Key features

• •Precision-Engineered Axle System: inline skate wheels screws features stepped spacers (11.8mm OD, 6.5mm ID) that perfectly align bearings within wheels. the dual-length axles (32.3mm & 38.5mm) accommodate different wheel widths while reducing bearing drag for smoother rolling performance.
• •High-Performance Aluminum Construction: od roller skate bearings screws crafted from lightweight yet durable aluminum alloy that dissipates heat during intense skating. the material resists deformation under pressure while maintaining precise bearing alignment for consistent performance.
• •Complete 20-Piece Maintenance Kit: skate wheel socket screw includes both short and long axles with matching spacers, plus two 4mm wrenches for on-the-go adjustments. the comprehensive set provides multiple replacements for all wheel configurations in one portable case.
• •Tool-Included Quick Installation: skate wheel axles socket screws designed for tool-free bearing swaps with the included dual wrenches. the recessed spacer design automatically centers bearings during installation, eliminating guesswork and ensuring proper wheel alignment every time.
• •Optimized Bearing Protection: inline roller skate screws shaft hex reduces side-load stress on bearings with its precision-machined spacers. the system prevents bearing collapse during hard landings while allowing free rotation to maintain speed and reduce wear during skating sessions.
