Gibraltar MSDKL38-PT-G Locking Knob Handle Plunger M10x1.5

Product Description

The GIBRALTAR MSDKL38-PT-G is a locking knob handle plunger designed for precision indexing and positioning applications in industrial and mechanical assemblies. It features an M10x1.5 threaded body with a 20mm thread length and a stainless steel construction with a black finish. The Delrin knob provides a secure, ergonomic grip, and the built-in locking element holds the plunger in the retracted position until released. Initial end force is 0.22 pounds and final end force is 2.02 pounds, making it suited for light-duty to moderate-duty locking and positioning tasks.

This plunger is used in machine tool fixtures, workholding setups, jigs, enclosures, and mechanical positioning systems where a threaded, spring-loaded locking plunger is required. The M10x1.5 thread size fits standard metric tapped holes and is common in light industrial equipment, tooling plates, and fabricated assemblies. Installation is typically performed by machinists, tool and die makers, or maintenance technicians working on mechanical subassemblies.

Key Features

• Locking plunger type holds retracted position until manually released
• M10x1.5 thread with 20mm thread length for standard metric applications
• Stainless steel body with black finish for corrosion resistance and durability
• Delrin knob style provides ergonomic, non-slip grip
• Maximum plunger diameter of 0.236 inches (5.99mm) with 0.196 inches plunger projection
• Compact body length of 0.98 inches suits space-constrained installations

Compatibility

Designed as a direct-fit replacement or new-installation locking knob handle plunger for applications requiring an M10x1.5 threaded locking plunger with a Delrin knob and stainless steel body.

Installation Notes

Install into a properly tapped M10x1.5 through-hole or blind hole using a wrench on the 0.39-inch hex for torquing to the assembly specification. Ensure the mating bore diameter is appropriate for the 0.236-inch maximum plunger diameter before installation. Disengage any spring-loaded or pressurized mechanisms in the host assembly before servicing or replacing the plunger. Do not overtighten the threaded body, as this may damage the locking mechanism or the mating threads.
