Figure 8 fasteners provide a great way to attach solid wood tops to furniture bases. This is a method that’ll help ensure the solid wood tops you’re putting on your woodworking projects won’t crack as they try to expand and contract over time. Try them the next time you build a desk or table. They work equally well on tops made of man-made material, providing a rock solid method of fastening the top to the base.
