Tests confirm its effectiveness in arresting crack growth in A36 bridge steel.first-line of defense is to drill crack -arrest holes at the tips of a crack to blunt its fatigue propagation propensity. It is well understood that crack arrest holes are not a panacea for halting crack propagation in steel bridges, and that cracks often reinitiate after additional loading due to a Safest way to stop drill is to put the hole about one drill diameter from the end or the crack and let the crack move to the hole. #40 (3/32") is the common size. Back the plastic up so you don't shatter the other side and initiate more cracks. It's OK to fill the hole with sealant.Cut the plugs off about 1/16” above the surface and peen them.
