Metric Trapezoidal Nuts

Trapezoidal thread forms are screw thread profiles with trapezoidal outlines. They are the most common forms used for leadscrews (power screws).
They offer high strength and ease of manufacture and are typically found where large loads are required.
Example applications are a vise or the leadscrew of a lathe.
Nuts offered herein are all bronze but plastic and steel versions are available on request.
