Metric Alloy Steel Shoulder Screws
Comparable to Class 12.9 steel, these alloy steel shoulder screws are the strongest we offer. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment. Also known as stripper bolts, they're commonly used in punch and die assemblies, and as an axle or pivot point.

Metric Alloy Steel Thread-Locking Shoulder Screws
A locking element on the threads adds friction to resist loosening. Comparable to Class 12.9 steel, these alloy steel shoulder screws are the strongest we offer. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment. Also known as stripper bolts, they're commonly used in punch and die assemblies, and as an axle or pivot point.
