- Serrated Conical Safety Washers Form / Type M have the unique feature of radial serrations on the convex surface. When final flattening of the serrated safety washer occurs with the tightening of the screw, the serrations bite into the mating face, thus preventing loosening of the screw caused by vibration
- Serrated Conical Spring Washers offer the following advantages:
They function much in the same way a serrated flange nut works, but as these are conical, they are pressed down into the surface as the fastener is tightened - Are Metric & Imperial Washers Interchangeable?: In most cases they are which is why we have added metric sizing to the imperial range and imperial sizing to the metric range. If you are still unsure or if the washer dimensions are critical click on the washer you are interested in and view the technical specifications table before ordering
- Material / Coating: Stainless Steel A2-70 G304 is the most popular grade of stainless steel. It is aesthetically pleasing to the eye and very practical because of its excellent corrosion protection in most environments. Due to the shape and design serrated washers are not stamped. Stainless steels are largely non-magnetic but it is common for some stainless steel fasteners, especially stamped components like washers to show a small degree of magnetism which is a result of work-hardening during the manufacturing process
- Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
