Frequently Asked Questions
What do the strength grades / classes denote?
- The grade or class of a washer denotes its strength & compatibility with the respective nut / threaded rod / screw / bolt.
- The higher the grade, the higher the strength of the fastener.
- SAE grades are used for Imperial washers. Washers having the same SAE strength grade as other fasteners should be used together.
- ISO classes are used for Metric washers. Washers having the same first digit as a fastener are meant to be used together.
- ASTM grades are based on factors like strength, pressure & temperature.
How to install a tension / load indicator structural washer?
A tension / load indicator structural washer can be installed on a bolt assembly while taking care that the washer does not come in contact with the rotating surface of the attached nut or bolt head. Coming in contact with a rotating part would cause premature compression & wear on the ridges of the washer and render it useless.
