Can I use a quarter turn imao product with my wood boards?

Can I use a quarter turn imao product with my wood boards?

Question:

I am looking for a heavy duty solution that would allow for quick and easy deployment of a removable wheelboard.

Preferably with the receive receptacle mounted flush in the board.

The pin would have to work through 9mm or larger of wood and or aluminium extrusion.

 

Ideally the same fixing would allow us to remove wheelboards from racks and pin two racks on top of each other securely.

 

Dealing with weights in the region of 60-80kg for a fully loaded rack.

Probably with four fixings per board, 1 per corner.

 

 

Answer:

Typically quarter turns or imao products are not used into wood.

You should realise that it would be also better to mount a metal plate on the wood, so that with frequent use, the studs do not pull through your wood, and get non-usefull

There exist threaded receptacles but I do think that pricing will be outrageous for what you need. (10 to 100 more then if you take a standard flat receptacle)

 

 

If you can mount a standard receptacle at the back of your plate that would be ideal

It could be you can also mount at the side a clip on receptacle

Please forward your panel thickness dimensions

What quantities are you looking for, so I can immediately quote you

Would you need a stud that is operated with hand or a with a screwdriver?

 

Regarding the imao parts:

has only a tension load of 500 Newton = 50kg

so not enough

the larger version does the job, and has a receptacle that is flush.

(I would then go for the biggest, but you need to be able to mount your screws to install the stud into metal and not wood.

Please confirm if this is possible, there might be also issues if your wood is not hard enough when you install it into wood.

The load is 5kg which is mounted on a linear actuator that accelerates very quickly (a motor delivering 4G) can QCTH clamps be a solution?

The load is 5kg which is mounted on a linear actuator that accelerates very quickly (a motor delivering 4G) can QCTH clamps be a solution?

So real lateral load would be  5x 4  x 10 = 200 Newton

 

recomendation from the factory:

The shear strength of QCTH is 1800N / 3200N and the clamp does not remove because the pin contacts the inside of receptacle.

So I think it will work fine in his application.

I do not recommend QCPC because the clamping force and shear strength are lower than QCPC.
