ACME screw and trapezoidal screw are both trapezoidal thread lead screw,while they look similar,they have distinct differences.
ACME screw thread design /strength /common uses/standards:
(1)Thread Design: ACME thread screws have a 29-degree thread angle and is manufactured in inch dimensions.
(2)Strength: ACME lead screw is designed for heavy loads and high durability.
(3)Common Uses: Machine tools,CNC systems, lifts,and automotive jacks.
(4)Standards: Follows ANSI/ASME standards (common in the U.S.).
Trapezoidal screw thread design/strength /common uses/standards:
(1)Thread Design: Trapezoidal lead screws have a 30-degree thread angle and are manufactured in metric dimensions.
(2)Strength: Trapezoidal screw is used for lighter to medium loads.
(3)Common Uses: 3D printers,conveyor systems,and European/Asian machinery.
(4)Standards: Follows ISO metric standards (common outside the U.S.).
Trapezoidal screw and ACME lead screw differences summary
Feature | ACME Screw | Trapezoidal Screw |
