About Shoulder Screws

Alloy Steel Shoulder Screws

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

Metric Alloy Steel Shoulder Screws

Comparable to Class 12.9 steel.

Short-Thread Alloy Steel Shoulder Screws

Use these screws in thin materials; they have a shorter threaded portion than our standard shoulder screws. They’re comparable in strength to Grade 8 steel.

Same-Size Thread Alloy Steel Shoulder Screws

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

Metric Same-Size Thread Alloy Steel Shoulder Screws

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

Alloy Steel Shoulder Screws with Material Certification

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

Metric Slotted Low-Profile 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.

Low-Profile 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.

Metric Low-Profile Shoulder Screws

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.

Ultra-Low-Profile Shoulder Screws

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

Metric Steel Hex Head Shoulder Screws

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.

Steel Hex Head Shoulder Screws

A zinc plating provides mild corrosion resistance.

Alloy Steel Thread-Locking Shoulder Screws

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.

Metric Alloy Steel Thread-Locking Shoulder Screws

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.

Headless Alloy Steel Precision Shoulder Screws

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.

Alloy Steel Precision Shoulder Screws

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

Steel Shoulder Screws for Binding Barrels

Designed with a shoulder for the strength to handle side and shear loads.

Shoulder Screw Assortments

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.

Lock Screws for Removable Locating Pins

Secure removable locating pins. The head of the lock screw fits into the notches on the shoulder of the pin.
