About Shoulder Screws

Slotted 18-8 Stainless Steel Precision Shoulder Screws
Made of 18-8 stainless steel, these shoulder screws have good corrosion resistance and may be mildly magnetic. With a shoulder diameter that is twice as precise as our general purpose shoulder screws, they provide smooth, accurate movement. Use them where precision matters, such as in measuring devices, optical fixtures, and laboratory equipment.
Passivated stainless steel screws have added protection against oxidation and corrosion.
