Comparable to Class 12.9 steel.

With threads the same diameter as the shoulder, these inch-sized screws can handle heavy loads. They’re comparable to Grade 8 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.

One-third the weight of steel, aluminum shoulder screws are lightweight and have good corrosion resistance.

Nickel alloy shoulder screws are more resistant to acids and salt water than stainless steel shoulder screws.

With a reduced head size and an unthreaded shoulder, use these screws as a shaft or dowel pin for small rotating parts in low-clearance applications.

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

A zinc plating provides mild corrosion resistance.

A locking element on the threads adds friction to resist loosening. Comparable to Grade 8 steel, these alloy steel shoulder screws are the strongest we offer.

These shoulder screws have good chemical resistance.

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

Tighten these shoulder screws by turning them to the left; once fastened, they resist loosening from counterclockwise motion.

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.

Comparable to Grade 8 steel, these screws are the strongest precision shoulder screws we offer.

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.
