Diameter 16mm Lead 2mm T16 Trapezoidal Tr16x2 Lead Screw.Due to the gap or clearance between the screw and the nut,the gap can affect the repeatability of the screw assembly,preventing it from returning to the same position after repeated movements.A common way to eliminate the gap between the lead screw nuts is to add a spring or other flexible component(such as a washer)between the two nut halves.Other methods use rigid gaskets that expand or move relative to one half of the nut and continuously compensate for the gaps that arise as the nut wears down.

Lead Screw Applications |
What’s the difference between lead screw designs? |
In power transmission applications,there are two main types of screw drives:screw drives that use a recirculating ball or roller for applications requiring high rigidity,excellent positioning accuracy,and high duty cycle ratio,and screw drives that rely on sliding contact for applications requiring corrosion resistance,self-locking operation,and customizable nut designs.
The second type - screw drivers with sliding contact between the nut and the screw shaft - is called lead screw,Acme screw or trapezoidal screw.Although these names are often used interchangeably,they actually refer to different screw geometrics and sizes.Here is a breakdown of the different types of sliding contact screws and what the terms"lead screw," "Acme screw," and "trapezoidal screw" really mean.
Lead Screws
The most commonly used of the three terms "lead screw" refers only to a powered screw that relies on the sliding motion between the nut and the screw shaft.There are two variations of the lead screw:the screw with square thread and trapezoidal thread.
Lead screw designs for power transmission use almost exclusively trapezoidal threads,which are easier to manufacture and have higher load capacity than screws with square threads.However,trapezoidal threads do have higher friction and are therefore less efficient than the square thread form.
The lead screw can have square or trapezoidal threads.
A power screw is a screw that transmits power by converting rotating motion into linear motion.The lead screw and ball screw are the types of power screws.
ACME Screws
As mentioned above,the lead screw for power transmission uses the trapezoidal thread form.But the trapezoidal screw design can be threaded at 29° or 30° angles,which means that the trapezoidal screw comes in two versions.
The first version(called the Acme screw)has a thread angle of 29° and is manufactured in inch size.Acme screw size is usually specified by the screw shaft diameter and the number of threads per inch or TPI.
Trapezoidal screw form with thread angle of 29°is called Acme screw,while trapezoidal screw form with thread angle of 30°is called trapezoidal screw.
Trapezoidal Screws
Trapezoidal screws also use the trapezoidal screw form of lead screw,but the trapezoidal screw thread angle is 30° and manufactured in metric size.The size of the trapezoidal screw is specified by the shaft diameter of the screw and the pitch of the screw thread.Trapezoidal screws are sometimes called "metric screw" or "metric Acme screw".
Acme screws and trapezoidal screws both use a trapezoidal thread form,but they have different thread angles.
