Think about it for a moment when you take a 2x4x16 and rest it on 3 saw horses spaced at 1 15 and 15 3 now apply a load in the middle of that 2x4 it bends off the last sawhorse.
Bolting deck beams to posts.
Don t rely on bolting deck beams to posts.
Post caps are sized for 4 4 and 6 6 posts at one end.
Bolting deck beams to the posts sounds like a good idea right.
Because the entire weight of the deck is resting on one of the members and that is being held by 1 3 bolts.
And it is as long as you re not solely relying on the bolts to hold your deck together and keep it solid and sturdy for years.
And over time the nuts and bolts you use are going to loosen.
The other end is sized for either a full 4x or 6x beam or a built up beam double or triple 2x.
Some can be installed after the post and beam are attached and are usually used in pairs one on each side of the post.
Since the size of the top is determined when the hardware is fabricated you have to order the correct size to match the beam size required for the deck.
There s no penalty for exceeding code and it s easier to keep a single bolt size on hand 1 2 inch bolts are required for many other deck connections.
Bolts alone are not going to secure those beams and posts together tightly enough.
