                                                Features
Trapezoidal   thread T ISO Trapezoldal Thread:For transmission and posltion adjustment, wldely used  In the  mechanical Industry.
Metric thread M ISO Metric Thread (60° ):The most common form of thread used for fastening   and  precislon transmission.
ACME thread English threads can also be used for fastening connectlons,but not for high accuracy

Design Considerations

Most applications can be satisfied by selecting from ALM stock sizes listed. However, OEM may find an optimum design solution requiring a special size or special features such as stub series threads, special diameter and lead combinations, multiple start thread, etc. For these applications, ALM is uniquely qualified with over 15 years of experience in serving the OEM market. Extensive tooling and software resources can be utilized to assist the OEM designer in finding the very best metric solution for any application. Contact ALM Application Engineering for more details.


Nut Selection

When selecting the right nut for an application, there are a few things to keep in mind. Bronze nuts provide superior service at high working loads. They should be well lubricated with a good quality, Extreme Pressure (EP) grease compatible with the operating environment. Plastic nuts can be used without lubrication and are popular for low load applications.


Trapezoidal lead screws and nuts are widely used and well suited for both manual and power drive applications including:

Pharmaceutical machinery

Packaging machinery

Slide drives

Metric valve stems

Medical device drives

Farm machinery

Screw press drives
