If your strap wrench doesn’t have printed arrows, then position it so the flat section is on the left if you’re tightening or on the right if you’re loosening.
Nylon and rubber straps work best when you don’t want to damage or mar the surface of the object. Metal straps are heavy-duty and give you more leverage, but they tend to scuff the surface of whatever they touch.
Hold the end of the strap tightly against the handle to help prevent it from going slack. [5] X Research source
Cheap belts or belts with small buckles may break when you pull on them.
Press the tape down firmly against the sides of the nut or bolt to make sure it doesn’t come loose when you’re trying to unscrew it.
You could instead attach a piece of duct tape to the end of the strap and attach it to the object. Wrap the strap around the object a few times and then pull on the loose end of the strap to screw or unscrew the object. [9] X Research source
