Self-drilling screw manufacturers
Self-drilling screw manufacturers
(OP)
Hello all,
I'm looking to source some self-drilling screw manufacturers. I currently know of ITW Buildex, Hilti, and Grabber. I am not looking for distributors (Grainger, Fastenal) since they buy from Asia and cannot provide shear/tension capacities.
Thanks!

RE: Self-drilling screw manufacturers
I contacted the manufacturer, ELCO, and within a week they had performed pull tests applicable to my situation and provided the results.
I`d definitely look into them.

They are the most readily available and satisfy many situations.

RE: Self-drilling screw manufacturers
wannabe! You have provided me with all I could need and more. Everyone else gave good answers too, but you took all the work out of it. Mike, I am not necessarily concerned with ICC reports. I just need manufacturer supplied shear and tension values of the screws. I will calculate strength based on AISI unless the ICC report gives significantly better results.
My new position is in cold-formed truss manufacturing, so I actually need to pick a screw (economically) that we will use rather than specifying a generic screw callout. Connected material will be up to (3) layers of 18 GA, 50 ksi steel. Thanks again everyone.

RE: Self-drilling screw manufacturers
Not sure I understand. Surely you have read ICC reports? ICC report capacities = manufacturer capacities.

RE: Self-drilling screw manufacturers
The ICC reports only have capacities for a few typical installation. Often times, higher capacities can be calculated using the AISI equations rather than using the closest thing in the report.
To calculate the capacity, the manufactures tested fastener strength is needed for limit states involving the actual strength of the screw. The fastener's strength typically doesn't govern until you get to thicker materials and/or using higher strength sheet metal. The evaluation report typically list the nominal strength of the fastener( Pss and Pts). These values can vary greatly between manufactures.

If you have tension coming from only one of the 3 plies of 18 ga, the nominal pull-out capacity can be increased linearly by 2.
