Couplemate recommends tightening nylocks with a socket. Important: Tighten nuts on the diagonals.
Rattle guns used on tightening u-bolts tighten too fast and can cause the nylon inside the nylock to dislodge. Rattle guns can also cause one side of the fishplate to become too tight, causing spring breakages at the centre bolt.
The Couplemate 1/2" Ubolt Galvanised Kit have even been treated to prevent hydrogen embrittlement. Here is an interesting article about galvanising.
