smint 4 Posted June 7, 2020 Hi All, just started building my XV-01 long damper and I'm running into a couple of problems. I'm finding some screw are super tight to screw in, its as if the screw is either too long or the hole isn't deep enough. I've double checked the screws and i'm using the correct ones I'm also using JIS screwdriver. There's just no way these screws are going in all the way. I'm tempted to get a drill to shave out the hole a little. The screws im having problems with are the rear gear housing. Anyone have any ideas? Share this post Link to post Share on other sites
Finnsllc 917 Posted June 7, 2020 sometimes u need to tap the hole before the screw will bottom out in the correct position https://www.tamiyausa.com/shop/option-parts/rc-m3x05mm-thread-forming-tap/ 2 Share this post Link to post Share on other sites
mtbkym01 4008 Posted June 7, 2020 You could try a little bit of grease on the screw threads, I often do this when first cutting a new thread on a new build 2 Share this post Link to post Share on other sites

Running the screw in until it won't go further, then backing it out, going in again (rinse/repeat) works also. Flogs your wrists though, but an electric screwdriver can help once you have the screw started by hand. Not my favourite technique, as you don't have the control and feel as a quality hand powered driver. 1 Share this post Link to post Share on other sites
Gazzalene 171 Posted June 7, 2020 I tend to run a M3 allen head bolt through first. The allen head is way more robust than the JIS/POZI/PHILIPS. Then when you use the kit bolt/screw you will not damage the head. 2 Share this post Link to post Share on other sites
smint 4 Posted June 8, 2020 Thanks for the tips everyone. I got it in. Repeated rotations in the hole and used some grease on the tip. 3 Share this post Link to post Share on other sites
Otis311 196 Posted June 23, 2020 Tamiya makes a tool for this (thread forming tool) but as other have stated you can just use an extra screw and obtain the same results. I have made it a habit to use a tiny bit of grease on the machine screws going into plastic, especially the reinforced plastics. 1 Share this post Link to post Share on other sites
