All of the Treehouse Attachment Bolts (TABs) that we offer are based upon the original design specifications by Greenwood Engineering in the Stud Tree Fastener (STF) diagram. Some versions such as the TAB 3x6HP and the TAB 6x9HP are larger, but the machining process and most of the other specs are the same as the original Treehouse Attachment Bolt (TAB 1x6HP) which is very similar to the STF. One difference is that ours are 4 threads per inch instead of 5, which installs faster and grabs the wood better. Please remember that our fasteners do not have weight ratings. The actual weight they will hold depends on the species of the tree, the tree's ongoing health, the distance the load is placed from the tree, the depth to which the collar is installed, whether or not the end of the fastener is backed up higher in the tree with a suspension system, and other design specific factors. Please consult with your professional engineer, arborist, or experienced tree house builder to ensure that you choose the right fasteners for your tree house project. Safety is #1.
