Default Left hand thread bolt.

Hi
I'm hoping that there is someone in engineering that can help. It's a little off-topic, but I need a left-hand threaded bolt 7mm dia and 20mm in length. I couldn't see anything on the web and ended up having to order from China. I received my long-awaited bolt today and it's, unfortunately, the wrong size. Think I ordered an M6 20mm bolt. It's a Screwfix shredder blade holder. Beware with their equipment : this is the second time I've been unable to get spares, last time it was a lawnmower part..

Try a company such as https://www.allfix.co.uk/
or https://www.spaldingfasteners.co.uk/about-us/

you may well need a professional nut and bolt company, not one such as Screwfix

Spalding fasteners look good - I ordered their left-hand threaded bar and nuts. Good postage amount too! Many thanks- it's a bit closer than central China!!

M7 and LH thread is more than a bit unusual IMHO. Are you sure of the thread dia.?
