No, I wouldn't expect so. I've used Squire closed shackle locks in the past with my Almax chain for locking up motorbikes. The nice thing a 19mm chain with the Squire lock is that the shackle is locked into position on the inside of the chain link and the profile of the link prevents the lock from being rotated to attack the shackle easily. These days I use an Abloy PL 342. It doesn't fit the chain as well, but I can see from marks on the shackle that it has resisted bolt cutters.
