Bi-metal screw, an exceptional product of the advanced technique. The head and threads are made of stainless steel 304/316, providing perfect corrosion protection and ductility, The drill point is made of hardened carbon steel welded to the body.
A spiral point self-drilling screw is a type of fastener that drills its own hole and forms threads as it is driven into a material. What sets it apart from other self-drilling screws is its unique spiral point at the tip that helps to reduce the torque required to drive the screw and allows for fas
A decking screw is a type of screw designed for use with decking materials such as wood, composite lumber, or PVC. Decking screws are typically made of corrosion-resistant materials, such as stainless steel, and are designed to be long enough to penetrate the decking board and into the supporting jo
A stitching screw is a specialized type of self-tapping screw that is designed to attach two metal sheets together without the need for pre-drilling a hole. It features a sharp point, a narrow shank, and a wider thread, which allows it to pierce through the top sheet of metal and then thread tightly
Hydrogen embrittlement is largely unpredictable, and efforts to avoid it must start at the design stage to determine the characteristics of the part and the subsequent manufacturing process.Avoiding hydrogen generation during manufacturing and hydrogen absorption by fasteners eliminates the risk of
A4 is equivalent to American standard 316L stainless steel and equivalent to my country's 0Cr17Ni12Mo2 stainless steel. 0Cr17Ni12Mo2 austenitic stainless steel is suitable for use in seawater and other media. It is mainly used as a pitting corrosion resistant material. It is used in photography, foo
What is a dual hardness drill end screw?The dual-hardness drill tail screw is made of alloy steel, and adopts a segmented heat treatment method to make the bearing part of the screw have stronger toughness, and at the same time make the drill bit and threaded part have greater hardness to achieve st
NSSC550 (13Cr-2Ni-2Mo) is a product of martensitic (M) series stainless steel with high hardness and high corrosion resistance independently developed by Nippon Steel & Sumitomo Metal.Properly quenching and tempering this steel can obtain extremely high strength and hardness of 0.2% yield strength 1
1. Structure of composite screwThe industry usually uses SUS304/316+ high carbon alloy steel alloy steel for welding combination, the combination of composite stainless steel drilling screw has SUS304/316+SCM435/SS4202. Features of composite screwsThe composite stainless steel drill tail screw is a
Typical fastener hydrogen embrittlement occurs in carbon steel and alloy steel materials.The hardness of fasteners is a core parameter. When most standards talk about hydrogen embrittlement, they will point out that the risk of hydrogen embrittlement begins when the hardness exceeds 320HV. Some expe
