An idea brought to us by Chris Becksvoort, the well-known Maine author/craftsman, these expansion washers are a creative answer to the problem of the cyclical expansion and contraction of solid wood panels and table tops.

They solve the ever-present problem of wood movement in furniture construction. Two sizes are available for use with round-head screws up to #10 or #14.

The washers readily install in skirts or frames; simply rout or drill the necessary slots in the members. The #10 is just shy of 1/2" wide with a 3/16" clearance slot, and the #14 just under 5/8" with a 1/4" clearance slot. They are an elegant and inexpensive solution to an age-old problem. Sold in packs of 12. Zinc-plated steel.

Made in USA.
