Spindles with metric threads are used as drive or movement threads as well as fastening threads. This type of thread is also known as ISO thread, ISO metric thread, normal thread, pointed thread, metal thread or machine thread.
The outer edges of the metric thread converge in a wedge shape. Metric threads are self-locking. The flank angle is 60 degrees.
Depending on the pitch, a distinction is made between standard, coarse and fine threads.
Metric threads are mainly used in dynamic applications (drive spindles) when small diameters and / or small pitches are required. Metric spindles are also very common, which is why production is usually very economical.
Compared to trapezoidal screw drives, metric screw drives have a poorer efficiency and higher wear. The trapezoidal thread is therefore preferable for high speeds or very high mileage.
We supply metric drive / movement threads in various diameters and pitches. The threaded spindles also differ in their direction of rotation, accuracy, material, surface treatment, length and possible journal machining.
Typical designs for metric threaded rods as fastening threads are studs, double ends, threaded pieces, threaded rods, anchor screws, anchor bolts, weld-on ends. Threaded shafts and tie rods.
