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

Product Description

The GIBRALTAR SKNL-3-G is a non-locking knob handle plunger with a knurled knob design, threaded body, and spring-loaded stainless steel plunger. It is used in industrial and mechanical assemblies where a hand-adjustable locating or indexing point is needed without a locking mechanism. The 3/8-16 thread size and 0.75-inch thread length allow direct installation into standard tapped holes. Initial end force is 1 pound, rising to a final end force of 8 pounds, making it suitable for light-duty positioning and retention applications. The stainless steel construction provides corrosion resistance in demanding environments.

This plunger is commonly used in machine tool fixtures, jigs, enclosures, and industrial equipment where repeatable manual indexing is required. The non-locking plunger type allows smooth engagement and release without additional tooling. Typical installation scenarios include panel assemblies, sliding mechanisms, and adjustable fixtures in light manufacturing or maintenance settings. The knurled knob allows hand operation without tools.

Key Features

• Non-locking plunger with 1 pound initial end force and 8 pound final end force

• Compact body length of 0.94 inches suits space-constrained assemblies

Compatibility

Designed as a direct-fit replacement or new installation for standard 3/8-16 tapped-hole applications requiring a non-locking spring plunger with knob handle.

Installation Notes

Installation is performed by threading the plunger body into a prepared 3/8-16 tapped hole by hand or with a wrench applied to the head. Ensure the mating bore or detent is aligned with the plunger projection before fully seating the thread. No special tools or codes are required for standard mechanical assembly, but installers should verify the tapped hole depth and thread condition before installation. Avoid overtightening, which can distort the body or affect plunger travel.
