Made from 18-8 stainless steel, these inch-sized shoulder screws have good chemical resistance.

For metric thread sizes with excellent resistance to chemicals and salt water, choose these 316 stainless steel shoulder screws.

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.

Comparable in strength to Grade 8 steel. These screws have inch thread sizes.

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

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

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

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

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.

A zinc plating provides mild corrosion resistance.

Screw these shoulders onto a stud.

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

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.

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.

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 metric 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.

Brass shoulder screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

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

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.

More corrosion resistant than 18-8 stainless steel bolts, these bolts have excellent resistance to chemicals and salt water. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

About half the strength of medium-strength bolts, these Grade 2 bolts are for light duty fastening. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

Bronze bolts are resistant to salt water, electrically conductive, and nonmagnetic. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

These bolts are suitable for fastening most machinery and equipment. Carriage bolts have a smooth, rounded head for a finished look. The knurled neck grips the inside of the hole to keep these bolts from turning when tightening a nut.

Made from Grade 5 steel, these bolts are suitable for fastening most machinery and equipment. These bolts are commonly used in tight spaces with moving parts, such as grain elevators and other belting systems, because the smooth, low-profile head provides a flush fit when installed. The square neck keeps these bolts from turning when tightening a nut.

Ribs under the head dig into the surface of soft metal and plastic to keep these bolts from turning when tightening a nut. Commonly used in tight spaces with moving parts, such as grain elevators and other belting systems, elevator bolts have a smooth, low-profile head that provides a flush fit when installed.
