Product details
An Acme thread is a type of screw thread with a trapezoidal shape, characterized by a 29-degree flank angle and flat top and bottom. It's designed for applications involving power transmission and motion, like in lead screws and jack screws. Acme threads are known for their strength and wear resistance, making them suitable for heavy-duty applications. Here's a more detailed breakdown: Key Features of Acme Threads: Shape: Trapezoidal with a 29-degree flank angle. Function: Primarily used for transmitting force and motion, not for clamping or holding. Advantages: Strength: The wider, flatter thread shape provides a stronger base than V-shaped threads. Wear Resistance: The wider threads dissipate stress better and are less prone to stripping or cross-threading. Manufacturing: Generally easier to machine than square threads, which were previously common. Applications: Lead screws. Jack screws. Vises. CNC systems. Lathes, milling machines, and presses. Variations of Acme Threads: General Purpose: Standard threads for general applications. Stub-Acme: Shortened or "stubbed" threads for smaller spaces. Centralizing: Designed with restricted clearance to prevent wedging on the flanks.
