Inline skaters, if you're tired of stripped or worn-out axle screws, this 10-piece replacement set has you covered! These 31mm screws are perfect for front wheel replacement on most inline skates, made from durable iron with a protective coating on the connecting part so they won't loosen during intense skating sessions. Each screw has a 6mm outer diameter and requires a 4mm hex key for installation - and here's the pro tip: you'll need two hex keys, one for fixation and another for doing the actual work. The female and male screw design works with skating shoes that require this specific fitting type on the wheels. The quality is noticeably better than cheap OEM screws that strip easily or rust over time. Whether you're an aggressive skater putting your equipment through hell or just someone who needs to replace worn hardware, these screws will keep your wheels securely in place. No more worrying about wheels coming loose mid-skate or struggling with damaged screw heads that won't budge. Keeping a set of these in your gear bag means you'll always be ready for quick repairs at the skate park or on the go. Your skating sessions will be safer and more enjoyable when you're not constantly worrying about your hardware failing. For the price, having 10 replacement screws on hand is absolute peace of mind for any serious skater!
