The GIBRALTAR 5B40F206A8Z001G is a 5-point lobed knob molded from thermoplastic elastomer (TPE) in black finish. This knob provides a comfortable, no-slip grip for hand-tightened fastening applications. The lobed profile distributes finger pressure across five points, making it well-suited for panel covers, access doors, enclosure latches, and equipment adjustment hardware found in HVAC, electrical, and general mechanical installations. The TPE construction offers flexibility and resistance to oils, solvents, and temperature variation typical in trade environments. With a head diameter of 1.52 inches and an overall height of 1.09 inches, it is compact enough for tight-clearance panel work.
This lobed knob is used wherever a threaded fastener requires frequent hand adjustment without tools. Common applications include access panels on air handlers and fan coil units, electrical enclosure covers, control cabinet hardware, and light equipment assemblies. It accepts a 5/16-18 threaded stem, a common thread specification across sheet metal, extruded aluminum, and fabricated steel assemblies in residential and light commercial trade work.
Designed as a hand-tightening knob for 5/16-18 threaded fastener applications in trade equipment, enclosures, and panel assemblies. Verify thread engagement depth and stem length requirements before installation.
Installation is performed by hand or with light tool assist on a 5/16-18 threaded stud or insert. De-energize or isolate any panel or enclosure before servicing fasteners on live electrical or HVAC equipment. Do not over-torque; TPE knobs are designed for hand-tightened service loads only. Confirm thread compatibility and insert depth before final assembly.
