Buttress threads manage very high axial thrust in a single path, which translates into high thread toughness.
Allen key push heads are applied greatly in field as they may be Employed in applications that require high amounts of torque.
You'll be able to tell torx head screws with the six pointed star on their own head. This means torx screws can cope with a lot more torque than most screws. Really, torque is where by they get their name, torx from. Just recall one thing, you’ll need to have a certain driver or little bit as a way to make use of them as a fastener.
