About This Product

FastenMaster TimberLOK is a hex head, heavy duty wood screw available in a variety of lengths and packaging sizes for applications such as attaching rafter or trusses to the top plate, headers, stair stringers and more. Designed to replace traditional 3/8 inch lag bolts, TimberLOK installs in a fraction of the time with fewer steps and less effort. Its sharp point and aggressive threads zip right into the densest woods. TimberLOK is tested and supported by engineering data that conforms to the most current ICC standards. It is also approved for use in ACQ or treated lumber. Includes 50, 6 inch wood screws with hex head, and 1 hex driver bit. In 1998, TimberLOK pioneered the category of structural wood-to-wood screws. Since then, TimberLOK and the rest of FastenMaster's LOK Line have been trusted by PROs everywhere.

        Q:If installed into a side of 2 x 4 stud (1.5 in width), would predrilled pilot hole be recommended? If yes, what diameter? If pre-drilled, what is minimal spacing between fasteners? What would be a shear strength with 2 in penetration into Douglass fir?
        by|Dec 25, 2023
        1 Answer
        Answer This Question

        A:  No predrilling is required. Per the advertising:"Replaces 3/8 inch lag bolts with no predrilling required" The question re: shear strength is more about the Doug Fir than the screw. It also depends on where in the 2x4 the screw is located (ctr vs edge)

            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.
