    Let this help be a guide in your decision making.

    Factory specs may also have a procedure to test bolt stretch. Not all manufacturers may say the same thing. As always be thorough in your data acquisition.

    This is the first video I've seen in a little while that actually really peaked my interest, as I've been re-using TTY bolts for a long time with no found ill results. Interesting data points on the guys behalf. Very thorough and very informative. Great find Tor!
