Bolt size:

Equals the washer designation. E.g NL6 washers fit with M6 bolt, NL1/2 fits with 1/2 bolt etc.

Washer material:

For a steel bolt use steel washers and for stainless steel bolts use stainless steel washers.

Washer outer diameter:

Washers with a standard outer diameter are the most commonly used, but if you have an enlarged or slotted hole, we recommend washers with an enlarged outer diameter (SP) for better load distribution.
