Atlas Copco TWIST SR Pneumatic Straight Torque Screwdrivers

Atlas Copco TWIST SR Pneumatic Straight Torque Screwdrivers

The Atlas Copco TWIST SR family is built for pneumatic straight screwdriving in assembly processes where torque consistency and repeatable tightening matter.

The range offers different start and reverse configurations, making it easier to match the screwdriver to the station, production pace, and joint type.

Key Features

• Repeatable tightening: The slip-clutch mechanism suits joints that need torque accuracy even when joint stiffness varies.
• Straight-body handling: The straight form factor fits industrial assembly stations and long production shifts.
• Two operating styles: The range includes lever start with reverse ring models and push start with reverse button models.
• Wide torque coverage: The family covers different torque ranges, from 0.5-4.2 Nm up to 2.2-6.5 Nm and 1.5-10.0 Nm.
• Compact weight and length: The models stay relatively compact, with weights from 0.65 to 0.9 kg and lengths from 211 to 246 mm.
• Standard air connection: Depending on the model, the air inlet is 1/8 or 1/4, with recommended hose sizes of 6 or 8 mm.

Frequently Asked Questions

How do I choose the right TWIST SR model?
Step 1: Define the required torque range for the joint.
Step 2: Match the free speed to your station pace.
Step 3: Choose the operating style that fits your workflow, lever start or push start.
Step 4: Confirm the air inlet thread and recommended hose size.

What is the difference between lever start and push start models?
Lever start models are activated by a lever and use a reverse ring.
Push start models are activated by push action and use a reverse button.

Which applications are these screwdrivers best suited for?
They are well suited to assembly stations that need accurate, repeatable tightening, including joints where stiffness can vary.

How should I choose between higher and lower speed models?
Higher speed models are generally better when cycle time is important.
Lower speed models can be better when you want more control over the tightening process.

What air connection should I prepare?
Some models use a 1/8 air inlet and others use 1/4. The recommended hose size is 6 mm or 8 mm depending on the model.

What should be checked during routine maintenance?
Keep the air supply correct, match the hose and fittings to the model requirements, and make sure the start and reverse functions operate smoothly.
