ACME Threaded Rod

ACME Threaded Rod is a strong, durable rod with a trapezoidal thread profile, developed in the 1890s to replace square and other formed threads. Known as the American trapezoidal thread—not an abbreviation—ACME threads are designed for smooth, high-load linear motion in tools and machinery. Their broad thread surface provides better load distribution, reduces wear, and extends service life, making them ideal for applications involving frequent disassembly and reassembly.
