Wolf Tooth Pack Wrench Steel Hex Inserts

Wolf Tooth Pack Wrench Steel Hex Inserts are designed to expand the capability of the Pack Wrench system while maintaining the strength required for real-world bike service. Built for traveling mechanics, racers, and riders who want a compact yet capable tool kit, these inserts turn the ultralight Pack Wrench into a versatile, modular workshop essential. Each insert is CNC-machined from hardened steel and finished with electroless nickel plating for durability, corrosion resistance, and precise engagement. While the Pack Wrench body is optimized for minimal weight, these steel inserts are intentionally robust—providing the torque capacity needed for demanding tasks like cassette lockrings, crank systems, pedals, and frame hardware. The inserts interface via a 1-inch hex drive and are held securely in place by the Pack Wrench’s integrated magnets. Sold individually, they allow riders to build a customized tool setup tailored to specific bikes, drivetrains, and travel needs without carrying unnecessary bulk.
