Among the different types of wrenches, it is one of the most common in furniture and bicycle assembly.

• Special feature/design: L-shaped hex rod for tight spaces and leverage
• Best used for: Furniture assembly, bicycles, electronics

2.8 Torque wrench

A torque wrench is a precision tool used to apply a specific amount of torque to a fastener. It often features a scale or clicking mechanism to indicate when the desired torque level is reached. This makes it essential for tasks where accuracy is critical, especially in automotive and machinery applications.

• Special feature/design: Adjustable torque setting with click or digital indicator
• Best used for: Precision tightening, engine and mechanical work

2.9 Pipe wrench

A pipe wrench is a heavy-duty tool designed specifically for gripping and turning pipes. It features adjustable serrated jaws that tighten around round surfaces, providing a strong and secure hold. This makes it one of the most reliable types of adjustable wrenches for plumbing work.

• Special feature/design: Serrated adjustable jaws with strong gripping power
• Best used for: Plumbing, metal pipes and fittings 

2.10 Strap wrench

A strap wrench uses a flexible strap made from rubber, nylon, or fabric to grip objects without damaging them. It wraps around smooth or irregular surfaces and tightens as force is applied. This makes it ideal for delicate materials that standard metal wrench types might scratch.

• Special feature/design: Adjustable strap for non-damaging grip
• Best used for: Plastic pipes, jars, polished or delicate surfaces

3. Specialized, heavy duty types of wrenches

When standard tools are not enough, specialized types of wrenches come into play. These tools are engineered for tasks requiring higher torque or unique access solutions.
