Gibraltar G10-3041-E 3 Arm Knob 2 in Head 5/16-18 Stem Black

Product Description

The GIBRALTAR G10-3041-E is a textured coated thermoplastic three-arm knob designed for hand-adjustment applications on equipment panels, enclosures, jigs, and fixtures. The knob features a 2-inch head diameter, stands 1 inch high, and includes a 3/4-inch long threaded stem with a 5/16-18 thread form. The black textured finish provides a firm, no-slip grip without requiring tools. Threaded stem style allows direct installation onto compatible threaded studs or bolts. Suitable for light-duty mechanical and electrical enclosure use where frequent manual adjustment is required.

This knob is commonly used in industrial, HVAC, electrical, and equipment-panel applications where a hand-tightenable fastener is needed. The 3/4-inch hub diameter and threaded stem style make it well suited for panel mounting on control boxes, access doors, equipment guards, and similar assemblies. Installers in electrical, HVAC, and general mechanical trades use this style of knob as a replacement or upgrade for slotted or hex fasteners in frequently accessed locations.

Key Features

• 2-inch head diameter for a secure, comfortable hand grip
• 5/16-18 threaded stem for broad fastener compatibility
• 3/4-inch long thread provides sufficient engagement depth for panel applications
• Textured coated thermoplastic construction resists oils and common shop contaminants
• Three-arm design distributes hand torque evenly for consistent clamping force
• Black finish blends with standard equipment panel aesthetics

Compatibility

Designed as a general-purpose hand-knob fastener for equipment panels, enclosures, and fixtures that use a 5/16-18 threaded stud or bolt.

Installation Notes

Installation requires no tools under normal use — thread the knob onto a 5/16-18 stud or bolt by hand and tighten to the desired clamping force. Ensure the mating thread is clean and free of debris before installation. For panel or enclosure applications, power down or de-energize the assembly before accessing internal components. Do not exceed the hand-tightening torque appropriate for thermoplastic fasteners, as over-torquing can crack the hub.
