That's great! The Spring Bolt kits are time-saving, money-saving, and certainly save on headaches that may arise when joining handrails using conventional rail bolt kits. Thank you for your review! SureWood-LNL

I used this product to install 90 degree end returns on an oak wall railing. For this application I had to cut/shorten the springs and pin with a hacksaw, to reduce their length. For a straight connection this would not be neccesary. The product was not too difficult to install following the instructions. My issue or concern with this product is that it only holds the two pieces together with some spring pressure and therefore relies heavily apon glue or epoxy to make the joint solid. A rail bolt style fastener has MUCH greater clamping force than these spring bolts have. Make sure you use good strong glue.

Hi Harry, thanks for taking the time to leave a review. The main benefit of the Spring Bolt kit is its ease of assembly and use. You are correct that one needs a thin film of wood glue between the joints to form a permanent bond. Plus, the springs have a margin of error in them allowing you to slide the two pieces together to get a perfect alignment.

With the Spring Bolts, no special tools such as a rail bolt wrench are required. Plus, once all is said and done, the Spring Bolt joint is just as strong as one assembled with a standard rail bolt kit. We believe the Spring Bolt is the best rail joinery kit for the Do-It-Yourselfer that will produce a professional quality handrail joint every time. SureWood-LNL

    Total Junk!
    Followed the instructions to the letter, went to screw my rail to the volute and it wouldn't lock down. I tried this product (with a larger spring, rod and hole)on a newel post, as well....and my newel post wouldn't lock down, either. Do yourself a favor and find something else.

      I'm not sure if it was just my specific application that was the issue, but I could not get these to work at all. The springs wouldn't lock together, and ended up just getting bent. I went with a different railbolt product instead that worked great.

      Sorry to hear that this didn't work for you, JK. It could have been that two like-threaded springs made it into your kit by mistake, accounting for the lack of tension in the springs. This will be the first time we've heard of this, but I will pass along your comments to our manufacturing team for their review. If you have any questions or need more information, let us know, and we'll reply as quickly as we can. Thank you. SureWood-LNL
        "Spring Bolt" Works GREAT !!!
        I have had my railing parts for over 5 years only because I did not like the instructions on how to put it together. Thank goodness for Google !!! I found "Spring Bolt" and watched a few videos on YouTube. "Spring Bolt" works GREAT !!!

        Clever system
        I needed to create a continuous wood handrail for my customer. These springs were simple to install and structurally strong with epoxy

          Works like a dream!!!
          Couldn't believe how easy this was to use, I'm a skilled stair builder and have always used rail bolts in the past. Now that i found these i'm making the switch.

          Railing Hardware
          This product was easy to use and allowed me to make a strong good looking joint on my railings. It only required a drill bit and a square drive. Tools I already had. I work with my hands for a living buy I think anyone could use this hardware. I liked not having to use wood plugs to cover my hardware after I installed it.
