The Jonnesway 1/2" Spline Bit Socket (M9 x 100 mm) is a high-performance specialized tool designed for working with XZN (spline) profile fasteners commonly found in European vehicles and heavy machinery. Its extended length of 100 mm allows access to bolts located in deep or recessed areas, such as engine cylinder heads and brake systems, where shorter sockets cannot reach.
Manufactured with a chrome vanadium base and a maximum hardness S2 steel bit, this professional M9 bit socket withstands high torque levels without deforming or damaging the screw head. Its 1/2" drive makes it compatible with standard ratchets and breaker bars, making it a key tool for mechanics performing complex repairs on engines from brands such as Volkswagen, Audi, or Mercedes-Benz.
