Tips

Here are some helpful tips for you.

Select the bolt type according to the material. Most solar hanger bolts require a pilot hole.
Avoid using self-drilling solar hanger bolt on wooden profiles—they may cause damage to both the wood and the double thread rod itself.
Pairing with our nuts and washers significantly improves fastening strength and overall system stability.
For wooden structures, sharp-point coarse-thread solar hanger bolt are highly recommended. Choose ST8 for general use, and ST3/8 for softwood.

Notice & Tips Based on Experience

From our experience, minimizing the smooth rod length improves stability and prevents leaks.

Self-Drilling: Not for Wood Without Pre-Drilling

Heat buildup during installation may damage the wood and compromise structural stability

Choosing the Right Thread Length

Select the thread length according to your project. In Brazil, solar hanger bolts typically have a thread length of 70mm or more.

Place EPDM washer on the smooth rod, not on the threads.

To prevent water leakage.

Customization Options

For all custom double-thread rods, we recommend minimizing the smooth rod length, concentrating it only where the EPDM washer is placed. After installing the EPDM washer, the smooth rod should be ≤1 cm
