Vlier SBML12N Threaded Ball Plunger M12 X 1.75 Ss

Product Description

The VLIER SBML12N is a threaded ball plunger with an M12 x 1.75 thread size, designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The body and ball are both constructed from stainless steel, providing corrosion resistance in demanding environments. The ball diameter measures 0.315 inches (8.00 mm) with a maximum ball reach of 0.098 inches (2.50 mm) and a body length of 0.866 inches. Initial end force is 2.25 pounds (10.00 N) and final end force is 4.50 pounds (20.00 N). A locking element is integrated into the body to secure the plunger in the threaded bore after installation. This component is installed by maintenance technicians, machinists, and mechanical assemblers.

The SBML12N is suited for use in jigs, fixtures, tooling plates, and precision mechanical assemblies where repeatable ball detent action is required. The M12 x 1.75 thread makes it compatible with metric-threaded bores in machine frames, fixture bodies, and industrial equipment. The stainless steel construction makes it appropriate for wash-down environments, food-processing equipment, and other applications where corrosion resistance is a priority. The locking element prevents the plunger from backing out under vibration or repeated cycling.

Key Features

• M12 x 1.75 metric thread for direct installation into standard metric-threaded bores
• Stainless steel body and stainless steel ball for corrosion resistance
• 0.315 inch (8.00 mm) ball diameter with 0.098 inch (2.50 mm) maximum ball reach
• 2.25 pound (10.00 N) initial end force and 4.50 pound (20.00 N) final end force for controlled detent action
• Integrated locking element secures plunger position after installation
• Purple color code for quick field identification of force rating and size

Compatibility

Designed for installation into metric-threaded bores requiring an M12 x 1.75 thread profile; suitable for use in jigs, fixtures, tooling, and general industrial mechanical assemblies.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a standard hex wrench or spanner appropriate for the M12 body. The threaded bore should be clean and free of debris before installation. Engage the locking element per the manufacturer procedure to prevent the plunger from loosening under vibration. Do not exceed the rated end force by substituting higher-force springs or modifying the internal components.
