Gibraltar G10-3045-B Thermoplastic 3 Arm Knob 3/8-16

Product Description

The GIBRALTAR G10-3045-B is a three-arm hand knob machined from textured coated thermoplastic, designed for tool-free adjustment and clamping applications in industrial, mechanical, and light fabrication settings. The knob measures 2.5 inches in head diameter and 1.25 inches in height, with a 13/16-inch hub diameter. It uses a female insert style with a 3/8-16 threaded hole and a 0.5-inch hole depth. The textured black finish provides grip in oily or gloved-hand conditions. Technicians and assemblers working on fixtures, guards, panels, and equipment enclosures commonly specify this type of knob as a hand-operable fastening component.

This knob fits standard 3/8-16 threaded studs and bolts, making it a direct-fit adjustment knob for a broad range of industrial machinery, HVAC equipment access panels, electrical enclosures, and mechanical assemblies that require frequent hand-tightening and loosening without tooling. The female insert style accepts a protruding threaded stud. The black textured thermoplastic construction resists mild chemical exposure and provides low-friction operation across a wide range of ambient temperatures typical in shop and field environments.

Key Features

• Three-arm ergonomic profile for increased hand torque without tools
• Female insert threading accepts 3/8-16 threaded studs up to 0.5 inches deep
• 2.5-inch head diameter for comfortable grip by gloved hands
• Textured coated thermoplastic construction resists mild chemicals and wear
• Compact 1.25-inch height suits shallow clearance installations

Compatibility

Designed as an OEM-style or aftermarket hand knob for any application using a 3/8-16 threaded stud requiring tool-free hand adjustment.

Installation Notes

This knob is installed by threading the female insert onto an exposed 3/8-16 stud by hand. Ensure the stud protrusion does not exceed the 0.5-inch hole depth before installation to avoid bottoming out against the insert. No special tools are required for standard installation. When used on equipment under vibration, consider a secondary locking method such as a jam nut on the stud to prevent backing off.
