WHY CHOOSE OUR MULTI SPLINE EXTRACTORS
Conventional tapered spiral extractors expand broken bolts, wedging them tighter into their tapped holes. These multi spline extractors bite directly along the internal walls of the bolt without spreading the outer shell, releasing frozen and rounded hardware with minimal effort.
PERFECT FOR
Automotive Engine Bays: Pull sheared exhaust manifold studs, rounded thermostat bolts, and broken bracket screws.
Machinery and Plant Equipment: Back out stripped machine screws and frozen studs from threaded cast iron castings.
Plumbing and Pipe Fittings: Remove rounded hex plugs and broken pipe nipples from brass and steel manifolds.
