Electric Wrenches

About this product These digital torque wrenches operate with a deviation of only ±2 percent clockwise and each comes with a calibration certificate. This ensures reproducible tightening values on vehicles, equipment, and machinery, preventing damage to threads or components. A clear trigger and the digital LED or LCD display help you precisely hit the target value without guesswork. The display is easy to read and supports five selectable units: Nm, kgf.cm, lbf-ft, lbf-in, and kgf.m. You can directly import values from manuals and customize the display to your preferences. Even in low light, the target value, current torque, and status messages remain clearly legible, reducing operating errors and increasing working speed. The alloy steel body undergoes a six-stage heat treatment and is chrome-plated. This results in high strength, corrosion protection, and a smooth, easy-to-clean surface. The 72-tooth ratchet allows for small return angles for precise work in tight spaces, and the mechanism is designed for consistently smooth release. The reversible ratchet head operates in both clockwise and counterclockwise directions. Sockets can be changed quickly with one hand, significantly speeding up tire service, suspension work, and assembly. Presets are intuitive and remain stable, allowing you to focus on tightening bolts cleanly. A shockproof case protects the wrench during transport between the garage, workshop, and storage. Adapters and extensions are clearly arranged for easy access. Instructions and a calibration certificate are included and readily available for settings and documentation. Key Differences The SX11100 is a single 3/8" digital wrench with a wide display range of 6.7–135 Nm or 4.94–99.57 lbf-ft and also includes a 3/8" to 1/2" adapter and a 3/8" extension. The SX3812 is a two-piece set with two separate digital wrenches in 1/2" and 3/8" drives, allowing you to switch between large and medium-sized fasteners without an adapter. The SX11100 is more compact and lighter, making it easier to use in tight spaces, while the SX3812, with its two lengths and drive sizes, covers a wider range of workshop applications. Both models feature ±2 percent clockwise rotation, a 72-tooth ratchet, an LCD display with five units, and come with batteries, instructions, and a calibration certificate.
