ACDelco ARM601-34 3/8 and 1/2 Inch Heavy Duty Digital Torque Wrench Kit – ISO 6789 Calibration Certificate

Overview

The ACDelco ARM601-34 Digital Torque Wrench Kit brings together two precision tools in a compact, value-focused package. Built to meet ISO 6789 standards, this combo includes a certificate of calibration and two rugged hard-shell cases to keep each wrench protected between jobs. Real-time torque values, a responsive buzzer, and a bright LED notification help operators stay in tune with exact specifications while maintaining workflow momentum.

• Two calibrated digital wrenches: 3/8" (ARM601-3) and 1/2" (ARM601-4)
• Real-time torque readouts in ft-lbs and Nm
• Buzzer alert and LED flash for torque confirmation
• Lightweight, ergonomic design with durable alloy construction
• Includes two protective hard-shell cases and a calibration certificate

Dual precision wrenches for every task

The ARM601-3 spans 3.7 to 37 ft-lbs, while the ARM601-4 covers 14.8 to 147.5 ft-lbs. Each tool displays torque on a clear LCD screen, with the option to switch between ft-lbs and Newton-meters. The combination is designed to handle tight spaces and varied fastener sizes with consistent readings that technicians can trust during critical assemblies.

Audible and visual confirmation

A built-in buzzer and a vivid LED indicator offer immediate feedback when the target torque is reached. This makes it easier to sequence tasks in busy shops or noisy environments without second-guessing the result, while the LCD remains legible in different lighting conditions.

Quality you can rely on

Constructed with a durable alloy body and a lightweight, ergonomic soft-grip handle, the ARM601-34 tools balance comfortably in hand and reduce fatigue during longer sessions. The two included hard-shell cases keep the wrenches organized, protected, and ready for transport between job sites.

Practical use cases

Ideal for automotive maintenance, motorcycle service, and industrial applications where precise torque matters. The kit integrates smoothly into daily workflows, supporting procedure consistency from on-lift repairs to field diagnostics, all without overpromising results.
