Lost some hardware for your IKEA KALLAX shelf? Don't worry, this replacement kit has you covered. It includes all the screws and dowels you need to assemble or repair a KALLAX 2x2 shelf unit (model number 602.758.12 in Black-Brown). Specifically, you get 8 screws (replacing IKEA part numbers 104321/104322) and 14 wooden dowels (replacing 101339). The shelf itself measures 30-3/8 inches by 30-3/8 inches. Super handy if you've moved and lost a bag of parts, or if you're rebuilding a shelf and some pieces got damaged. Important note: This kit is for KALLAX shelves only. If your shelf is older than June 2014, it might be an EXPEDIT model, and the hardware is different (KALLAX dowels are thinner and screws are shorter). So double-check your shelf before ordering! This kit saves you a trip to IKEA or searching online for individual parts. Everything comes together, so you can get your shelf sturdy and looking good again. Perfect for DIYers, renters, or anyone who needs to fix up their furniture without buying a whole new unit. Simple, affordable, and super practical.
