Hammering, grinding, and cutting to remove the screw may render the hole unusable.

Plastic is a fairly soft material, and a light touch is a must if you want to reuse a hole in plastic after removing a screw.

A stripped screw in wood will likely be flush with the material or slightly lower than the surface, so using a stripped screw extractor is your best bet to retrieve the screw.Be extra diligent when using power tools and cutting materials. Stripped screws in metal need to be removed carefully, otherwise you risk scratches or damage.Removing a stripped screw from each material, however, presents its own challenges. Most of the methods described below will work if a stripped screw is embedded in metal, wood, or plastic. Removing Stripped Screws From Metal, Wood, and Plastic: Why the Material Matters Ahead, learn how to remove a stripped screw the best way, as well as alternatives you can try using materials you likely already have on hand. We tested several methods for removing stripped screws and found a clear winner. Though stuck fasteners with stripped heads can certainly slow down your progress, they’re not impossible to deal with. I didn't put as much force on it when tightening it - I'd say maybe 1/2 to 3/4 of the force it took to loosen it.The best-laid DIY project plans can hit a snag if a stripped screw turns up. I have a nice 3-point spanner wrench, and it took a good amount of strength to open it. Maybe I'll even open it up again and move it to the next tick mark to see what happens.Īnother thing I am not sure of is how tight the case back should be tightened. Maybe I'll set it once or twice a month if it bugs me. Now, a week after regulating it one tick mark, it is consistently 10 seconds slow per day. I would check it almost every day, and it was always 12 seconds slow. Yes, it went from +2 seconds per day to -12 seconds per day in the first month or so, but then it stayed right at -12 seconds for another month. The thing I do like is that it's extremely consistent. I moved it one tick mark in the + direction - half the total adjustment. Yes, when I opened it, the line was pointing perfectly at the middle line between the +/- marks. Should anything more than this fine adjustment be done by a professional? I've heard that the Fine Regulation screw works like a cam, so is it possible that going to the next tick mark (the full range of adjustment) would make more than another 2 second difference? Now it's losing 10 seconds/day instead of 12. Then re-siliconed the gasket and tightened the case back.Īfter one week, the adjustment only changed it by 2 seconds per day. I moved the screw one tick toward the plus - half the total possible adjustment.

If you look at the picture, you can see there are two ticks of adjustment for both + and 1. I'm not unhappy with that by any means, but I decided to try and regulate it myself anyway, since it didn't look that difficult. After a couple months, it stayed here consistently at -12 seconds/day. A couple weeks later, it started losing time and finally settled in at losing 12 seconds per day. This is my first automatic and I absolutely love the watch.Īs far as accuracy, the first week I owned the watch it was almost perfect - it gained less than 2 seconds a day over that week. I have an Invicta 9937 with the SW200 movement.
