistance to weathering, ozone, and UV exposure. Their high elasticity and flexibility ensure a tight seal, preventing leaks and providing reliable performance. Their durability and resistance to corrosion make them suitable for both indoor and outdoor applications. With the advantages of our own plant jiaxing aoke hardware, we can provide a wide range of samples and produce washers of any size you want.

Jiaxing Aoke hardware as the professional manufacturer in China, we would like to supply you conical washers. NFE25511 French anti-loose conical washers, also known as CS washer, NFE 25511 conical contact washer or spring disc washer. The surface is knurled, the core of its design is the conical structure and knurled surface. The conical structure of the washer generates elastic counterforces during the tightening of the bolt, and reducing the risk of loosening caused by material settlement. The knurled surface of the NFE 25511 French anti-loose conical washer increases the friction coefficient, preventing thread loosening due to vibration or thermal expansion and contraction. NFE25511 French-type washers come in three specifications: Z-type (narrow), M-type (medium), and L-type (wide). AOKE produces M3-M20, in various carbon steel grades such as Mn65 and stainless steel grades such as SUS304 (1.4301) and SUS316 (1.4401). The stainless steel material undergoes austenitic hardening to achieve the required mechanical properties and hardness.

As the professional manufacturer in China, Jiaxing aoke would like to provide you DIN7980 spring washers. You can rest assured to buy lock washers from our factory. DIN7980 spring lock washer is the German Industrial Standard for "Spring Washers for Cylinder Head Screws." Compared to the commonly used DIN127 spring washers, DIN7980 spring washers have a smaller outer diameter and are specifically designed for use with DIN 912 hexagon socket head screws. Why are we choosing stainless steel to produce DIN7980 spring lock washers? Stainless steel 304 (A2)/316 (A4) stainless steel offers corrosion resistance levels that cover atmospheric, freshwater, mild acid and alkaline, and marine environments. Stainless steel DIN7980 spring washers have a bright surface, require no electroplating, eliminate the risk of hydrogen embrittlement, and are RoHS/REACH compliant.
