Ratings & Reviews for DeckForce by Grip Rite Deck Force #9 x 2-1/2-in Composite Deck Screws 742 -Per Box

Always predrill the hole for the screws at 1/8"

I used these screws for my Trex decking boards and was very pleased.

Pre-drilling works best

Goes in smooth

buy slightly longer than you normally would

the left hand threads at the top have a tendency to cause you to strip out a hole too easily, unless you buy them minimum 1/2" longer than an ordinary construction screw you would use for the same project. the threads also destroy composite if you ever try to back them back out once they've been counter sunk.. they look good though

Good decking quality

Small head counter sinks itself, easy to work with.

Noyhing

They did what they are supposed to do

Hard to grip

Often, the screw didnt grip very well. When I tried to take it out, it would just spin.

bad screws

The reverse thread creates more problems than help. These screws drive in and spin about half the time, every screw needs countersunk with a drill bit, waste of time. needs redesigned.

Doesn't sink well

These screws are hard to get started and do not countersink well. When they stop biting into the wood, they will not go any further and are almost impossible to back out. The T-20 bit is not very hardened. I plan to return.

The bit fit and drove the screws as intended

Grab material great

These are terrible

These are the worst Trex screws I have ever used. You have to pilot hole them and 50% of them strip out before sinking far enough into the board for the head to be flush. I strongly recommend against using these as they will slow your project down immensely.

Good quality product

Look for a different brand!

These screws are designed with threads that go in opposite directions to each other and cause numerous problems inserting and removing them. Why they designed them that way is beyond my comprehension!
