Built with ground steel legs and a polished finish, this tool delivers consistent accuracy for machinists, pipefitters, fabricators, and tool-and-die technicians. The spring joint mechanism maintains tension across the full range of adjustment, keeping the set position stable under repeated use. With a leg length of 6 inches and a maximum measurement capacity of 6 inches (150 mm), the 51311 handles a wide range of common layout tasks without needing to reset. The solid nut provides secure locking once the desired spacing is established.\u003c\/p\u003e\u003cp\u003eThis divider is suited for use in machine shops, fabrication environments, and trade applications where precise scribing or circle layout is required. It is a standard hand tool carried by machinists, pipefitters, sheet metal workers, and precision layout technicians. The 6-inch leg length makes it appropriate for medium-range layout work on both flat stock and curved surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpring joint design maintains consistent leg tension throughout the adjustment range\u003c\/li\u003e\n\u003cli\u003eGround steel construction for dimensional accuracy and durability\u003c\/li\u003e\n\u003cli\u003ePolished finish reduces surface friction during scribing\u003c\/li\u003e\n\u003cli\u003e6-inch leg length with 6-inch (150 mm) maximum measurement capacity\u003c\/li\u003e\n\u003cli\u003eSolid nut for positive, stable locking at set position\u003c\/li\u003e\n\u003cli\u003eRound leg profile for clean, precise scribe lines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard spring joint divider for general precision layout and scribing applications in machining, fabrication, and trade use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo power source or mechanical installation is required for this hand tool. Set the desired leg spacing using the spring joint adjustment and secure with the solid nut before scribing. Keep legs clean and lightly oiled to maintain smooth adjustment and prevent corrosion.
