DESCRIPTION

Spring Washer Square - Zinc Yellow Passivate - M4x7.0x1.2 (Box=200)

(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, square wire spring washer, rectangular-section spring washer

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