Working on your bike and missing a crucial axle nut or safety washer? This 60-piece assortment kit has you covered for most common repairs. It includes a mix of M8, M9.5, and M10 sized hex flange locknuts (some with serrated edges to prevent loosening), plus matching front (M8) and rear (M10) safety washers (those little clips that keep the axle in place). Made from carbon steel, so they're strong and rust-resistant. This is exactly the kind of kit you want in your toolbox for maintaining road bikes, mountain bikes, or cruisers. No more hunting for that one specific nut at the hardware store. Everything is neatly sorted (you get 5 full sets worth) for quick fixes on the trail or in your workshop. A must-have for any home bike mechanic.
