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 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.

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.

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

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.
