Orion Motor Tech Metric Thread Chaser Set 15‑pc M6–M12 — Coated Steel Taps & Dies with Carry Case

Orion Motor Tech's 15-piece metric thread chaser set is a compact rethreading kit designed to clean, repair, and restore damaged metric bolt and nut threads from M6 to M12 without replacing parts.

When a bolt or tapped hole has dirty, corroded, or slightly damaged threads, the OMT Metric Thread Chaser Set offers a faster, lower-cost alternative to replacing components. The kit assembles seven taps, seven dies, and a dedicated thread file in a molded carrying case so you can address common thread issues on cars, machinery, household items, and DIY projects. Built with coated steel and shaped for use with standard wrenches, the set is made to fit into a mechanic's toolbox or a home workshop and to be straightforward for both pros and hobbyists.

How will this set restore damaged threads?

The taps and dies are manufactured to re-form and clean existing metric threads rather than cut new ones, which reduces risk of removing too much material. Each tool engages worn or contaminated threads to straighten and reprofile them, improving fitment for fasteners.

• Includes seven common metric taps and seven matching dies for precise re-threading.
• Thread file removes burrs and cleans multiple thread pitches by hand.
• Black oxide or zinc coating helps resist corrosion during repeated use.
• Hexagonal form allows operation with a socket wrench for controlled torque.

What sizes and thread pitches are in the kit?

The set covers frequently used metric sizes across M6, M8, M10, and M12, with multiple pitches so you can pick the correct tool for the fastener at hand. This range makes the kit suitable for European and Asian hardware standards commonly found in automotive and industrial applications.

• M6 x 1.0 for small machine screws and fittings.
• M8 x 1.25 for medium bolts and assemblies.
• M10 x 1.25 and M10 x 1.5 for differing standard pitches.
• M12 x 1.25, M12 x 1.5, and M12 x 1.75 for larger mounts and brackets.

How durable and easy to use are the tools?

Each piece is forged from high-grade steel and finished with a corrosion-resistant coating to extend service life. The hexagonal taps and dies accept common socket or wrench sizes so you can apply steady, controlled force without specialized holders.

• Durable steel construction resists deformation during rethreading.
• Coatings help prevent rust and keep threads cleaner between uses.
• Blow-molded case organizes components and protects cutting edges.
• Works with standard wrenches—no proprietary tools required.

Can this kit save time and cost versus replacing parts?

Yes — by restoring threads rather than replacing tapped components or bolts, the kit reduces downtime and material cost. It’s especially useful for thread damage caused by corrosion, cross-threading, or debris, letting you reuse expensive fittings and repair mounting holes on-site.

• Avoids ordering and waiting for replacement parts in many cases.
• Makes quick repairs on vehicles, machinery, and household fixtures.
• Portable case keeps everything accessible for roadside or shop work.
• Thread file adds a non-invasive option for delicate thread cleanup.

Who this is for: The Orion Motor Tech 15-piece metric thread chaser set is aimed at mechanics, maintenance technicians, fabricators, and DIYers who encounter worn or fouled metric threads and prefer repairing to replacing. If you work on cars, motorcycles, industrial equipment, plumbing fittings, or regularly refurbish assemblies, this kit gives a practical, durable solution to restore thread fitment and prolong component life.
