Another weird and wonderful order was received recently for some 12 Point Flange Nuts and Screws in Black Oxide for the aerospace industry.The customer specified UNJEF thread which is a very unusual thread form. UNJEF are ultra fine pitch threads. The thread accuracy is referred to as a 3B class of fit or a 2B class of fit.Normally we take days to complete our standard jobs, but this part took 3 weeks due to its complexity.#engineering #fasteners #manufacturing​
