Perfect for outdoor projects
Bought these for a garden trellis project. Since they are 304 stainless, I don't have to worry about rust. The anti-loosening feature works exactly as described.

Exactly what I needed
Fast delivery and the specs match the description perfectly. The flange diameter is generous which helps distribute the load nicely. Will buy again.

Excellent quality for automotive work
These locking nuts are fantastic. The stainless steel is thick and the nylon insert provides a very secure hold. I used them on my truck's exhaust manifold and they haven't loosened despite the vibration.

Reliable hardware
I run a small repair shop and we go through a lot of fasteners. These dragon caps are consistent in quality. The metal locking version holds up better under high heat than standard nylon ones.

Good value, slightly tight fit
Overall great product. The serrated flange grips well. The only reason for 4 stars is that the threading was a bit tight on the M8 size, requiring a bit more torque to start, but once on, they are solid.

Decent but packaging was poor
The nuts themselves are fine and seem durable. However, the box arrived crushed and some nuts were loose inside. Product is good, shipping packaging needs improvement.
Q: Is the flange serrated on both sides?
A: No, the serrations are located only on the underside of the flange to grip the mounting surface and prevent rotation. The top side is smooth for easy wrench access.
Q: What is the difference between the Nylon and Metal locking versions?
A: The Nylon insert offers excellent vibration resistance for general applications up to 120°C. The Metal locking version is designed for higher temperature environments where nylon might degrade.
Q: Do these come in imperial sizes like 1/4 inch or 3/8 inch?
A: Currently, this specific listing is for Metric sizes (M6-M20). We do carry imperial sizes in a separate product listing; please check our store catalog.
Q: Are these nuts suitable for use on a motorcycle engine?
A: Yes, the 304 stainless steel construction and high-temperature resistance make them suitable for motorcycle engines, provided the specific thread size matches your requirements.
Q: Can these be reused multiple times?
A: While they are durable, locking nuts are generally designed for limited reuse. If the locking element (nylon or metal) feels loose after removal, we recommend replacing the nut to ensure safety.
