1. How many series or models does WYMA's Pneumatic Screwdriver have? What are they commonly used for?

WYMA® makes four main series of Wholesale Air Screwdrivers, which are the Straight Type series, the Pistol-grip series, the Right Angle series and the Inline Torque series. 

What distinguishes the Straight Type from the Pistol-grip is essentially how you hold them, a choice that boils down to personal preference. Their torque, which spans from 60N.m to 155N.m, suits general factory work, furniture assembly, or automotive and machinery maintenance where you need to drive screws. 

The Right Angle series has a 90° elbow body that lets you work in tight corners and confined spaces that other tools cannot reach. 

As for the Inline Torque series, it lets you preset multi specific torque levels, a feature that makes it suitable for delicate electronics and high-precision instruments whose assemblies require a controlled torque range from 0.5N.m to 2N.m.

2. I don't want to damage the motherboard and the screws on it anymore. Is there any way to solve this problem?

This situation is usually caused by the screwdriver's torque being too large, and the screwdriver has not stopped when the screw reaches the max tightening position. That’s why we suggest using the WM-3112 model or WM-3113 model Air Inline Torque Screwdriver, which is built for high-precision assembly work like fastening screws in electronics and delicate instruments. You can set a specific torque level on this tool, and it starts as soon as you press it down on the work pieces. Once the torque reaches the preset limit, it stops immediately—so it won't damage the screw or the device. This screwdriver has four torque settings: use setting Gear 2 for screws that are 1.5mm in diameter, setting Gear 4 for those that measure 2–3mm, setting Gear 6 for 3–4mm screws, and setting Gear 8 when you’re working with 4–5mm screws.

3. I want to use it for a long time. Are there any replaceable internal parts? What are the replaceable screwdriver bits?

Of course! We offer the parts shown in the pictures below. We also offer a variety of screwdriver bits, including slotted bits, phillips bits, hex bits or sleeves and torx bits. These all perfectly match our products, allowing you to easily handle screws with a variety of head shapes.

4. What are the main specs of an Air Screw Driver? What do they represent and reflect?

There are only two main specifications: Max Torque and Bolt Capacity.

Max Torque is the most important parameter of a pneumatic screwdriver. It represents the upper limit of the output rotational torque and directly determines how tight the screw can be tightened. People usually measure it in N·m. This parameter gives you a clear understanding of the tool's fastening capacity and what kind of work pieces it can handle. For instance, putting together delicate electronics requires low, precise torque, while assembling heavy machinery needs a much higher torque. When you look at a product catalog and see a torque range, just make sure the torque you need for your work falls within that range.

Bolt Capacity tells you the range of screw diameters the tool is meant to work with, and it's given in mm. It is a very intuitive selection indicator to choose the right tool, because it shows exactly what size screws the driver can take. If a air screwdriver indicates it's for M4 to M5 screws, that means it’s the right choice for screws that have a head diameter between 4mm and 5mm.

5. What are the material compatibility of these screwdrivers? What materials can they be screw tapped on?

Our screwdrivers have extremely powerful output and can be used for screw tapping common construction materials. The applicable materials are shown in the following pictures.
