Timber spikes are specially designed in a way wherein they pin together two or more wooden entities. These are provided with semi-cone pointed fetter drive threads that can be driven well into timber just like a nail, thereby speeding up installation.
The head of the timber spike is huge and low profile, hence it provides a vast bearing surface ensuring the bolt does not pull into the timber. Fins or lugs present on the head’s base tend to bite into the wood, eventually preventing the timber spike that is installed from turning. BBI also supplies timber bolts – the bolt which has a national coarse thread.
Manufacturing
BBI manufactures top quality timber spikes. With a diameter of 1/2″ – 1-1/2″, these bolts fulfill most specifications of the ASTM, AASHTO, and SAE. Besides, we accommodate special request when it comes to heading, thread type, and finishes.
Standard Thread Length
The minimum thread length shall be equal to half the nominal spike length plus 1/2″.
