Vlier SSLRM12 Locking Knob Handle Plunger M12x1.75

Product Description

The VLIER SSLRM12 is a locking knob handle plunger with an M12x1.75 threaded body, designed for use in positioning, indexing, and locating applications across industrial and mechanical assemblies. The plunger features a countersunk knob style and delivers an initial end force of 1 pound, ramping to a final end force of 10 pounds, making it suitable for light-duty to moderate holding applications. The body length measures 16.5 mm (0.65 inches), and the maximum plunger diameter is 0.25 inches. Machinists, toolmakers, and maintenance technicians typically install these components in jigs, fixtures, and machine panels where repeatable manual positioning is required.

The SSLRM12 is suited for use in industrial machinery, assembly fixtures, tooling plates, and panel-mounted mechanisms where a threaded locking plunger provides controlled retraction and positive engagement. Its M12x1.75 thread makes it compatible with standard metric threaded bores in steel, aluminum, and similar structural components. This plunger type is commonly installed in manufacturing and fabrication environments where operators need to lock and release positioning elements by hand without additional tooling.

Key Features

• Locking plunger type with countersunk knob for flush or recessed installation
• M12x1.75 metric thread with 0.65 inch thread engagement length
• Initial end force of 1 pound, final end force of 10 pounds for controlled positioning resistance

• Plunger length of 1.40 inches and head diameter of 1.30 inches for compact fitment
• 6 mm hex size for installation and adjustment with standard hex tooling

Compatibility

Designed as an OEM-style replacement or new-install locking handle plunger for industrial fixtures, jigs, and machine assemblies using standard M12x1.75 metric threaded bores.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 6 mm hex wrench to thread the plunger body into a prepared M12x1.75 tapped hole. Ensure the mating bore is clean and free of debris before installation. Disengage or de-energize any associated machinery before servicing or replacing plunger components. Do not exceed the rated final end force by forcing the plunger beyond its designed travel range.
