What does DIN 985 refer to?

Question

DIN 985 is standard issued by the DIN in Germany.

In this case it is for a simple nut found here.

This is a follow up to this question from bicycles.

I Googled DIN 985 but found nothing comprehensible.

These nuts and bolts are to secure aluminum so I tagged this aluminum but if there is a better tag please edit.

DIN 985 appears to be the old name for what is now called ISO 7040 Which describes hex nuts with a nonmetallic insert, stating their dimensions etc.

If there a likelyhood of exposure to dampness I would reccomend using aluminium or stainless steel fasteners.

Can you provide a link that shows DIN 985 is the equivalent of ISO 7040 and break down what it covers? Thanks! – j.a. Jan 25 at 22:00

fasteners.eu/standards/DIN/985 indicates that ISO 7040 is an "equivalent norm" to DIN 985. Is that sufficient? – Doug Deden Jan 27 at 3:21
