Chemical threadlockers are a great boon. They keep nuts from coming loose at inopportune moments, like braking into a turn at 200 km/h or losing the hitch ball on the trailer at 4 am on a deserted country road. Traditionally they’ve taken the form of a liquid or gel, which is applied to the threads as the parts are assembled. Loctite’s QuickTape 249 is a threadlocker that comes in tape form. And it’s applied just like Teflon pipe tape – two wraps are plenty. Now you can assemble the part or wait as long as a month. QuickTape 249 makes working in tight places or overhead simpler, because the chemical stays put. And it’s just as effective as the old-fashioned liquids.
