question on engineered wood fasteners

Recently I tried a TrussLok engineered wood fastener to put together a three piece GPlam. The fastener threads seemed to strip the wood before they really tightened. The threads seem awfully shallow compared to the shaft diameter. Has anyone else had this problem?

Greetings scubabill,
As a first time poster Welcome to Breaktime.
This post, in response to your question, will bump the thread through the 'recent discussion' listing again which will increase it's viewing.
Perhaps it will catch someone's attention that can help you with advice.

So now they're making screws out of engineered wood? I would think the threads would strip easily.

I've never used them, but you're right -- the threads seem awfully shallow.
Bill, are you using the Truslok brand made by Fastenmaster? I've used them with great success, you must use the right length of screw though.....for a triple (three 1- 3/4" LVL's) you need to use the 5" version which is only threaded on the last 1 1/2" of the fastener, this prevents the threads from acting as a "wedge" while being threaded thru the three members, so when the bolt gets to the last member the top portion of the bolt shaft has no threads in the first two members, hence it will not tend to seperate the members from each other.
I've found they work very well!

Exactly what I am using. Problem is that yu have to be extremely careful at end so that drill does not "over tighten" which then strips the wood by the threads. I would have liked to have seen a deeper thread vs shank size which problbly would have prevented the problems I had.

These are great.
