These plastic inserts are for repairing stripped or damaged screw holes caused by installation errors, detachment, water leaks, or severe falls. I have other items for sale as well, so please take a look at #polvere's listings if you're interested. You can repair the damage by re-drilling an 8mm diameter, 9mm deep hole, hammering the insert in with a rubber mallet, applying glue, and then screwing in the hardware. Additional inserts are available for 100 yen each. Please inquire before purchasing. I am also selling on other platforms, so I may remove this listing if an item sells elsewhere. #ski #bindings #hardware #screws #bolts #Pozidriv #PZ3 #lifter #longscrews #screw holes #repair #insert #anchor
