Comparable to Class 12.9 steel.

The metric-sized threads on these screws are the same diameter as the shoulder. Comparable in strength to Class 12.9 steel.

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

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 have a head height about one-third the head height of a standard shoulder screw.

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.

Also known as wheel and axle bolts, these metric screws have an unthreaded shoulder that acts as a shaft, so material attached to the threaded end can rotate.

Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount, or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components.

Shoulder screws have a cylindrical shoulder under the head that allows parts to rotate around or slide along its length. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment.
