Stainless Steel Machine Screw, Flat Head, Phillips Drive, #0-80, 1" Length (Pack of 100) Reviews
Stainless Steel Machine Screw, Flat Head, Phillips Drive, #0-80, 1" Length (Pack of 100) Feature
- Machine Screws are often used with nuts or driven into tapped holes
- Stainless Steel is suitable where formability and cost are important considerations
- Flat head style allows fastener to sit flush to the surface
- Phillips drive is designed to cam out under too much torque
- Fine threads tap better into harder materials and thin walls, and are stronger in tension than coarse threads
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.
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Fine threads are preferable when working with harder materials or when threading into a thin material. They are also stronger in tension than coarse threads, and generally provide higher shear strengths.
