Orion Hardened & Ground Parallel Pairs - 125x10x28mm

The ORION Hardened & Ground Parallel Pairs are precision blocks designed for parallel mounting of workpieces in machine vices, on machine tools, or fixtures. Supplied as a matched pair in a 125x10x28 mm size, they feature a 0.01 mm matching tolerance and a nominal tolerance of +/-0.02 mm to deliver consistent, parallel seating across setups.

These blocks are hardened and ground to resist wear and maintain flat, smooth contact surfaces, ensuring long-lasting accuracy even in demanding workshop use. Their precise pairing and robust construction make them a dependable choice for engineers, machinists, and hobbyists who need repeatable clamping with minimal setup time.

• Matched pair precision (0.01 mm): The two blocks are manufactured as a true pair with a 0.01 mm matching tolerance to ensure parallelism and repeatable clamping across setups.
• Hardened & Ground finish: Hardened steel and precise grinding deliver durable wear resistance and consistently flat seating surfaces for secure, long-lasting performance.
• Standard 125 x 10 x 28 mm size: Compact, standardized dimensions fit common vices and fixtures, enabling fast, confident positioning and reduced setup time.

With these parallel pairs, you gain reliable alignment, quicker setups, and improved consistency across parts. The tight tolerances help minimize rework and deliver better surface finishes, making them a practical upgrade for any machining workflow.
