Brass Precision Shoulder Screws

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