Particle Board Decorative Self Threading Metal Screws For Thick Steel Right Hand Threads

1. Descriptions:

 

     Sheet metal screws have a pointed end and widely spaced threads. They're self-starting in thin sheet metal, but in thicker materials a drilled hole is recommended.

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are alloys of iron and carbon that contain between 16% and 30% Chromium, a maximum of 0.15% carbon, along with Nickel (or Manganese), and other alloying elements. The chromium, which helps develop a passive surface oxide film, provides corrosion resistance in stainless steels. Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316). Another common naming convention for Austenitic Stainless Steels are 18/8, 18/10, 18/0, etc. where the 18 refers to the % of Chromium and 8 to the % of Nickel contained in the material.

        Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material. Self-Drilling Points are excellent for use with sheet metal.

3. Applications:

         

       Self-drilling screws have hardened drill points that will drill and thread in structural steel, mild steel, aluminum and wood. These drill points are manufactured in the same method as the high speed drill bits. Self-drilling screws are available in a variety of finishes with unique product features to suit a wide range of environmental conditions.

  • For the fastening process in steel, they are used on steel frame construction or fastening other materials on steel.
  • For the fastening process in wood, they are used for applications in wood structures or industrial lightweight constructions, such as roof deck, flooring.
  • For the fastening process in aluminum, they are used for special industrial applications, construction and manufacturing of windows.
  • Widely applied for fastening in window or door frames purpose
  • Using in flat surfaces required and using in pre drilled holes.
