ASTM A194: Nut Grades, BS970/DIN Material Equivalents and Mechanical Properties
ASTM A194 (latest revision A194/A194M‑26) is a standard specifying carbon, alloy, and stainless steel nuts in sizes from 1/4-4" and M12-M100, which are intended for high‑pressure or high‑temperature bolting applications.
Please note that sometimes it is not possible to get exact chemical matches for material between ASTM specifications and British Standards. As we manufacture in the UK and source our material locally, mechanically equivalent material may be substituted - we will confirm that with you at the quotation stage.
