Gibraltar SKNL-3-PT-G Knob Handle Plunger 3/8-16 Stainless

Product Description

The GIBRALTAR SKNL-3-PT-G is a non-locking knob handle plunger with a knurled knob grip, designed for indexing, positioning, and clamping applications in industrial and mechanical assemblies. It is threaded 3/8-16 with a 0.75 inch thread length and a maximum plunger diameter of 0.185 inches. The plunger delivers 1 pound initial end force building to 8 pounds final end force, making it suitable for light-duty hold and release cycles. The body is constructed from stainless steel for corrosion resistance in demanding environments. Machinists, tool and die technicians, and fixture builders typically install this component during machine assembly or fixture fabrication.

This plunger is used in jigs, fixtures, tooling plates, and mechanical panels where a manually operated spring plunger with a grippable knob head is required. The knurled knob style allows hand actuation without tools, well suited for frequent adjustment operations on production equipment, inspection fixtures, and positioning assemblies. Its compact body length of 0.94 inches fits into tight installation envelopes common in precision tooling setups.

Key Features

• 3/8-16 thread size with 0.75 inch thread length for secure engagement in standard tapped holes
• Non-locking plunger type with 1 pound initial to 8 pound final end force for repeatable indexing
• Stainless steel construction for corrosion resistance in wash-down or high-humidity environments
• Knurled knob head allows tool-free hand actuation during frequent adjustment cycles
• 0.185 inch maximum plunger diameter with a tight tolerance of plus 0.001 / minus 0.000 inches for precise fitment

Compatibility

Designed as a direct-fit replacement or OEM-style spring plunger for fixtures, jigs, and mechanical assemblies requiring a 3/8-16 threaded knob handle plunger with non-locking action.

Installation Notes

Installation is performed by machinists or mechanical assemblers threading the plunger into a tapped 3/8-16 hole to the specified engagement depth. Ensure the mating hole is clean and free of debris before installation. Apply thread-locking compound only if permanent retention is required, as the non-locking design is intended for serviceable assemblies. De-energize or lock out any associated equipment before installing or removing plungers in live machinery.
