These shoulder screws come with a traceable lot number and material test report. Similar in strength to Grade 8 steel.

These screws have metric thread sizes. They are 18-8 stainless steel for good chemical resistance.

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

Shoulder screws made of 17-4 PH stainless steel are nearly twice as strong as 18-8 stainless steel and have the same corrosion resistance. These screws have inch thread sizes.

These metric screws have a head height that's about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

These shoulder screws are angled under the head to sit flush in countersunk holes.

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.
