4‑Piece Heavy‑Duty Nut Splitter Set (12/14/18/21 mm)

• Sizes included: 12 mm, 14 mm, 18 mm, 21 mm heads for a wide nut range. Typical working ranges are about 9–12 mm, 12–16 mm, 16–22 mm, and 22–27 mm respectively, covering most M6–M18 nuts in automotive and machinery use.

• Construction: High‑strength steel bodies with heat‑treated chisel blade; designed to crack rusted, seized, or rounded nuts without damaging the bolt threads.

• Drive: Hex drive ends accept a wrench or socket for controlled force; longer bodies provide leverage for larger sizes.

• Case: Supplied in a molded storage case for organization and portability on site.

• Use cases: Ideal for corroded fasteners on cars, HVAC, farm equipment, and industrial maintenance where cutting wheels or torches are impractical.

How it works

• Place the ring over the nut, align the chisel with a flat, tighten the hex screw to split the nut; for stubborn nuts, rotate and repeat on the opposite flat for clean removal.

What’s included

• Nut splitters: #1 (12 mm), #2 (14 mm), #3 (18 mm), #4 (21 mm), plus blow‑mold case.
