Titanium M10 studs
Here’s some M10 (x1.25) titanium engine mounting studs. Wherever possible it is usually a lot more economical to make engine mountings as studs rather than bolts with integral head. Thats because they are usually very long and turning 20mm dia bar down to a good tollerance and finish over that length is very hard and time consuming. But to put a couple of threads on stock 10mm bar is quick and easy so you save a lot on bar and time.
