Description

High-Precision Connecting Shaft and Threaded Block Assembly

Our connecting shaft and threaded block assembly is crafted for reliable mechanical connections and precise positioning in industrial applications. Engineered with strict tolerances, this assembly ensures smooth operation, stable alignment, and long-lasting performance.

Premium Materials and CNC Machining

The cylindrical shaft is machined from stainless steel or alloy steel, providing:

  • High load capacity

  • Corrosion and wear resistance

  • Long-term durability

The square threaded block is precision milled from solid metal stock, featuring:

  • Accurate internal threads

  • Square geometry to prevent rotation

  • Smooth chamfered edges for safe assembly

Advanced CNC turning and milling guarantee consistent dimensional accuracy and a polished surface finish for both components.

Customizable Dimensions and Thread Standards

We support full customization based on your technical drawings or samples, including:

  • Shaft diameter, length, and tolerance

  • Thread pitch, depth, and standard

  • Material type and heat treatment

  • Surface finishing options

This flexibility allows seamless integration into automation machinery, mechanical fixtures, industrial equipment, and custom tooling systems.

Reliable Industrial Applications

Widely used across:

  • Automation machinery and robotic systems

  • Mechanical transmission assemblies

  • Industrial equipment and precision fixtures
