This XZN 12 pattern impact socket bit is engineered for mid-range spline fasteners frequently encountered in automotive and mechanical applications. The 12-point spline configuration provides robust engagement with the fastener, distributing torque evenly across multiple contact points for reliable performance. Featuring a 45mm bit length for extended reach capability, this socket bit excels in accessing recessed fasteners where standard tools cannot reach. The impact-rated construction withstands the demands of power tool use, whilst the 1/2" square drive ensures universal compatibility with professional impact wrenches. This size is particularly popular in brake system work and drivetrain applications where XZN fasteners are specified, offering the combination of reach and strength required for professional servicing.
