Metric Steel, Mechanical Zinc Plated or Zinc Flake Coated, Belleville Washer, "L" LARGE

Oversized Outer Diameter - Ribbed / "Rip Lock" Pattern

Belleville washers have a concave shape to maintain compressed tension. The Rip-Lock pattern on the top surface enhances the locking force and further prevents against loosening due to vibration or pressure.

Belleville washers can be used in tandem, one at the nut end and one at the bolt head end of the fastener connection.

Also known as serrated conical, coned-disc, cupped spring lock washer

Mechanical Zinc Finish

Anti-corrosive, approximately 240hrs salt spray, passivated.

Zinc Flake Finish

Zinc flake finishes are the environmentally friendly, VOC compliant replacement for Dacromet Coating. These finishes are water based with a chrome free coating that is anticorrosive and suitable for high temperatures, greater than 572 F. Zinc Flake finishes do not cause hydrogen embrittlement, which makes them suitable for high tensile fasteners. Salt Spray Resistance > 720 hours.
