I am installing Veranda composite decking on my deck and plan on using the tiger claw hidden fastener system. Unfortunately the hidden fastener systems are very expensive. Do you think I could get away with using the tiger claw on maybe every third joist and gluing the rest (along with a “toe” screw from below). I think it should be alright but am not sure if there would be any adverse side effects from using adhesive. Any insight would be great. Thanks

Adverse side effect could be that the decking pops loose. Before doing this, maybe phone the decking manufacturer. Composite decking often has high % of polyethylene, which does not glue well. It also moves a lot with temperature, unlike wood which moves more with moisture.

I'd be shocked if that works. Composite decking moves a lot with temperature, but not moisture, and wood moves with moisture but not temperature. They will always be moving in opposite directions and will eventually break the glue bond.
But go ahead and try it. Maybe it will work.
Sounds like a good way to ruin some expensive composite. The stuff just doesn't glue well.

Do it right, or choose another method. You're gonna spend a bunch of money on a product designed to last a very long time in your choice of decking material. Use an installation method with both predictable and comparable results.
Several years ago I had a composite deck project than had a few decorative elements that required glueing - or so I thougt. I tried several types of glue and was unable to find any that I was not able to seperate after a week or so of curing... As noted above, gluing dis-similar materials (composite and wood) would be a "double wammy".
