A nylon patch bonded to the threads adds friction to prevent loosening from vibration. Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic.

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

A nylon patch bonded to the threads of these metric screws adds friction to prevent loosening from vibration. Made of 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws.

These screws have good chemical resistance. A thread locker bonded to the threads prevents loosening from vibration.

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.
