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.

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.

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

Available in metric sizes, these screws have a locking element on the threads that adds friction to resist loosening. Comparable to Grade 8 steel, they are the strongest screws we offer.

More corrosion resistant than 18-8 stainless steel shoulder screws, these have excellent resistance to chemicals and salt water.

Made from alloy steel, these metric set screws have a thin edge that digs into hard surfaces for a secure hold. They have a nylon locking patch that grips threads to resist loosening.

These 18-8 stainless steel set screws are chemical resistant. They have a nylon locking patch that grips threads to resist loosening.

A nylon locking patch grips threads to resist loosening.

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