M16 Form 'B' Flat Washers Stainless Steel


M16  Form  'B'  Flat  Washers  Stainless  Steel
  • Form B flat washers are thinner than the heavier duty form A type washers.
  • They are made from stainless steel grade 304 (A2) or 316 (A4) for resistance to corrosion, and conform to BS4320 standards.
  • Washers provide a smooth surface for the nut or bolt to bear on, making it less likely to loosen as a result of an uneven fastening surface.
  • The main purpose of a washer is to distribute the load under a bolt head or the nut face.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties or steel and corrosion resistance are required.
