Description:

Sheet metal screws have a pointed end and widely spaced threads. Theyre 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 surfoxide 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. Hex head fasteners can be driven with simple wrenches, and require minimal clearance above the fastener because they can be driven or loosened from the side. Self-Drilling Points are excellent for use with sheet metal. Features: Pointed end and widely spaced threads Stainless Steel is suitable where formability and cost are important considerations Hex head for easy driving Length is measured from under the head.
