The Suitable Torque for Household Electric Screwdrivers

Introduction

Household electric screwdrivers are essential tools for DIY enthusiasts and professionals alike. Choosing the right torque is crucial for ensuring efficiency and preventing damage to materials or screws. This report will discuss the suitable torque for household electric screwdrivers and provide an overview of various brands and models that cater to different needs.

Understanding Torque in Electric Screwdrivers

Torque, measured in Newton-meters (N.m), determines the rotational force applied by the screwdriver. For household use, the ideal torque range varies depending on the application.

• Low Torque (1-5 N.m): Suitable for light-duty applications such as assembling furniture, installing electronic devices, or working with softwood.
• Medium Torque (5-10 N.m): Best for general home repairs, including mounting shelves, fixing hinges, and working with medium-density materials.
• High Torque (10-30 N.m): Needed for heavy-duty household tasks like drilling into hardwood, metal, or dense plastic materials.

Recommended Torque for Household Tasks

1. Assembling Furniture: 3-5 N.m
2. Hanging Pictures and Frames: 2-4 N.m
3. Fixing Door Hinges: 5-8 N.m
4. Installing Light Fixtures: 3-7 N.m
5. Drilling Small Holes in Wood: 8-15 N.m
