Please provide some joint strength allowable data for a proper stress evaluation of the camloc 2600F series

Question:

Please provide some joint strength allowable data for a proper stress evaluation. Specifically, we plan to install 2600 & 2700 Series General Purpose quarter-turn fasts in various metals, like 2024-T3 clad aluminum, and 6AL4V Titanium sheet. Ultimate tensile strength is clear enough, but please define what you call "working strength". Is that a minimum guaranteed shear allowable of the Cam-Loc? Please reply.

Answer:

Here are the strength numbers for the 2600 series:

Ultimate strength: 1330N maximum tensile force, a permanent distortion is possible above the working strength which could cause the system to not operate correctly but will still be able to hold the two plates together until the maximum tensile force is reached, above this number the part will break.

Working strength: 900N max. recommended tensile force without any damage occuring

Clamping force: 34N-60N (depending on the range of the total thickness) above this the two panels will fall apart

Shear load: Quarter turns are not designed to handle shear load.

If you are performing tests, you will see in most cases that our values have a safety factor build-in, although we do not communicate this to our customers, it might occur that the part will break at 30% above the ultimate tensile strength.
