Hello, my father and I are currently building our garden shed. It is 2.5x2.5m. To the left of it, an extension (optional), also 2.5x2.5m, will be added.

For the roof support, two wooden beams are used, among other things, 4cm wide, 12cm high. These each protrude about 11cm from the garden shed itself. There, the roof frame or roof box will be attached.

Since I also bought the optional extension, two beams will again be flanged onto these two beams. These come each to the right, meaning they run parallel and share these 11cm, making them 8cm wide there.

According to the manufacturer, the beams should each be fastened with 2 carriage bolts. My father doesn’t like that so much. He proposes to use 2 threaded rods of 10cm each with washers and cap nuts. I find that basically okay.

My question is whether there is a complementary or generally better method to maximize the stability?

I find cap screws with hex nuts and washers better.

Alternatively, in my opinion, it is also possible with 2-3 screws 70*6 on each side.

Okay thanks. Castle screws also better than Spax full-thread screws, with a washer head in 8mm thickness and 8cm?
