Based on my experience, these stainless nylon insert lock NUTS are an excellent choice for all your DIY projects. They are sturdy, easy to install, and offer great value for money. The nylon insert ensures a tight grip, and they are perfect for fastening parts that require a strong lock. They are also rust-resistant making them ideal for both indoor and outdoor use. However, the only downside I noticed is that they are a bit small, so be sure to check the size before purchasing..See full review
