Gibraltar DKL50-PT-G Locking Knob Handle Plunger 1/2-13

Product Description

The GIBRALTAR DKL50-PT-G is a locking knob handle plunger designed for precision positioning and holding applications in industrial and mechanical assemblies. The plunger features a 1/2-13 thread size, a steel body with a black finish, and a Delrin knob head for a secure grip. It delivers an initial end force of 0.5 pounds and a final end force of 1.75 pounds, making it suitable for applications that require controlled resistance with a positive locking function. The maximum plunger diameter is 0.31 inches and the plunger projection measures 0.25 inches. Machinists, maintenance technicians, and mechanical assemblers typically install this type of component.

This locking plunger is suited for use in jigs, fixtures, machine tool setups, and industrial equipment where repeatable positioning or panel locking is required. The 1.25-inch body length and 1.0-inch length under the head and shoulder allow it to fit standard mounting configurations in both light-duty production tooling and general mechanical assemblies. The Delrin knob provides hand-tightening convenience without the need for additional tooling during normal operation.

Key Features

• Locking element engages to hold the plunger in a fixed, retracted position
• Delrin knob head allows tool-free hand operation
• Steel body with black finish for durability and corrosion resistance in shop environments
• 0.5 lb initial end force to 1.75 lb final end force for controlled spring resistance
• 1/2-13 thread size for compatibility with standard tapped mounting holes
• Compact 1.25-inch body length suits space-constrained installations

Compatibility

Designed as a direct-fit locking knob handle plunger for standard 1/2-13 threaded mounting holes in jigs, fixtures, and industrial mechanical assemblies.

Installation Notes

Installation is performed by threading the DKL50-PT-G into a pre-tapped 1/2-13 hole by hand or with a wrench applied to the hex flat. Ensure the mounting surface is clean and the thread engagement is sufficient for the applied load before use. Power down or de-energize any associated equipment before servicing components in the surrounding assembly. Do not exceed the rated end force values for the application.
