Rated 5 out of 5 by great for connecting sleepers we used timberlocks for connecting sleepers. The screws are of high quality and screwed directly into the softwood sleeper without need of pilot holes. We used a Titan 40nm drill which had sufficient torque to screw all the way into the wood. Our other drill which is only 20nm torque could only get the screw in about 2/3rds. The timbrrlocks are a little expensive but as they made the job easier and are a high quality product I feel the extra expense is worth it. You can really feel them grip the wood as it goes In and we will use these again. 17 Mar 2015
Rated 5 out of 5 by Railway Sleeper Joiners I'd read lots of reviews about these screws & wanting to build raised beds from railway sleepers & needing to join them, so thought I had to give these a go, & I've got to say they were/are fantastic. I had solid oak softwood treated sleepers from Brazil that were extremely solid & heavy & I was very sceptical if these really would work, but work they did superbly. I did make a small guide hole with a drill, but used these 150 mm screws, to join 100mm sleepers onto other 100 mm sleepers & they screwed in using a drill (as instructed) very easily & has joined them together very strongly. I can't compare to anything else, but I can say with total honestly these are fantastic; well worth paying the money, a premium brilliant product. 19 Jun 2014
Rated 5 out of 5 by Timberlok sleeper screws "Does exactly what it says on the tin." A terrific fixing. 1 Aug 2014
Rated 5 out of 5 by Excellent product I was dreading joining oak sleepers together thinking that this product would not work. How wrong I was. After drilling a pilot hole the screws went through the oak with no problem at all, securing them very easily just as the instructions described. Will certainly use this product again 22 Jul 2014
