LD-184 Broken Bolt Screw Extractor 5pc Set | Wholesale Supplier

The LD-184 Broken Bolt Screw Extractor 5-piece set is an indispensable rescue tool for mechanics, maintenance technicians, and fabricators who regularly encounter damaged or broken fasteners. Each extractor features aggressive left-hand spiral flutes that bite into the damaged fastener head or shank as counter-clockwise torque is applied. This reverse-thread design causes the extractor to grip tighter as turning force increases, progressively embedding the flute edges into the fastener material until sufficient torque transmits to back the fastener out of the threaded hole. The chrome vanadium steel construction is hardened and tempered to HRC 58-62, providing the strength needed to withstand high extraction torque without twisting or breaking. The five graduated sizes cover the range from small M3-M4 machine screws up to heavy M11-M14 bolts commonly found in automotive engines, industrial machinery, and structural assemblies. The extractors can be used with either a T-handle tap wrench for manual extraction or with a reversible drill set to counter-clockwise rotation for powered extraction. The set is packaged on a blister card with a clear size chart showing bolt diameter ranges for each extractor number. Whether removing a broken exhaust manifold bolt from an engine block, extracting a stripped Allen head screw from machinery, rescuing a rusted chassis bolt during restoration, or salvaging a broken tap from a precision threaded hole, the LD-184 extractor set provides the grip and strength needed when conventional tools have failed.
