Key Steel / Parallel Key:12 x 12 x 1 M

This parallel key is a precision-cut steel component designed to secure rotating machinery parts to shafts, transmitting torque between the shaft and the attached component. Manufactured from steel, it fits standard parallel keyways to ensure a secure mechanical connection. The specific dimensions of 12 mm width and 12 mm height identify this as a heavy-duty profile suitable for high-torque applications. Buyers select this product for its durability and reliable fit within industrial power transmission systems. The designation 1 M likely refers to the length or a specific grade variant, which should be verified against your equipment’s required key length to ensure proper engagement. Always confirm the shaft diameter and keyway dimensions match these 12 x 12 mm specifications before installation to prevent slippage or damage.
