To prevent crushing the wood laminate or fiberglass, we use large oversize "body washers". These are thin, flat washers that cover a surface area 2-3 times the normal surface area of flat washers. This allows proper tightening while distribuing the forces over a very large surface area hence reducing the local pressure that can cause cracks, etc. Best regards, Dr. D.C.
