A family reference for specification-controlled hardware. Identify the relevant series and the details needed to source the required part.

// DIMENSION GUIDE

Washer inside diameter, outside diameter and thickness

Washer inside diameter, outside diameter and thickness
D is outside diameter, d is hole diameter, and t is thickness. The face view is on the left and the edge view is on the right.

Schematic only; not to scale. Letter labels are keys for this illustration. Use the applicable part specification for dimensions, tolerances and measurement conventions.

// IDENTIFICATION

Identify the washer function before comparing size.

Flat washers, tooth lock washers and helical split lock washers perform different roles. A common nominal screw size does not make these types equivalent.

AN960 and NAS1149 have a documented standard relationship. MS35333 and MS35335 are different tooth-lockwasher families; neither is simply a renamed flat washer.
