Sealey STW306 Digital Angle Torque Wrench, 1/2" Sq Drive, 20NM-200NM

Sealey STW306 Digital Angle Torque Wrench

The Sealey STW306 Digital Angle Torque Wrench is a precision instrument engineered for professionals who demand accuracy, reliability, and versatility in torque application. Designed with a 1/2" square drive, this wrench delivers a torque range of 20 Nm to 200 Nm (equivalent to 14.7–147.5 lb‑ft), making it suitable for a wide array of automotive, aerospace, and industrial tasks.

Key Features

• Digital Torque Display: A clear, high‑contrast LCD screen shows real‑time torque values in both Nm and lb‑ft. The display updates instantly, allowing the user to stop the wrench at the exact torque setting.
• Angle Functionality: The integrated angle sensor measures the rotation of the fastener, providing an additional layer of control for applications where angular positioning is critical.
• Wide Torque Range: From light assembly work at 20 Nm to heavy-duty fastening at 200 Nm, the STW306 covers most torque requirements encountered in professional settings.
• Robust Construction: The wrench features a hardened steel head and a durable housing that resists wear, ensuring long‑term performance even under demanding conditions.
• Ergonomic Design: A comfortable, non‑slip grip and a balanced weight distribution reduce operator fatigue during extended use.
• Battery‑Operated: Powered by a rechargeable battery, the wrench offers cordless convenience while maintaining consistent torque output.
• Safety Features: An overload protection mechanism prevents damage to fasteners and the tool itself by cutting off power if torque exceeds the set limit.

Technical Specifications

Applications

The STW306 is ideal for:

• Automotive assembly and maintenance, including engine block fastening and suspension component installation.
• Aerospace manufacturing where precise torque and angle control are mandatory for safety compliance.
• Industrial machinery assembly, such as conveyor systems and heavy equipment.
• Custom fabrication projects that require consistent torque application across multiple fasteners.

Operating Instructions

1. Select Torque: Turn the dial to set the desired torque value. The LCD will display the chosen setting.
2. Attach Fastener: Place the wrench on the fastener and ensure a secure fit.
3. Apply Torque: Turn the wrench clockwise. The digital readout will increase until it reaches the set torque.
4. Release: Once the target torque is achieved, the wrench will automatically stop. Release the handle to disengage.
5. Angle Verification: Observe the angle sensor reading to confirm the fastener has been rotated to the required position.
6. Reset: Turn the dial back to zero before the next use.

Maintenance and Care

• Cleaning: Wipe the wrench with a dry cloth after each use. Avoid abrasive cleaners that could damage the LCD.
• Battery Care: Recharge fully before first use and store the battery in a cool, dry place when not in operation.
• Inspection: Periodically check the drive socket for wear or damage. Replace if necessary to maintain torque accuracy.
• Calibration: For critical applications, perform a calibration check against a known standard torque value every 12 months.
