Gibraltar SKS-028-G Knurled Knob Threaded Stem Steel

Product Description

The GIBRALTAR SKS-028-G is a knurled knob with a threaded stem, designed for secure manual adjustment and fastening in industrial, mechanical, and trade applications. The knob features a 2.5-inch head diameter that provides a solid gripping surface for hand-tightening without tools. Constructed from steel, it delivers the durability needed in demanding service environments. This type of hardware is commonly specified by maintenance technicians, contractors, and equipment installers who require reliable, tool-free adjustability on panels, fixtures, jigs, and assemblies.

The SKS-028-G is suited for use in a wide range of industrial and trade settings where a threaded knob is needed for panel retention, cover fastening, or adjustable clamping. The 1/2-13 stem thread size is a standard unified coarse thread, making it compatible with commonly tapped holes in steel and aluminum fixtures. It is appropriate for light to moderate clamping loads in both stationary and repositionable assemblies across HVAC equipment panels, electrical enclosures, and mechanical fixtures.

Key Features

• 2.5-inch head diameter for comfortable hand grip and torque without tools

Compatibility

Designed as an OEM-style replacement or direct-fit hardware component for assemblies requiring a 1/2-13 threaded knurled knob with a 2.5-inch head diameter in steel.

Installation Notes

Installation is typically performed by maintenance technicians or equipment assemblers using hand pressure or light tool assistance to start the thread. Ensure the mating tapped hole is clean and free of debris before threading the stem. Do not overtighten, as knurled knobs are designed for hand-adjustment service loads. Confirm thread engagement is sufficient to prevent loosening under vibration in the intended application.
