3/16" Steel Balls Grade 10 (Pack of 2000) – Engineered for Elite Performance
When you're working on projects where precision isn’t optional, you need components that deliver with confidence. These 3/16" Grade 10 steel balls are designed for demanding applications that require exact dimensions, exceptional durability, and long-lasting performance. With a diameter of 4.76 mm, each ball is manufactured using hardened high-carbon steel, refined to meet Grade 10 tolerance standards — which translates to superior roundness, smoothness, and consistency.
🔧 Engineered for Precision
What sets these balls apart is their Grade 10 rating — which means tighter tolerances and better performance under stress. With a sphericity deviation of less than 10 microns, these balls roll with extraordinary balance and smoothness. Each one is heat-treated for toughness and mirror-polished for a frictionless finish. They’re manufactured to ISO 3290 standards, making them ideal for high-performance industrial use.
