Okokusetshenziswa nama-torque wrenches angenayo igeji ye-angular eyakhelwe ngaphakathi. Inika amandla ukufundwa kwenani lamadigri "emva kokuqinisa" lapho iqina kwezinye izinhlelo zokusebenza lapho i-engeli idinga ukulinganiswa(amabhawodi wokwelula, njll). Indawo emile yokufunda, uzibuthe olungisayo kanye nezikali ze-engeli kwenza kube nokwenzeka ukufunda ezimweni eziningi.
