The Wrench is an IC2 tool that rotates IC2 machines on right-click and dismantles them with a 20% intact chance on sneak right-click.
Guide
Alloy 3 Copper Ingots with 1 Tin Ingot per Bronze Ingot, or smelt Bronze Dust from an IC2 macerator mix; you need three Bronze Ingots total.
On a vanilla crafting table, place Bronze Ingots in the canonical IC2 T-shape (two top corners, one center, one bottom-center) to produce one Wrench.
Hold the Wrench and right-click a Generator, Macerator, or Electric Furnace; the front face snaps to the side you are looking at.
Sneak and right-click the same machine; there is a 20% chance the machine drops intact and an 80% chance only the Machine Block and internal parts drop.
When the Wrench durability bar turns red, combine it on a vanilla anvil with Refined Iron or Bronze depending on your IC2 build to restore charges.
Switch to the Electric Wrench in lossless mode for a guaranteed 100% intact dismantle; the standard Wrench keeps its 20% chance even after repair.
Place three Bronze Ingots on a crafting table in the IC2 wrench T-shape: two ingots in the top corners, one in the center, and one in the bottom-center slot.
A regular IC2 Wrench has a 20% chance to drop the machine intact when you sneak right-click it, and an 80% chance to drop only a Machine Block plus internal components.
No. The Wrench only rotates and dismantles IC2 machines such as Generators, Macerators, and Electric Furnaces; it does not affect vanilla pistons, hoppers, or blocks from other tech mods.
Combine the damaged Wrench on a vanilla anvil with Refined Iron or Bronze, depending on your IC2 version, to restore its durability bar.
The Electric Wrench consumes EU and can be set to lossless mode for a guaranteed 100% intact dismantle, while the standard Wrench always keeps the 20% chance.
