Gibraltar G10-4300FK Fluted Knob 2.5 in Nylon 5/16-18

Product Description

The GIBRALTAR G10-4300FK is a fluted knob with a 2.5-inch head diameter, designed for hand-tightening applications where a secure, tool-free grip is needed. The knob features a thru female insert configuration, allowing a threaded rod or bolt to pass completely through. Constructed from nylon, it offers resistance to corrosion and is lightweight for repeated manual adjustment. This type of knob is commonly specified in industrial, mechanical, and trade settings where operators need to frequently loosen or tighten fastened assemblies without reaching for tools.

The G10-4300FK is suited for use in panel assemblies, equipment enclosures, jigs, fixtures, and machinery requiring manual adjustment points. The 5/16-18 thread size covers a wide range of standard fastener applications. It is appropriate for both light industrial and commercial installations where nylon hardware is preferred over metal to avoid surface marring or galvanic corrosion concerns.

Key Features

• 2.5-inch head diameter for a comfortable, positive grip during hand-tightening
• Fluted outer profile increases torque transfer without tools
• Thru female insert design allows full thread engagement or rod pass-through
• Nylon construction resists corrosion and is non-marring on mating surfaces
• 5/16-18 UNC thread size fits standard fastener hardware

Compatibility

Designed as an OEM-style replacement or standard-fit component for equipment and assemblies requiring a 5/16-18 thru female insert fluted knob.

Installation Notes

Install by threading onto a 5/16-18 bolt or rod by hand. Ensure the mating thread is clean and free of debris before engagement. No special tools are required for installation, but do not exceed the knob material torque limits by using mechanical aids. Verify the thread direction and depth match the application before final assembly.
