Yea, these work. They are supplied with all of those cheap spike sets.
Of course, these go on the front of the panel, whereas t-nuts go on the back. This fine for mounting drivers, but if you are mounting panels to furring strips, the flange will cause an air gap. You will need to either use a gasket or countersink the flange. When I have used this type of insert, I use the unflanged, drill the clearance hole for the bolt, then redrill for the insert shank to the exact depth required. I have never had a problem pushing the insert through the furring strip.
Personally, I prefer the t-nut. As long as I take reasonable care to set the t-nut prior to use, making sure that the prongs haven't folded up under the flange, I've not had a problem with tear-outs. Of course, if you must torque the bolt down with a 1/2" drive t-bar....
