DESCRIPTION

Spring Washer - Zinc Plate - 7/8x5/16 (Box=50)

(Price per unit)

Spring lock washers are flat washers that are cut and twisted into a slight spiral or corkscrew like shape.
  • When tightened, the washer flattens under load
  • If the bolt begins to loosen, the cut ends dig into both the bolt head and the contact surface
  • This biting action helps resist further rotation and loosening
  • They are widely used due to their simplicity and low cost
  • One of the most common and inexpensive types of locking washer.

Also identified as Spring, Split Lock, Grover, Single-Coil Spring Washers

Washers must be selected to match a compatible bolt , nut grade and material system to ensure proper strength and performance.

Finish
ZINC PLATED (RoHS Compliant)
 
Zinc Plated is the most common fastener of plating due to its the low cost and shinny bright silver finish. A thin layer of zinc is applied by either electroplating or mechanically. It is intended to be used internally. If corrosion is a concern, choose from the galvanised or stainless steel range for external use.
