Engineered with an exclusive X-CORE pinless four-lug ball-and-socket design, this set provides 4X more durability than traditional pinned products. The 30° off-center operating angle and smooth 360° rotation allow for superior access and speed when removing stubborn fasteners in cramped spaces. Built from chrome molybdenum alloy steel with a black oxide coating, these extensions ensure exceptional strength and long-lasting corrosion resistance.
