Product Details
✓WIDE METRIC COVERAGE — This set includes two tools sized for nuts from 5 to 20 mm and 14 to 27 mm, giving you the range to handle most common fastener sizes you will encounter during automotive, industrial, or general maintenance work. The overlapping capacity between the two pieces means you always have the right fit on hand without needing to source additional tools for mid-range nuts.
✓PROTECTS BOLT THREADS — Unlike cutting wheels or chisels, a nut cracker tool applies controlled pressure through a threaded splitting pin that cracks the nut cleanly along one side. This approach preserves the bolt threads beneath, so you can reuse the stud or bolt without chasing damaged threads or replacing hardware, saving time and money on every stubborn fastener you encounter.
✓SIMPLE MANUAL OPERATION — No batteries, no air lines, no hydraulics. Position the ring over the stuck nut and tighten the thread to engage the blade. Controlled mechanical pressure does the rest, splitting even heavily corroded or seized nuts. This makes the tool ideal for field service, roadside repairs, and confined engine bays where powered tools cannot reach or are impractical to use.
✓EASY TO CARRY — At only 533 g total for both pieces, this kit is light enough to keep in a mobile toolbox, a service truck, or a workshop drawer without adding unnecessary bulk. The compact two-piece format delivers coverage comparable to larger kits while occupying far less drawer or pouch space, which matters when every inch of storage counts on the job.
✓DESIGNED FOR REAL-WORLD REMOVAL JOBS — Rusty exhaust manifold studs, seized suspension bolts, corroded plumbing fittings — whenever a conventional wrench just rounds the flats, these splitters let you crack the nut and move on. Each piece features a ring that seats around the nut and a threaded pin that drives a blade into the flat, removing broken nuts quickly so the repair can continue.
