Domino Connectors - Torque Spec
« on: September 19, 2017, 06:53 PM »
Is there a spec for how much torque should be applied to the set screw (hex screw) of a connector ?

I cannot quote a specification, but I am using the corner connectors on a bed building project.

I found that if you exactly follow the instructions and make the mortises exactly as specified, the connectors pull the two pieces together without much tightening of the set screw. My bed rails are 4.74" high and 1.50" thick. I used one 14mm Domino and one connector per corner. The touchy part was getting the two rails tapped together close enough for the set screw to engage the chamfered hole but not too far in. Tightening the set screw visibly draws the two rails together. I tightened the set screw until the two rails were tight together but I didn't crank hard on the set screw.

The joint seems to be surprisingly sturdy.

I really like the connectors and hope Festool comes out with one that works with 3/4" wood.

That's not something that we have a spec on.

Thanks to @Birdhunter for posting his experience with them. If other's have insight based on using the connectors, I'd love to hear it.

Let me say that I've not had the opportunity to use these new connectors. But, it seems that it's just an expanding-style fastener. A torque spec wouldn't work since the torque would increase as the fastener opens and then it would drop off as it gets fully expanded.

So, drive it home to make sure that it's fully expanded. Obviously, don't cam it out. Just my 2 cents.

@Phil Beckley can probably also offer some advice.

@Shane Holland That's funny. "Well, just don't cam it out" is exactly what Rick said when I asked him.

Hi
With the hex key supplied you will find it very difficult to strip the bolt.....if ypu use a longer one then there is a chance. Tighten it until it is tight and alle good.....after to put it mildly many, many demonstrations I haven't cammed out any of the connectors  [cool].
. The connectors are great and as such my new Kitchen table is to be done with these....amd tel Rik amd Shane I taught them all  [big grin]

In reading these posts, I realized there are two answers to the question and I only answered one.

The connectors have two screw together operations. One expands the anchor and one draws the two boards together.

When I expanded the anchor, I felt quite a bit of effort was required until the anchor was fully expanded and then the effort decreased a lot. The two page instruction sheet is excellent in showing the mortise locations and depths. It’s also excellent in showing what a correctly set anchor looks like. The first time I set the anchor, I did not have the bolt screwed in all the way and the instructions sheet clearly showed the error I made.

I explained my experience in setting the screw that draws the two boards together in my first post.

It’s a really good idea to practice on scrap knowing the anchor CANNOT be extracted once expanded. My practice was just to cut the mortises and see how the mechanism worked without expanding the anchor.

Talking Saturday to a reliable source, he mentioned that Festool will be bringing out connectors soon that work with the DF 500...didn't know what size but at least that's a start. [thumbs up] [thumbs up]
