thru axle

My goofy ah overtightened the original axle on my Boardman MTR 9.0 2021 medium, decapitated the poor thing... It's marked with: 20e3 qr52m-12-172-p1.5-12, I haven't been able to find a suitable replacement. I measured the axle at 174mm excluding the head, 12mm of threaded length, and a head...
