Fully Threaded Lag Screw: Wednesday’s Word(s) Of The Week

Although not standard, it is possible to special order lags which are threaded their entire lengths. Lead times and cost are significantly higher than standard lags. They are typically used as reinforcing within a beam, rather than for connecting parts. A common example is radial tension reinforcing of pitched and tapered beams made of species other than southern yellow pine.


*Wednesday’s Word Of The Week is a feature on Unalam’s Wood Times Blog. Each Wednesday our structural engineer, Rik Vandermeulen, will discuss a new term associated with glulam manufacturing. He will do this until we run out of words. If there is a timber or glulam term that you have heard of and want to know more about, let us know in the comments.
