WebThis is part of a series on common misconceptions.. What is \(\frac00?\) Why some people say it's 0: Zero divided by any number is 0. Why some people say it's 1: A number divided by itself is 1. Only one of these explanations is valid, and choosing the other explanations can lead to serious contradictions. WebAlloy Steel Thread-Locking Socket Head Screws. With a tensile strength of 170, 000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and are nearly two and a half times stronger than stainless steel thread-locking screws. They have a thread locker to prevent loosening from vibration.
