RUKO SCE-DIN22568-HSS-60°-5/8 estrattore viti

When a bolt snaps off in a threaded hole, this RUKO screw extractor removes the broken piece without damaging the surrounding threads. It is used in workshops, maintenance departments, and on construction sites where fasteners seize or break.

Why choose it

The left-hand spiral bites into the broken fastener as you turn counterclockwise, providing a secure grip for extraction. HSS construction offers high hardness and wear resistance for repeated use.

Ideal use cases

• Removing broken bolts from engine blocks, machinery, or pipe flanges
• Extracting snapped screws in metal, plastic, or wood
• Repair work where re-tapping threads is not an option

Good to know

Use with a tap wrench, adjustable wrench, or drill with an appropriate adapter. Drill a pilot hole in the broken fastener according to the core diameter before using the extractor.
