Product information

Stainless steel countersunk head screws with inch threads (or hexagonal threads) are screws with a flat head that recesses into the workpiece. They typically have a hexagonal hole and require a wrench to tighten. Their main properties are strength, durability, corrosion resistance, and rust resistance. They are ideal for automotive assembly, industrial machinery, and applications requiring a neat and clean finish.

Stainless steel material: Corrosion resistance, rust resistance, and durability.

Smooth countersunk head: The underside of the screw head forms an angle of approximately 82 degrees, allowing the screw head to recess into the material when tightened, creating a neat and clean finish.

Thread: Available in both full and half threads, depending on the application.
Tightening: Use a hex wrench to tighten, providing excellent torque resistance and a secure hold.
Common Uses: Stainless steel countersunk head screws with inch threads are commonly used in a variety of

applications, including:

  • Automotive assembly
  • Electrical appliances
  • Industrial machinery
  • Various installation and installation projects requiring a neat and clean finish.
