Orion Hardened & Ground Parallel Pairs - 150x12x40mm

ORION Hardened & Ground Parallel Pairs, sized 150x12x40 mm, are precision blocks designed for parallel mounting of workpieces in machine vices, milling machines, and fixtures. The pair is engineered to stay parallel under clamp loads, delivering reliable, repeatable results across multiple setups. With a hardened and ground finish, these blocks resist wear and keep their flatness and alignment over time.

They feature a matching pair tolerance of 0.01 mm and a nominal tolerance of +/- 0.02 mm, providing tight, dependable parallelism whenever you need precise workholding. Whether you’re a professional machinist, an engineer setting up prototype runs, or a hobbyist building jigs, these parallel pairs simplify alignment and reduce setup time.

• Matched pair tolerance of 0.01 mm: Ensures both blocks sit parallel to each other and to the workpiece, delivering repeatable clamping performance across repeated uses.
• Hardened & ground surfaces: Provide long wear life, maintain flatness, and resist denting or indentation from workholding forces, keeping accuracy intact even in demanding environments.
• Compact, standard size (150 x 12 x 40 mm): Fits most machine vices and fixtures for quick setup, easy handling, and versatile usage across milling, drilling, and assembly tasks.

Using these parallel pairs helps you align workpieces quickly and securely, improving setup efficiency, reducing rework, and ensuring consistent results from part to part. The combination of precise tolerance, durable construction, and standard sizing gives you reliable performance in both professional shops and detailed hobby projects.
