TERF® M8 (8mm) X 30mm Long Round Coupling Nut Female Threaded Bar Rod Studding Connector Round Deep Nut For Home Office Workshop Industrial Constructor and Multi Purpose Use - Pack of 10

These work great! I got the 8mm size ones to create my own attachments for an F-machine. I drilled holes into vac-u-lock suction cups then friction fitted these at the bottom to quickly attach toys to the device. It works perfect and saved me buying the quick connect attachments from f-machine which cost about five times as much! :) Good fit as indicated good and strong too.

Very well machined nuts

Very useful did what i needed with one proviso some of them the tapping on one end it at a slight angle made life a bit interesting but i managed to sort 2 perfect ones the external diameter seems very accurate across them all that was the important thing for me exactly 7mm OD solved to problem on my very old BSA Meteor MK2 air rifle no more barrel misalignment every time you break the barrel to loasd if

Very thin metal and it's for very light use. Photo of this post doesn't depict real thickness.
