A sixty% thread may very well be ideal in cases where substantial tensile loading won't be expected. In both of those cases, the pitch diameter is not really influenced. The balancing of truncation versus thread energy is analogous to numerous engineering conclusions involving the toughness, bodyweight and price of fabric, and also the Charge to equipment it.
Obviously, you continue to should be thorough when employing a Phillips screw mainly because if you employ a lot of pressure, you'll be able to strip the head swiftly, which means you may have to get started on about with that exact component of your challenge.
