About Lag Bolts
Lag bolts, also called coach screws, are heavy screws with a hex head and a coarse, sharp wood thread. They are driven with a spanner into a pilot hole and give a strong hold in timber where a through bolt is not possible.
We supply lag bolts in zinc plated, hot dip galvanized and stainless steel for timber structures, decking, pallets and fixing equipment to wooden bases.
