Spring Dividers — IMPA 650231-650237

Spring dividers in the IMPA 650231–650237 range are standard marking and scribing tools carried on board cargo ships, container vessels, tankers, bulk carriers, and offshore support vessels. They are used in the engine room, deck workshop, and steel fabrication areas for transferring measurements, scribing circles and arcs, and marking layout lines on iron and steel surfaces before cutting, drilling, or fitting. The hardened steel points hold a sharp line on metal, which helps the crew produce accurate repair parts and structural markings without guesswork.

Each divider is made from hardened steel, with the two points additionally tempered so they can scribe directly onto iron surfaces without rapid dulling. A rigid spring holds the legs under tension, and the quick-adjust locking screw lets the user set and lock a dimension in seconds. This combination of spring tension and positive locking keeps the setting stable during use, which is important when the tool is passed between hands or used in a moving engine room environment. The full series covers 7 individually ordered IMPA codes, 650231 through 650237, so purchasing officers and chief engineers can order the exact size or leg length required by their planned maintenance or tool list. Every code in the range is available and priced individually.
