Gibraltar G10-2980-P Lobed Knob 2.25 in 5-point 3/8-16

Product Description

The GIBRALTAR G10-2980-P is a 5-point lobed knob constructed from thermoplastic elastomer (TPE), designed for tool-free manual adjustment and clamping applications in industrial, mechanical, and equipment assembly settings. The knob features a 2.25-inch head diameter with a 3/8-16 threaded stem and 1-inch thread length, providing a secure grip surface for operators in environments where frequent hand-tightening is required. The TPE material delivers resistance to oils, chemicals, and moderate temperature variation while maintaining a firm, comfortable grip. Licensed tradespeople and equipment assemblers install this knob as a functional hardware component on machinery, fixtures, and control panels.

This lobed knob is suited for use on industrial machinery, jigs, fixtures, workholding equipment, and mechanical assemblies requiring repeated hand adjustment without tools. The 5-lobe profile distributes grip force evenly, reducing hand fatigue during frequent adjustment cycles. The 3/8-16 thread is a standard UNC size, making this knob compatible with a wide range of threaded studs, bolts, and threaded inserts commonly found in fabrication and manufacturing environments.

Key Features

• 5-point lobed profile for even grip force distribution and reduced hand fatigue
• 2.25-inch head diameter for confident manual torque without tools
• Thermoplastic elastomer construction resists oils, chemicals, and moderate temperatures
• 3/8-16 UNC threaded stem with 1-inch thread length fits standard hardware
• Hub diameter of 0.84 inches and overall height of 0.78 inches for compact fitment

Compatibility

Designed for use with standard 3/8-16 UNC threaded studs, bolts, and threaded inserts commonly found on industrial machinery, fixtures, and mechanical assemblies.

Installation Notes

Installation requires no special tools — hand-thread the knob onto a compatible 3/8-16 stud or bolt until snug. Verify that thread engagement meets at least the minimum depth required for the application load before putting the assembly into service. Do not use impact tools or wrenches on this knob, as excess torque may damage the TPE body or the threaded insert. Inspect threads periodically for wear in high-cycle applications.
