sieze those shackles!

Vyv - what happens to Loctite in a pin when it gets hit by, say, being dragged along a stony bottom, please ? Does it set really hard and shear suddenly ?

I have never had one come undone. My anchor is attached via a Wichard countersunk shackle to three links of 10 mm chain, then a Kong swivel to 8 mm. The shackle and swivel have been loctited for about the past four seasons, renewed each spring. We anchor most nights for six months each season, so I guess the pins receive some abuse in that period. The one that holds the swivel together is probably most at risk, being a short, fat countersunk screw, but it has never moved.
