Key Features & Benefits
- Pass-through design — the hollow head lets threaded rod and studs up to 15mm pass straight through, eliminating the need for deep sockets or the tedious on-off-on cycle of conventional ratchets on long fasteners.
- Triple-drive output — 3/8-inch square, 1/2-inch square, and 1/4-inch hex in one tool covers virtually every socket and bit in a standard kit without adapters or second tools.
- 81Nm FUEL brushless torque — the highest torque in the M12 ratchet range, breaking free corroded nuts and running down structural bolts that lower-torque ratchets cannot handle.
- Included socket set (8–19mm + 21mm) — ships ready to work out of the box with pass-through sockets that fit the most common metric fastener sizes encountered in automotive and trade work.
- 21.45mm low-profile head — slim enough to access fasteners between components, pipes, and wiring where a standard socket wrench head would not fit.
- Dual LEDs — two work lights illuminate both sides of the socket simultaneously, eliminating shadows in deep cavities and engine bays.
The Ratchet That Handles Threaded Rod
The INSIDER solves the long-fastener problem that every mechanic and HVAC installer knows — running a nut down 200mm of threaded rod with a normal ratchet means constant removal and repositioning. The pass-through head lets the rod slide through the tool while the socket drives the nut, turning a five-minute job into a thirty-second one. The included socket set means no separate purchase needed.
