This 4-prong T-nut is perfect for hanging bolt-on rock climbing holds to a home climbing wall.

- Designed for 3/4" plywood
- 3/8" x 16 (7/16" barrel length)
- Zinc
- These are the most affordable t-nut and most popular for home rock climbing walls

If a piece of plywood is horizontally laid out and you drill your holes in 5-inch patterns (a bolt hole every 5 inches), you will have roughly 19 columns of 9 holes = 171 (approximate) holes in a 4' x 8' piece of plywood. This can help you determine how many t-nuts you need. A 4" pattern results in 24 columns of 11 rows = 264 t-nuts per sheet of plywood.

To install: Drill a 7/16" hole, preferable using a Drill Guide for straight holes, from front to back of a 3/4" sheet of plywood in your desired pattern. Then, install the t-nuts for the backside, with the threads facing the front of the plywood. Most people will hammer them into the holes, but you can also use a scrap 3/8" bolt and a climbing hold to install them one at a time. This seats the t-nuts in perfectly each time but will eventually damage the hold. So use your least favorite hold if you do it this way!
