We never pulled the hurricane tie until it broke. When we reached ~1000lbs of uplift I decided to not go any further. The CAMO Truss Screw broke at ~850lbs which is almost 300lbs over the specs. What’s your thoughts?
I failed a framing inspection due To the use of truss screws. The Local building inspector would Not approved the build without The hurricane straps. Soo... I used both. I believe he was Correctly following Michigan Code at the time. It may be Different now.
@@moredesignbuild I'm 74 and Haven't kept track of code since I retired in 2012. The instance I Referenced was in 2007. I used The screws after researching Their holding power and felt They would make code. They Didn't and I installed the Simpson Straps. I believe that at the time Screws were not permitted for Use on the straps. I'm glad codes Have changed. Great time saver.
@@billbertagnoli4226 Thanks for your story and interesting to hear. Finally we take small steps forward to improve and approve new techniques and products in the trades. Thanks for watching!
Simpson load values are the result of a safety factor of 3 being applied to the worst tested values. So in almost all cases you will get better than listed performance. Also, they are designed for a specific load duration. You basically did a sustained max load test.
10 screws going in perpendicular as opposed to one screw going in at a 45 degree angle. The result is what I thought it would be. I hate the task of installing straps but it is a good idea to do so.
I did look like the strap was further away from the screw giving more leverage than on the hurricane tie. It makes sense the tie would be stronger though, more steel.
There are different types of apps for the truss screws. You showed it in withdraw category not in sheer or toenail category. Simpson uses an on average ten to twenty reduction of their test results for their charts 4:06 .
Here in North Queensland I used 'triple grips', which are fixed in three directions, for both joists and roof purlins and rafters. They have held through three powerful cyclones, the worst being 'TC Larry', when one rafter split lengthwise. All timber is highest rated hardwood (46).
Then you don’t see the numbers. The truss screw holds more than it’s rated for and it also holds more than the straps are rated for. Yes, they break before the straps, but that’s not the point. Thanks for watching 😃

I got a lot of questions about this test and will do another one when I have time.
It’s always fun trying to break stuff.
Thanks for your input 👌🏽

I agree with you. If you live in a place where there are hurricanes/tornados! Way over kill anywhere else.
Fun with tests! More of this please!
More tests will come, that’s for sure!
Thanks for posting the link. Very impressed with the Truss Screw. You've earned a subscription and a follow 🎉

Good point! We did this just for fun but I think I need to do more testing like this.

Why would you use hardwood, it's brittle
@@jasonruff1270 30 species of termites in North Queensland.
@@treefarm3288 why not use treated wood then?
according to some, 8 hurricane straps per connection is better. OR....just build the entire house out of hurricane straps, leave out the wood.
😂😂
That screw didn’t have enough imbedded
I think I'll use both.
No need for both. You’ll pass inspection with one of them.
The screw was very low in the beam though. 4” down from the beam top gives you 3.5” penetration. Move that screw up me donut again 😂😂 nice job dude
Good point Kevin 👌🏼
I’ll do more tests but I’m still happy with the result. CAMO pass the test 🤘🏼😎
Do both (truss screw and hurricane) until failure.
I already have a list of different scenarios to test and your option is added to the list 👍🏼
Thank you…
You’re welcome
Truss screw also cleaner and saves labor
I totally agree 👍🏼
Wow really impressive. Truss screw for the win. For the price point ,ease of use and time.
Fuking awesome. I love hurricane ties. Could you retry the test with 10d Simpson sds screws vs the 9d that you used in this vid?? Thanks.
I’ll definitely do more tests like this! It’s actually really fun 😃
Yeah id rather use a tie all day long of a single or even double screw tie in
you'[[ stay with the truss screw and not the strap? 🤣🤣🤣🤣 Time and money instead of quality.......
