Quick question concerning the required length of coach bolts... I'm
going to build a deck using 100mm support posts with 47mm joist
connected with coach bolts. Question is should I use 150mm coach bolts
or longer? Is the 3mm left over ample to tighten the coach bolt?
Counterbore the post to a depth of 1/2". If you want to be able
to dismantle this structure easily, grease (or dip in Waxoyl)
the bolts before fitting - they tend to rust in solid.
