rockible Elliptical Machine Bolts Indoor for Exercise Indoor Bikes

Perfect, fixed my son's Echelon step machine! These were perfect! He's very happy! He's lost over 100lbs on that machine!

This thing is the reason that i can sweat now on resistance level 8.

Es el repuesto que esperábamos llego bien

These are cheapest steel possible with the outer one millimeter case hardened. The threads are cut into that case hardened surface so that there is barely any strength remaining. I replaced the original bolt after it broke after maybe ten hours of use. The replacement bolt didn’t even last two hours of use before it broke too. I am lucky enough to have a mini lathe and was able to cut a $5 American made bolt to replace it with. The left hand threads in the crank bar were very poorly cut from Sunny factory, so the replacement bolt I made has 5/16” threads with a nut on the inside of the crank bar. Lots of extra work but at least the bike works now like it should have if it had been built correctly.

ordered a pair to replace worn out bolts on exercise machine, one fit perfectly, the other does not screw in to lock nut. Not Tapped properly. Thank God it was dirt cheap...get what you paid for.
