Ratings & Reviews for FastenMaster Collated Cortex for Royal Trim Screws and plugs White Hidden Deck Fastener 50 Linear feet ( 75 -Pack )

Works well

works well and fast, even looks good on the textured side of the trim. Just a little pricey but nice to be done with it quickly and not have to go back and putty up the holes.

Ease of install

Easiest way to install PVC windowsills, trim boards, etc. Wish everything was designed to work this easily.

Cortex Self Tapping Deck Screws

These screws are designed to install PVC and other composite Deck boards and work well with included caps to completely conceal the heads with colors which match Azek boards as well as white for appearance PVC boards. The only negatives are the price and frequency of breakage which requires pliers and persistence to remove the broken ones. Also the textured plastic caps are somewhat Time consuming to install after aligning the faux wood grain to match that of the deck boards with a rubber mallet...

Best thing going

I had always used PVC nails, with the special driver you will be able to sink the screws to the proper depth with no drilling. The caps fit in nicely but you have to cover them with some type of cloth when taping them in, in order to keep them clean. This product will be used on all PVC boards I use from now on in.

count your screws

I ordered 2 boxes and one of the boxes only had 55 screws when there was suppose to be 75. At the price you pay that was a big deal. Glad I counted.

They are expensive, but they work

I used these screws for 1" Azek boards, so they are way too long. That creates some problems, as the #1 square drive tends to ream out under high torque at the end of the run. I found that an impact driver fixed the problem by driving them cleanly. I was using up a square bit ever 4-5 screws until I switched and I finished the rest of the box with one bit on the impact driver. I just guessed the depth of countersink and that worked fine. The plugs work very well and are nearly invisible.
