Torque Wrench 20–220 Nm 1/2" Set with Cr-Mo Impact Sockets + Case ITW20220/S2 – Stix

Controlled tightening with a socket set

ITW 20220/S2 is a set built around a torque wrench with a range of 20–220 Nm and a 1/2" square drive. In addition to the wrench, the case contains 4 accessories: 3 × 1/2" impact sockets made of chrome-molybdenum steel Cr-Mo in sizes 17, 19 and 21 mm and a 1/2" extension bar with a length of 125 mm.

The set has been selected primarily for servicing wheels with alloy rims. The impact sockets are fitted with plastic protective sleeves, helping to safely tighten wheel bolts and nuts while reducing the risk of damage to the rim surface and fasteners.

Torque range 20–220 Nm

The ITW 20220/S2 torque wrench is designed for controlled tightening of bolts and nuts to a specified torque.

The wide range of 20–220 Nm allows it to be used for many service tasks requiring medium and high torque values.

The wrench is suitable for automotive workshops, tire service centers and garages – for tightening wheel bolts and nuts, as well as for work on suspension, braking systems, engine components and other fasteners requiring controlled tightening torque

Durable CrMo steel mechanism

Mechanism of the ratchet is made of durable chrome-molybdenum 42CrMo4 steel, which withstands the loads encountered during regular use.

The wrench body, in turn, is made of 40Cr chromium steel, providing suitable rigidity and durability for the entire construction.

The wrench has a length of 500 mm, providing suitable leverage when working with higher torque values. The longer handle makes it easier and smoother to reach the required torque, especially on fasteners tightened to values above 100 Nm.

4 accessories for 1/2" sockets

The set includes:

• 3 × 1/2" Cr-Mo impact sockets: 17 mm, 19 mm, 21 mm,
• 1 × 1/2" socket extension bar: length 125 mm.

The sockets are fitted with outer and inner plastic protective sleeves, making them particularly suitable for use on alloy rims. The 125 mm extension bar increases the tool's reach and makes it easier to access deeper fasteners

The 125 mm extension bar increases the tool's reach and makes it easier to access deeper fasteners.

Cr-Mo impact sockets for alloy rims

The set includes three 1/2" impact sockets made of chrome-molybdenum Cr-Mo steel in the most commonly used wheel sizes 17, 19 and 21 mm.

Each socket features an outer plastic protective sleeve, reducing the risk of accidental damage or scratching of the alloy rim surface, as well as an inner protective sleeve, protecting the surface of the wheel bolt or nut.

The color-coded sleeves allow quick identification of the socket size.

1/2" ratchet with 42 teeth

The wrench is equipped with a 1/2" square drive and a ratchet mechanism with 42 teeth. This drive size is well matched to the wrench’s operating range and allows the use of standard 1/2" sockets for fasteners requiring higher tightening torques.

The ratchet mechanism also makes work easier in areas with limited room for handle movement. The ball-lock release button makes sockets easier to attach and remove.

Clear torque adjustment

The ITW 20220/S2 has a mechanical scale that allows precise setting of the torque value. Adjustment is made by rotating the handle after first releasing the locking mechanism.

Once the required value has been set, the lock prevents the handle from accidentally changing the setting during use.

The wrench features a torque scale in the following units:

• Nm (N·m)
• kgf·m

Accuracy ±3%

The wrench mechanism allows the required torque to be set with an accuracy of ±3%. Once the preset value is reached, the mechanism signals it with a characteristic “click” and a noticeable release, indicating that tightening should be stopped.

Bidirectional operation

The ITW 20220/S2 allows controlled tightening to a specified torque in both clockwise and counterclockwise directions. This also allows it to be used on left-hand threaded connections, provided the required torque is within the wrench’s operating range.

The ratchet direction switch allows the direction of rotation to be changed quickly.

Individual factory calibration certificate

Each wrench has a unique serial number and is supplied with an individual document confirming testing and factory calibration. The document contains the accuracy test results and confirms that the wrench complies with the requirements of DIN EN ISO 6789-1:2017.

Case with complete equipment

The wrench and all accessories are stored in a practical case. It makes transport and storage of the entire set easier, with a dedicated place for each component, so the required socket or extension bar can be found quickly.
