    Please Note

    Only one (1) LayerShift screwbutton wrench is needed for tightening.  You do not need to purchase a wrench for each button.

    With a simple twist or few, the LayerShift Screw Button Wrench provides a solution for sore fingers that desperately try to secure a screwbutton nut firmly in the tightest of spaces.

    Solving with a Twist

    A screwbutton's main characteristic is its plastic nut, which when twisted clockwise, rises upward towards the button rim. Optimally, you will twist the nut as far as it can go until it cannot twist any more.  This ensures a tight, wiggle free contact between the button and the wood or metal panel it is install onto.

    Often this is done manually, using your fingers to rotate the nut until it secures to the wood or metal control panel.  However, some button layouts do not make this physically possible, as the gaps between buttons do not accomodate one's fingers after a certain height. Players are left with buttons slightly loose, or give up installing them.

    LayerShift's wrench aims to close that gap with a 3D printed wrench.  At the top is a large hexagonal shape that accomodate your fingers.  The bottom mimics each popular brand's screwbutton nut shape, while having a minimal thickness to fit in most gaps. Twisting slightly to line up the bottom with the screw but, then pressing down grips the nut.  You can now twist the nut into place.  

    Color Coded

    Each model of LayerShift screwbutton wrench has a distinct color to represent both the brand it's designed for and the size of button:

    1. Works well. Clearly a 3D printed tool.

      I have no issues with the product and it works as expected. The price is very reasonable for a specialized tool.

      Disappointed that on closer inspection, it appears to be a run of the mill resin product made on a hobby 3D printer. Visible print lines, non-uniform texture.

      It performs the job better than tightening or loosening by hand. The product just looks unprofessional and something I could make at home.

      I clearly didn’t. It’s why we buy Starbucks instead of making coffee at home. I guess I just feel like I could have made coffee at home.

    2. Good for those first couple Sanwa screw buttons, but....

      The more buttons you put in, the less room you actually have to wrap the wrench around the buttons. You won't be able to screw in all eight buttons using the wrench. At least that was the case for my Mad Catz TE.

      This is not a fault of the wrench, but really the Sanwa screw buttons themselves. Perhaps a wrench that only grabbed portions of the button would do better (think pliers). There's still room between the buttons, but just not enough for the whole wrench to go in.

    3. Does its job

      I bought this because I bought Sanwa buttons from another site and one of the screws was on too tight when I got it. The wrench is easy to use and perfect for loosening and tightening screw buttons. on Apr 30th 2021
