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 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.

Made of lubricant-filled nylon, these screws have a slippery surface to resist wear in high-friction applications.

Titanium shoulder screws have a high strength-to-weight ratio and are more resistant to acids and salt water than nickel shoulder screws.

The head height of these screws is about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

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.

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.

Stainless steel shoulder screws have excellent corrosion resistance in most environments.

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.

Screw these shoulders onto a stud.

With a hex socket at the tip as well as the head, you can fasten these shoulder screws from the tip when the head cannot be reached.

With a shoulder that’s twice as precise as standard shoulder screws, these metric shoulder screws act as a shaft or axle for bearings and other moving parts in applications that require smooth and accurate movement, such as measuring and lab equipment. Made of 18-8 stainless steel, they’re nearly as strong as steel but won’t rust in outdoor or washdown environments.

Install and remove these shoulder screws by hand or with a hex key.

These metric 316 stainless steel shoulder screws are more corrosion resistant than 18-8 stainless steel shoulder screws. They also have excellent resistance to chemicals and salt water.

Made of 416 stainless steel, these shoulder screws are almost twice as strong as 18-8 stainless steel and have the same corrosion resistance.

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.

Offered in metric sizes, these brass shoulder screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

These screws have a head height about one-third the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.
