See the difference between machine screw and post and nut fittings.
With a machine screw post, you will not have a nut and post on the inside of a drawer. Machine screw fittings will come with screws for 3/4" thick wood. If your wood is thicker or thinner, please tell us in the note field.
A post and nut is a very traditional way to mount drawer pulls. If your furniture is antique, or you want it to look that way, you should consider using a post and nut. The post itself is 1-1/4" long. For most drawers you will need to counterbore and or cut the excess length off the posts once installed to get an ideal fit

Sustainability. We choose our packing materials with the planet in mind. We use popcorn and newspaper. The popcorn, made from cornstarch, is a harmless alternative to Styrofoam. It is completely biodegradable and dissolves in water. The newspaper we use represents the ultimate recycling. Our employees bring it in and we reuse it!
