Wrenches and screwdrivers are popular tools in woodworking for tightening and loosening bolts, nuts, and screws. They are quite similar in usage, but there are significant differences.
This article mainly focuses on the basics of the manual wrench and the screwdriver, and the differences between the two. Let’s keep reading and get useful information.
What is a Wrench?
Wrenches are both hand tools and power tools to tighten or loosen fasteners like bolts and nuts by applying torque to ensure a tight connection. Its design usually consists of two jaws and a handle. Some adjustable wrenches have a worm screw for adjusting one jaw to fit different-sized fasteners.
The handle is used for gripping and applying force, and it is usually of a non-slip design. Jaws are used to grip nuts and bolts. They can be fixed (e.g. open-end wrench and box) or adjustable (e.g. adjustable wrench).
Pros and Cons of a Wrench
ADVANTAGES:
- Stability. Bolts and nuts are often used in woodworking furniture, like tables, chairs, and bed frames. The wrench can ensure fasteners are secure, adding stability to the furniture.
- High torque. It is ideal for tightening larger-sized fasteners that require high tightening forces.
- Easy to disassemble. For woodworking furniture that needs to be disassembled and reassembled, the wrench can quickly loosen fasteners, convenient for maintenance and handling.
- Wide range of applications. Different types of wrenches (like adjustable wrenches) can be used for different sizes and types of bolts.
DISADVANTAGES:
- Easy to damage wood. When tightening a nut on softwood, the nut may be overly embedded in the wood, causing cracks.
- Not applicable to no-bolt construction. Wrenches are not useful in some woodworking connections such as joints and gluing.
- Low efficiency. Manual wrenches are slow to operate when doing large and repetitive tasks.
What is a Screwdriver?
Screwdrivers are essential tools, usually manual, for turning screws with slotted heads. A simple screwdriver always consists of a handle, a shank (or shaft), and a drive tip. You can put the tip into the screw head and turn the handle to tighten and loosen the screws.
The most common screwdriver is the slotted screwdriver. For screws with special slots in the head (such as Phillips screws), a special screwdriver with a tip (Phillips screwdrivers) that matches the slot is required.
Pros and Cons of a Screwdriver
ADVANTAGES:
- Precision and accuracy. Manual screwdrivers provide precise torque control and are particularly suitable for screws that are small and require manual adjustment.
- No damage to the wood. Reduce the impact on the wood and lower the risk of cracking and damage to the wood.
- Portability. Lightweight and easy to carry, no need for power, suitable for outdoor carpentry or temporary work.
DISADVANTAGES:
- Low efficiency. Compared to an electric screwdriver or drill, a manual screwdriver operates at a slower speed and takes longer to tighten and loosen a screw.
- Laborious. It requires you to have greater hand strength and endurance, especially when working on hardwoods.
Distinguish the Wrench from the Screwdriver
In woodworking, wrenches and screwdrivers appear to serve the same function and are both used to tighten and loosen fasteners (bolts, nuts, screws, etc.). Both apply torque through leverage or rotational force to accomplish woodworking tasks. However, there are significant differences in their designs, usage scenarios and target objects.
Designs: The lever arm (handle) of the wrench is extended, resulting in high-torque output. Screwdrivers have shorter handles, so it’s suitable for low-torque and high-precision rotation.
Usage scenarios: Wrenches are more ideal for structural reinforcement and connection of large workbenches, such as table saws and router tables. Screwdrivers are the better choice when adjusting delicate components such as cabinet door hinges.
Target objects: Wrenches are mainly used for hexagonal or polygonal fasteners such as nuts and bolts, while screwdrivers are primarily used for rotating screws with slotted heads (slotted, Phillips, cross, Torx, etc.).
To Sum Up
In light of all the above, here’s a conclusion: both wrenches and screwdrivers are functional tools in carpentry, especially in operations that require tightening and dismantling. Wrenches offer strength and durability for heavy structures. Screwdrivers, on the other hand, offer flexibility and precision for delicate work.
FindBuyTool provides pro wrench versions - torque wrench set and T-handle preset torque wrench to help you finish various installation work. They apply a specific torque to a fastener. When the torque value reaches the preset one during the application, a click sound will remind you.
