Gibraltar WSS-029-G Knurled Knob Threaded Stem 2.5 in

Product Description

The GIBRALTAR WSS-029-G is a knurled knob with a threaded stem, constructed from stainless steel for corrosion resistance in demanding service environments. The knob features a 2.5-inch head diameter, providing a secure, tool-free grip for manual adjustment, clamping, or fastening tasks. The stem is threaded to a 1/2-13 UNC specification, making it compatible with standard threaded inserts and fixtures. At 1.35 pounds, this is a solid, durable hardware component suited for use by HVAC technicians, plumbers, electricians, and general mechanical trades where hand-adjustable fasteners are required.

This knurled knob is used wherever a hand-tightened, removable fastening solution is needed. Typical applications include equipment panels, access doors, pipe brackets, electrical enclosures, and mechanical assemblies that require frequent removal or adjustment without tools. The stainless steel construction makes it appropriate for both indoor and outdoor installations, including damp or corrosive environments common in mechanical rooms, rooftop equipment, and poolside service settings.
