Theses little fasteners are very strong and work as advertised. You screw them in place, and they securely grab the grooved decking and hold it in place. What do you do if you can't tilt the next board to get the fasteners in the groove? This happened when the boards were under the frame of the slider and did not have enough space to tilt up. We simply had to loosen all the screws and then tighten again after the board was in place. We did have to watch the torque on our drills. This product worked well for us and gets a strong recommendation. Yes, they are expensive, but they definitely get the job done. Great service and support from Deck Expressions helped a lot
