DIN 6926 and ISO 1993
DIN 6926 is a legacy designation still widely encountered in purchasing documents and fastener catalogs. The current corresponding standard is DIN EN ISO 1993.
For RFQs specifying either DIN 6926 or ISO 1993, SENOTECH can evaluate the required dimensions, thread, property class and surface treatment before quotation.
Why Use a Flange Lock Nut?
