A timber spike is designed to pin two or more
wooden members together. The semi-cone pointed fetter drive threads
speed up installation because they can be driven into the wood like a
nail.
The oversized, low profile head will provide a large bearing surface,
thus preventing the bolt from pulling into the wood. Lugs or fins on
the underside of the head bite into the wood and prevent the installed
spike from turning. A
timber bolt, which is the same bolt only with national coarse thread, is also available.
Manufacturing:
Fastindo Wiratama manufactures timber spikes from 1/2″ diameter through 1-1/2″ diameter in most ASTM, AASHTO, and SAE specifications. Special request for heading, thread type and finishes can be accommodated.
Standard Thread Length:
The minimum thread length shall be equal to half the nominal spike length plus 1/2″.
