I was reading "Stages to Saturn" a while ago and came across something I never heard about before to help reduce transient stresses caused by too much acceleration once the hold down clamps were released. Pretty amazing bit of engineering. More details in this thread I found:

So if I understand this right, at about the 1:33 point of the below video when the hold-down arms start to move, the pins attached to them are being pulled through dies.
Oops!. Looking at it wrong. The moving arms are just parts of the service masts. The one hold down arm is to the left and it looks like you can see one pin around the 1:58 mark.
