What Customers Are Saying

Customers overwhelmingly praise these screws for exceptional performance on composite and wood decking, highlighting strong holding power, clean self-countersinking heads, and a flush finish that blends seamlessly. The T20 star drive head engages easily and resists stripping, while sharp threads allow smooth insertion with minimal effort. Many appreciate the color match and durability across outdoor projects. Some note the included bit wears quickly and recommend purchasing a higher-quality alternative. A few report hole stripping if driven too quickly or with insufficient screw length. Overall, most customers find them reliable and professional-looking despite minor technique considerations.

buy slightly longer than you normally would

Would Recommend

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.

Hard to grip

Would Not Recommend

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

bad screws

Would Not Recommend

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

Would Not Recommend

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.

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.

Look for a different brand!

Would Not Recommend

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!

Good screws for composite decking

Would Recommend

We bought these to go with composite decking. I expect them to far outlast the nails use in the previous deck floor.
