【トルクレンチなし】車載工具で正確に締める『手ルクレンチ』のすすめ

I tighten the wheel nuts on my tires by feel using the wrench from my car's tool kit. I measure the torque with a bathroom scale! I experience this feeling and develop my "hand torque wrench." The important thing isn't the torque itself, but the process of tightening each nut evenly. I believe that hand-tightening, seating the nuts, and intuitively grasping the hand torque to feel the axial force of the bolts is crucial for safety. I'm not saying you shouldn't use a torque wrench (lol). I just think, "What are they talking about?" to torque wrench supremacy and the torque wrench police. "Blind faith" is dangerous. Torque wrenches can be inaccurate, and the feel of a hand torque wrench can also be unreliable. It's by "doubting" both equally that we can become cautious and repeatedly perform thorough inspections. 【Listen to the Bolts】 In the video, I introduce methods based on my own thoughts and experience, including not just tightening, but also "the feeling of a bolt stretching by 0.2mm" and "calibrating the feeling using a bathroom scale." A hand torque wrench is a tool for listening to the bolts. [Important Safety Information - Please Read Carefully] Use at Your Own Risk: I take no responsibility for any accidents or incidents that may occur using this method. However, I do not believe this method is dangerous or irreproducible, and I recommend it, which is why I have made this video. A manual torque wrench is not meant for lazily tightening nuts; it's for honing your feel for tightening, and even for questioning your own feel. This undoubtedly contributes to safety. For safety, jack up the vehicle on a level, hard surface, put it in P (park), engage the parking brake, place the tires under the body, and place wheel chocks on opposite wheels. Check the manufacturer's specified jacking points in the owner's manual. When tightening, ensure the wrench completely covers the nut to prevent it from slipping. Do not use momentum or force when tightening. Apply force gradually. When loosening, the wrench may suddenly turn, so it is safer to pull rather than push. * The video says to divide the value by 10 when converting N to kg (more precisely, kgw), but the correct way is to divide by 9.8. Dividing by 10 results in only a 2% error, so it was said to divide by 10 for easier intuitive understanding. The unit of force is kgw, but kg is used for the same reasoning. The car is a Suzuki Every DA17V. The video says to hold the wrench long and turn it with 40 kgw, but of course, this may not be true depending on the car model. The concept is the same, so please recalculate according to your car. However, I don't think it will be significantly different. In the video, there are scenes where the left hand is resting near the nut, but to get an accurate reading, you need to hold the wrench horizontally and put your weight only on the end.
