2–24 Nm 1/4" torque wrench set with 17 accessories + case PTW224/S1 - Stix

Precise tightening with an accessory set

PTW 224/S1 is a professional set for controlled tightening of threaded connections at low torque values. The wrench offers a range of 2–24 Nm, a 1/4" square drive and an accuracy of ±4%, while the case additionally contains 17 accessories suited to many types of connections encountered during service work.

The low starting value of 2 Nm allows work on components requiring particularly careful tightening, while the maximum value of 24 Nm extends the wrench's application to many connections found in motorcycles, automotive equipment and precise assembly and service work.

The model belongs to the professional STIX PTW series, designed for regular workshop use.

Torque range 2–24 Nm

The PTW 224/S1 wrench allows precise setting of the required torque within the range of 2–24 Nm. It is particularly suitable for small bolts and connections where excessive tightening force could damage the thread, the component being fastened or the fastener itself.

It can be used, among other things, for work on engine accessories, covers, housings, clamps, motorcycle components and other parts for which the manufacturer specifies a torque within the tool's operating range.

Durable CrMo steel mechanism

The ratchet mechanism is made of durable 42CrMo4 chrome-molybdenum steel, well suited to the loads encountered during regular tool use.

The wrench body is made of black carbon steel, providing suitable rigidity for the entire construction. The wrench is 265 mm long and weighs 550 g, giving it a convenient size suitable for precise workshop work.

1/4" ratchet with 45 teeth

The wrench is equipped with a 1/4" square drive and a ratchet mechanism with 45 teeth. This design makes work easier in areas where handle movement is restricted.

Sockets are secured on the drive using a standard ball-retention mechanism.

Clear torque adjustment

The wrench has a mechanical main scale and a fine scale on the handle, allowing precise setting of the required torque value. Adjustment is made by rotating the handle after first releasing the lock.

Once the required value has been selected, the setting is secured using the locking knob located at the end of the handle. This design reduces the risk of accidental changes to the setting during use.

The wrench features a torque scale in the following units:

• Nm (N·m)
• kgf·m

Accuracy ±4%

The wrench mechanism operates with an accuracy of ±4%. Once the preset torque is reached, a characteristic “click” and a noticeable activation of the mechanism indicate that tightening should be stopped.

Bidirectional operation

The PTW 224/S1 allows controlled tightening to a specified torque in both clockwise and counterclockwise directions. This also allows the wrench to be used on left-hand threaded connections, provided the required value is within its operating range.

The switch on the head allows the ratchet direction to be changed quickly.

17 accessories included

The set includes:

• 4 × 1/4" sockets with Torx bits: T20, T25, T30, T40,
• 6 × 1/4" sockets with HEX bits: H3, H4, H5, H6, H8, H10,
• 1 × 1/4" socket with long HEX bit: H5 × 100 mm,
• 2 × 1/4" sockets with Phillips bits: PH1, PH2,
• 2 × 1/4" sockets with slotted bits: SL4, SL7,
• 1 × adapter: 1/4"F × 3/8"M,
• 1 × 1/4" socket extension bar: length 100 mm.

The accessories are made of chrome-vanadium Cr-V steel. The varied selection of bits allows many types of connections to be serviced without the need to assemble a separate set of basic sockets and bits.

100 mm extension bar and adapter

The 100 mm long extension bar for 1/4" sockets makes it easier to access deeper-set and hard-to-reach bolts.

The adapter 1/4"F × 3/8"M allows the wrench to be used with suitable 3/8" sockets, provided the wrench's specified torque range is observed.

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 17 accessories are stored in a fitted case that makes the set easier to transport and store while keeping the individual components organized.
