Stainless Steel Machine Screw, Flat Head, Tamper-Resistant Drilled Spanner Drive, #8-15, 1-1/4" Length (Pack of 50) 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
- Prevents tampering by requiring special tool to remove
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. Loosening tamper-resistant fasteners requires rare tools that the average user is not likely to have on hand, often preventing vandalism, theft, or product modifications by untrained users. Although not impossible to obtain, drivers for tamper resistant screws are rare and usually more difficult to find.
