Translating step 3

Step 3
Bits with the prefix "J" and "PH" are often thought to be the same bit. Don't be fooled by their similar appearance—they are quite different. Phillips (PH) screws are designed to make a Phillips screwdriver cam out if too much torque is applied. This prevents damage to screws and screwdrivers or bits.
J vs PH
  • Bits with the prefix "J" and "PH" are often thought to be the same bit. Don't be fooled by their similar appearance—they are quite different.

  • Phillips (PH) screws are designed to make a Phillips screwdriver cam out if too much torque is applied. This prevents damage to screws and screwdrivers or bits.

  • Japanese Industrial Standard (J) screws do not provide a cam-out option, and have 90 degree corners.

  • J (JIS) and PH (Phillips) driver bits are not always interchangeable. As you can see, they do not share identical physical properties.

Spesso le punte con prefisso "J" e''' "PH" sono ritenute essere la stessa punta. Non farti ingannare dalla loro forma simile: sono abbastanza diverse.

Le viti Phillips (PH) sono fatte apposta per far sì che un cacciavite Phillips salti fuori se viene applicata troppa coppia. Questo previene danni alle viti e ai cacciaviti o punte cacciavite.

Le viti con Standard Industriale Giapponese (J) non prevedono questa fuoriuscita del cacciavite, e hanno angoli a 90 gradi.

J (JIS) e PH (Phillips) non sono sempre intercambiabili. Come puoi vedere, non condividono le stesse proprietà fisiche.
