So, idiot that I am, I managed to snap my handlebar bolt. The bars kept slipping, so I got hold of a torque wrench and before hitting the right torque the bolt snapped. This is not a huge deal since I can get a new bolt and nut to replace the old one. My worry, however, concerns the stem and bars (both steel). Could I have damaged them in the process of overtorquing? Any way to find out?
do you see hairline creaks ? if no then everything is fine. you can crash the bar if you over do it.
should be just fine, as long as nothing was crushed. just get a new bolt and try again.
If both the stem and bars are both steel, there is almost nothing you could do the damage them. Gicv them both an inspection for distortion and cracks but if they pass, just get another bolt. If the original bolt failed at below the recommended torque it was probably corroded or otherwise damaged before.
