Product Overview

Steel Ball with Threaded Hole is a drilled and threaded spherical component designed for secure, economical mounting in fixtures, tooling, and measurement systems. Steel ball with threaded hole, mounted in a spherical cavity, and held in place with a threaded fastener is an effective mounting technique that is quite economical. This design allows the ball to be rigidly attached to a mating part while preserving the benefits of a spherical form for alignment, positioning, and mechanical interface needs. We stock a limited number of drilled and threaded balls.

Engineered and tested across thousands of installations based on decades of manufacturing expertise, these threaded steel balls are widely specified for measuring machines and machine tools where repeatable attachment, robust fastening, and stable surface quality matter. They support multiple surface treatments and optional services to fit industrial finishing requirements and integrated assembly designs.
