why are coach screws called coach screws? These screws and bolts get their name from their primary function, dating back to the 1800s. These screws were used in manufacturing old-time wagons and coaches, more specifically, their wheels. They've been called coach screws as a nod to their former function!
Benefits of coach screws
Here are some of the key benefits of using a coach screw:
- Strength
Due to the shape of the shaft and hexagonal head providing compression, these screws are very strong. This means you'll be able to use a coach screw for parts of your project that see lots of use, such as joints or hinges.
- Resistant to force
Another great feature of this screw is that it's resistant to force. The unthreaded part of the screw (just below the head) gives it much more strength against brute force, meaning it's less likely to fail under extreme pressure. Consider using a partially threaded coach screw over a fully threaded coach screw for more critical parts of your project.
