What Does ACME Stand for in Threads?

The ACME thread form, featuring a 29-degree thread angle, provides a strong, durable, and efficient threading system ideal for power transmission and heavy-load applications. These characteristics make High-Quality ACME Threaded Products essential components in demanding industrial settings.

What is an ACME Threaded Rod?

An ACMEthreaded rod is a long, straight metal rod with ACME threads running its length. These rods are essential in various mechanical applications, such as lead screws for machinery, linear actuators, and jacks. They offer superior load-bearing capacity and reduced backlash, making them a preferred choice in precision machinery.

Types of ACME Threaded Products

ACME threaded products come in various forms, each designed for specific applications. Common types include:

Standard ACME Threads: Widely used for general-purpose lead screws.

Stub ACME Threads: Have a shallower depth and are used where space constraints exist.

Centralizing ACME Threads: Designed to reduce backlash by ensuring more accurate alignment.

ACME Thread Chart and Dimensions

Understanding the dimensions of ACME threads is crucial for selecting the right product for your needs. Here is a detailed ACME thread chart:

• Pitch Diameter: The diameter of the thread at which the width of the thread and the space between threads are equal.
• Thread Height: 0.5 x Pitch (The height from the root to the crest of the thread.)
• Thread Angle: 29 degrees (The angle between the sides of the thread measured in an axial plane.)
• Lead: The distance a nut will travel parallel to the screw axis in one revolution.
• Root Diameter: The diameter at the base of the thread.
