Orion Hardened & Ground Parallel Pairs - 100x4x12mm
Learn more about Klarna
Description
The ORION Hardened & Ground Parallel Pairs are precision blocks designed for true parallel mounting of workpieces in machine vices, on machine tools, or in fixtures. Measuring 100 x 4 x 12 mm, these blocks deliver reliable spacing and alignment for a wide range of setups.
For repeatable results, each pair features a strict tolerance plan: a matching pair tolerance of 0.01 mm and a nominal tolerance of +/-0.02 mm, helping you maintain consistent parallelism without guesswork.
- Precise matching pair tolerance: Each pair is ground to a 0.01 mm matching tolerance with a nominal +/-0.02 mm, delivering repeatable parallelism and reducing setup rework.
- Hardened and ground surfaces: Hardened steel with precision grinding provides durable, flat surfaces that resist wear and stay accurate through many cycles.
- Versatile, ready-to-use for common setups: Sized 100 x 4 x 12 mm and designed for machine vices, machine tools, or fixtures, enabling quick, reliable alignment with minimal fuss.
Using these parallel pairs helps you set up workpieces faster, maintain tight tolerances, and reduce scrap. The hardened, ground surfaces stay flat longer, delivering consistent clamping results across jobs and improving accuracy in milling, drilling, and inspection tasks.
