These shoulder screws are angled under the head to sit flush in countersunk holes. Use them in structural and load-bearing applications, such as attaching panels to a surface. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment.

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. With a shoulder diameter that is more precise than our general purpose shoulder screws, these screws are a good choice for measuring devices, optical fixtures, laboratory equipment, and other applications where precision matters. Made of alloy steel, they are strong and resist wear. All meet DIN 927, an international standard for slotted shoulder screw dimensions.
