The product in question was a complete disappointment. Using this product, our team found that the nails were incredibly hard to insert and didn't hold well once they were in. The only positive aspect was that the nails were carbon-based, which helped to prevent rust. However, the poor performance overshadowed this one benefit. We had to ultimately switch to a different product to get the job done properly. Steer clear of this one.

I use small metric fasteners in my RC models. These fasteners work great and are durable. Inserts provide a strong connection to my control surfaces.

Ordered these nuts to replace wheels on my SCX24. They fit perfectly. The container is a bit difficult to open without spilling them, but it keeps them from getting enough sleep when they shouldn't.
