Vlier DBM6A Threaded Ball Plunger M6 X 1 Steel Nylon Ball

Product Description

The VLIER DBM6A is a threaded ball plunger with an M6 x 1 thread size, designed for use in indexing, positioning, and light-duty detent applications across mechanical assemblies. The body is constructed from zinc-plated steel, and the ball is nylon, measuring 0.138 inches in diameter with a maximum ball reach of 0.039 inches. Initial end force is 2.02 pounds and final end force is 2.92 pounds, making this plunger suitable for applications requiring controlled, repeatable positioning force. Body length is 0.551 inches. No locking element is included. The color code is purple for quick field identification.

This ball plunger is used in machine tooling, fixture design, jig assembly, and general industrial mechanical assemblies where a spring-loaded ball is needed to hold or locate a moving component. The M6 x 1 metric thread makes it compatible with standard metric threaded housings common in precision manufacturing and automation equipment. Typical installers include machinists, tool and die makers, and mechanical assembly technicians.

Key Features

• M6 x 1 metric thread for installation in standard metric threaded bores
• Nylon ball resists marring on delicate mating surfaces
• Zinc-plated steel body for corrosion resistance in light-duty environments
• 2.02 pounds initial end force and 2.92 pounds final end force for consistent detent action
• 0.039 inches maximum ball reach for precise positioning control
• Purple color code for rapid size and specification identification

Compatibility

Designed as a direct-fit replacement or new-installation threaded ball plunger for metric M6 x 1 threaded housings in mechanical fixtures, jigs, and tooling assemblies.

Installation Notes

Installation is performed by threading the DBM6A into a pre-tapped M6 x 1 metric bore using a hex key or appropriate driver on the body. Ensure the mating bore is clean and free of debris before installation. Do not overtighten, as excessive torque can compress the spring mechanism and reduce detent performance. No special certifications are required for installation, though standard shop safety practices apply.
