Vlier DSBMH12 Threaded Ball Plunger M12 X 1.75

Product Description

The VLIER DSBMH12 is a threaded ball plunger designed for indexing, positioning, and light detent applications in industrial and mechanical assemblies. It features an M12 x 1.75 thread, a stainless steel body for corrosion resistance, and a nylon ball that provides smooth, low-friction contact against mating surfaces. The body measures 0.866 inches in length with a maximum ball reach of 0.098 inches. Initial end force is 16.86 pounds and final end force is 25.85 pounds. A locking element is built into the design to secure the plunger position once set. This component is typically installed by machinists, tool and die technicians, or mechanical assemblers working on fixtures, jigs, and precision equipment.

This ball plunger is suited for use in machine tool fixtures, assembly jigs, automated equipment, and mechanical indexing mechanisms where a repeatable detent action is required. The nylon ball minimizes surface marring on softer mating materials. The M12 x 1.75 threaded body allows direct installation into standard tapped holes in steel, aluminum, or plastic housings. The purple color code aids quick identification during assembly and maintenance.

Key Features

• M12 x 1.75 threaded body for direct installation into standard tapped holes
• Stainless steel body provides corrosion resistance in demanding environments
• Nylon ball reduces surface marring on delicate or soft mating materials
• Built-in locking element secures plunger adjustment after setting
• 16.86 pounds initial end force and 25.85 pounds final end force for consistent detent performance
• Purple color code for fast field identification

Compatibility

Designed as a direct-fit threaded ball plunger for assemblies requiring an M12 x 1.75 tapped hole. Suitable for use in machine tool fixtures, positioning jigs, and mechanical indexing applications where a nylon-ball, locking-style plunger is specified.

Installation Notes

Installation requires a properly tapped M12 x 1.75 hole in the mounting body. Disengage or de-energize any powered equipment before installing or adjusting the plunger. Use an appropriate hex key or spanner to thread the plunger in to the desired depth, then engage the locking element to hold position. Avoid overtightening, which can deform the nylon ball or damage the thread engagement.
