The GIBRALTAR G10-4300HK is a fluted knob designed for hand-adjustment applications in industrial, mechanical, and trade equipment assemblies. Featuring a 2.5-inch head diameter and a thru female insert configuration, this knob accepts a 3/8-16 threaded fastener and provides a secure, tool-free grip. The body is molded from nylon, offering lightweight construction and resistance to corrosion in environments where metal hardware may be unsuitable. HVAC technicians, electricians, plumbers, and equipment service professionals use knobs of this type to secure panels, guards, access doors, and adjustable components on service equipment and machinery.
This fluted knob is suited for light to medium-duty hand-tightening applications on equipment panels, enclosures, and fixtures that require frequent adjustment or removal without tools. The 3/8-16 female insert thread is a common standard fastener size found across a wide range of commercial and industrial equipment. The nylon construction makes it appropriate for both indoor and outdoor use where periodic exposure to moisture or mild chemicals may occur.
Designed as a standard replacement or new-installation fluted knob for equipment assemblies, panels, and fixtures using 3/8-16 threaded fasteners.
Installation requires no special tools. Thread the female insert onto a compatible 3/8-16 bolt or threaded rod and tighten by hand to the required holding force. De-energize or power down any equipment before servicing panels or guards where this knob is used as a fastening point. Do not overtighten, as nylon inserts can crack under excessive torque from tools.
