Torque Wrenches

JCB torque wrenches are calibrated precision instruments for fastening where getting the torque right matters. Under-tighten a wheel nut and it loosens under load. Over-tighten a cylinder head bolt and the thread strips or the gasket fails. The JCB range covers 3/8-inch drive from 5-25Nm for small engine work, 1/2-inch drive models in 10-60Nm, 20-120Nm and 60-330Nm ranges for automotive and construction fastening, and a 3/4-inch drive 200-800Nm model for agricultural and heavy machinery. All feature ratchet heads for fast repositioning, audible-and-feel click mechanisms for positive torque indication, and are supplied with calibration certification. Stored and reset correctly, a quality torque wrench is a tool for life.

Buying Guide

Match the torque wrench drive size and range to your application. A 1/2-inch drive in the 20-120Nm range covers the majority of automotive work — wheel nuts, caliper bolts, driveshaft nuts and most engine fasteners. For small engine and accessory work, a 3/8-inch drive in the 5-25Nm range provides the precision needed for light fasteners. For agricultural machinery, large plant equipment and commercial vehicles, step up to a 3/4-inch drive high-torque model. Store the wrench at its lowest setting after use to preserve the spring mechanism. Never use a torque wrench for loosening fasteners — use a standard breaker bar or ratchet for that task.

Frequently Asked Questions

How do I use a torque wrench correctly?

Set the torque to the manufacturer's specification for the fastener. Tighten at a steady, controlled pace until you hear and feel the click — stop immediately. Do not continue tightening after the click. Reset to minimum torque setting after use and store in the case provided.

Do JCB torque wrenches come calibrated?

Yes. JCB torque wrenches are supplied pre-calibrated and with calibration documentation. For professional workshop use, torque wrenches should be recalibrated periodically — typically every 12 months or after any significant overload event.

What torque setting do wheel nuts need?

Wheel nut torque varies by vehicle and stud size — always check the manufacturer's specification. Typical passenger car wheel nut torque is 100-130Nm. Always use the vehicle manufacturer's specified value, not a generic estimate.
