Rated 5 out of 5 by Excellent for fixing sleepers Great product - just the right thing when used to fix sleepers for raised flower beds. Supplied with drill attachment making it easy to use. 2 May 2016
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
