Ideal use cases
- Structural framing and support connections where high strength is required.

How to install and get the most from these screws
- Pair with appropriate nuts or tapped holes to complete through-fastening applications.
- Use a compatible hex driver or socket to achieve a solid seating without stripping the hex head.
- Couple with a washer in softer materials to distribute load and reduce pull-through, especially in structural connections or panels.
