The 3/8-16 4-prong zinc t-nut is the best seller because of the price. It's the cheapest in our offerings and the most readily available. If installed and seated correctly, they work great. Below is a Pro/Cons list.
- Lowest priced t-nut from our line.
- Always available
- Good choice for indoor and outdoor walls.
- There is a risk of hammering them in crooked.
- When not hammered in enough, they can pop off the back. It would be best if you did not glue the t-nut to your panel. Spend time and install the t-nuts correctly. See below for installation.
- This model is less forgiving when you cross-thread a bolt in it. If the t-nut is not seated correctly, you can cross-thread the t-nut. You can push the t-nut off the back of the wall or even break the prongs on the t-nut. The advice here is always hand thread the first, bolt to the t-nut introduction, and then use a T-Bar Wrench with medium or large hold and tighten down enough so that the t-nut gets pulled into the wall. The result is a properly seated t-nut.
- Expert Tip: We seat every t-nut when the panel is one the ground. We use a large hold that has 1" or more of material behind the washer inside the climbing hold. We hand thread the bolt until we are satisfied we have achieved a proper bolt to t-nut threading. We then take an impact driver with a 5/16" Hex Driver Bit and run the driver mechanism enough clicks/bursts to seat the t-nut. If you hear the clicks/bursts from the impact driver for more than one second, about 5 to 10 clicks, you are most likely overdriving. It's doesn't take much to seat a t-nut using this method.
