Product Description
Bi Metal Roofing Screw SS304+Ss410 Compound Self Drilling Hex Head Bi-Metal Screw
Product Description

  Bi-metal screw, namely bimetallic screw, is a kind of screw made of two different metals, usually combining stainless steel (such as SS300) and heat-treated carbon steel.

 

Materials
 
Stainless Steel Part: Usually, high-quality stainless steel materials such as 304 and 316 are selected.
Carbon Steel or Alloy Steel Part: The drill tail or tip part is made of high-carbon steel or alloy steel, which has undergone special heat treatment processes, such as quenching and tempering, to improve the hardness and wear resistance of the material.

 
Product Parameters
 
Diameter
The diameter of bimetallic hexagon composite self-drilling screws usually ranges from 2.9 mm to 6.3 mm, and common specifications include M2, M2.5, M3, M4, M5, M5.5, M6, M6.3, etc
 
Length
Its length varies according to specific requirements, ranging from several millimeters to hundreds of millimeters. Common length specifications include 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, 32 mm, 50 mm, 75 mm, 90 mm, 110 mm, and 125 mm, etc
 
Hardness
Different parts of the bimetallic screw have different hardness requirements. For example, the drill tip part made of carbon steel or alloy steel has a relatively high hardness after heat treatment, generally reaching about HRC50 - 60, so that it can smoothly drill into the connected materials
 
Tensile Strength
Common tensile strength grades include 4.8, 6.8, 8.8, 10.9, 12.9, etc
 
Surface Treatment
  • Electro-galvanizing treatment
  • Nickel plating treatment
  • Oxidation treatment
 
Product Advantages
 
  • Excellent Corrosion Resistance
  • Outstanding Drilling Ability
  • High-Strength Connection Performance
  • Diversified Design Options
 
Application

Construction Industry: In steel structure construction, it is used to fix components such as metal roof panels, wall panels, and purlins. For example, bimetallic composite self-drilling screws can be used.
Mechanical Manufacturing Industry: It is widely used in the assembly and maintenance of mechanical equipment, such as in the manufacturing of machine tools, construction machinery, mining equipment, etc.
Electronic Equipment Industry: It plays an important role in the assembly of electronic equipment housings and the fixation of circuit boards. Its small size specifications and good corrosion resistance can meet the high precision and reliability requirements of fastening elements for electronic equipment, while avoiding potential damage to electronic components caused by rust and corrosion.
New Energy Industry: With the rapid development of the new energy industry, bimetallic screws have also been widely used in fields such as solar photovoltaic and wind power generation.
