Screws for trex deck

Very good screws that match my material well

Eric Bjorkstedt
Mixed bucket

These screws were perfect for my need (deck construction)… at least those that worked. A substantial fraction had shallow or malformed heads (driver bit would not seat cleanly) and a separate fraction were bent coming out of the bucket—perhaps casualties of rough handling during shipping? If I didn’t catch these misfits immediately (and it took some time to catch the pattern), it was easy to get snared in a skip-n-strip or even a time-wasting screw extraction. Rough estimate: a 10% failure rate. The screws that were well formed worked like a charm.

Thank you for taking the time to provide us with a review. We are sorry to hear that some of these screws did not function properly. Quality of our products is very important to us and we would like to bring this to the attention of our quality department. Please email your order number along with pictures of the product you received to customerservice@fastenersplus.com and we can work with you on a resolution. We look forward to hearing from you and working together on a resolution.
