A:  Thank you for your question. We would recommend using Stainless Steel fasteners if this application is at a saltwater location. Two HeadLOKs are required for this connection in addition to a joist hanger at each joist end. Contact our website for more information.

            The Picture Says it All
            Purchased a pack of 50 of these since these were in stock at the location closest to me... The first one started to strip but made it all the way into the wood, the second one went in okay, the third again stripped without quite getting all the way in, and then the image is of the 4th one, which stripped so badly only half way in I had to back it out with vise grip. Returned and purchased GRK instead at a location an hour further away, haven't had a single failure on the GRKs.

            Hi Mark,
            Thank you for your review. I'm sorry that our HeadLOK screws did not performed as intended. This is very uncharacteristic of this fastener. Can you please answer some questions or call us so we can understand why this this happened? What type of drill (brand, voltage) did you use? What type of lumber are you driving the screws into? did you use the bit included in the box and did the fit feel loose or did it feel like it didn't fit. We can be reached at 800-518-3569 or techsupport@fastenmaster.com. Thank you. fastenmaster

              good quality but why this bit?
              is good quality I can refuse that but if you loose the bit there's no way to use unless you buy another box believe me I had this problem now I have almost all the box without use the regular bits box doesn't work with these screws.

                Love these screws! No bit slip and functioned as specified by manufacturer. It's a go to for me now. I used them on a bed frame I made. the look of the screw is clean, they self-countersink nicely. The price is excellent as well.

                Used these to fasten posts to a deck. The flat head sits flush so you can cover them with a composite fascia. Gives things a finished look, rather than having bolt heads sticking out. Very easy to drive in pressure treated lumber using a cordless impact driver. Drove over 30 8in and 100 4.5 using the same drive tip included with the boxes of products. Don't buy extra tips you won't need them.
