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

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.

The epoxy adhesive on the threads provides twice the holding power of standard thread-locking screws, but requires time to harden.

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.

Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are more than twice as strong as our stainless steel thread-locking screws. The thread locker helps resist loosening from vibration.
