I'm going to be installing a decoupled ceiling into wood joists. The system comprises of clips that each take 4 screws. Each 1.2m x 1.2m 36kg plasterboard will be attached to 12 of these clips total.
Have some SPAX yellox 5.0 x 50mm.
Can't find any info online of shear strength of this specific screw or in general on this type of screw. The screws look pretty tiny for this job, but 5mm is the max diameter of screw that can fit through the metal on the clips. The way the L-shape clips attach to joists is such that the screws will be under sheer load.
Just want to make sure that the clips aren't going to shear off the joists when under load. Thanks for any help.
UPDATE/EDIT: thanks for replies. I'm going to use M5 HEXAGON HEAD COACH SCREW, STAINLESS STEEL A2, and I assume they'll also easily handle the shear load same as the SPAX ones.
