Sundpey 3-Piece Torque Wrench Set – 72-Tooth, Dual-Scale, ±3% Accuracy (1/4, 3/8, 1/2 Drives)

Introducing the Sundpey 3-Piece Torque Wrench Set, a versatile toolkit designed for precise fastening across bicycling, automotive, and light industrial tasks. This trio features dual-range capabilities and factory calibration with ±3% accuracy, each accompanied by its own calibration certificate. The three drives cover a wide tightening spectrum: 1/2" drive from 10 to 170 ft-lb, 3/8" drive from 5 to 45 ft-lb, and 1/4" drive from 20 to 220 in-lb. A sturdy plastic case keeps everything organized, protected, and easy to transport for work at the shop, in the garage, or on the road.

Precise design and durable construction

• Premium materials include chrome vanadium steel and aluminum alloy, delivering strength and corrosion resistance for long-term use.
• Ergonomic handle with anti-slip striping provides secure control, even during extended sessions, while non-reflective scale markings stay readable in varied lighting.
• The 3/8" drive features a 72-tooth reversible ratchet head for smooth operation in both directions, enabling efficient work in tight spaces.
• Dual-alert torque operation combines an audible click with subtle handle vibration when the preset value is reached, helping to prevent over-tightening or under-tightening.
• A simple secure locking system lets you set and lock torque values quickly—pull down, rotate to the desired setting, and release to lock automatically.
• The quick-release button enables fast socket changes while maintaining secure retention, supporting quick transitions between tasks.

What you can accomplish

• Three drive sizes in one kit reduce the need to swap tools, saving time on bicycle maintenance, automotive repairs, and industrial projects.
• Applications range from wheel screws and engine components to machinery bolts and electrical installations, benefiting professionals and DIY enthusiasts alike.
• Calibration certificates accompany each wrench, offering traceable documentation of performance and peace of mind for repeatable results.

Usage tips and support

Lock the setting, apply torque with a straight stance, and listen for the precise click and feel the vibration as the target is reached. Periodically review calibration certificates to confirm ongoing accuracy. Sundpey supports your projects with responsive service and guidance for any component you use.
