The GIBRALTAR KN6X-8X-S3----- is a self-fixing hole tapered knob made from polypropylene, designed for secure hand-tightening applications across a wide range of threaded hole sizes. The tapered knob design provides a comfortable grip surface while the self-fixing hole accepts multiple thread sizes without requiring a separate insert or fastener. At 2 inches overall length with a 1.38-inch head diameter and a 0.75-inch base diameter, this knob suits panel, fixture, and equipment assemblies where a clean black finish and lightweight construction are priorities. Technicians and assemblers in HVAC, electrical, and general equipment service use this type of knob for access panels, adjustment screws, and control fixtures.
This knob is suited for light-duty to medium-duty fastening tasks in both residential and commercial equipment. The self-fixing hole design accommodates unified and metric thread sizes including 3/8-16, 3/8-24, 1/2-13, 1/2-20, M10, and M12, making it a versatile choice when working across mixed-thread equipment or sourcing a single knob style for multiple applications. The 0.71-inch hole depth provides adequate thread engagement for standard fastening scenarios on panels, enclosures, and service access points.
Designed as a direct-fit self-fixing hole tapered knob for equipment, enclosures, and panels using 3/8-16, 3/8-24, 1/2-13, 1/2-20, M10, or M12 threaded fasteners.
Installation requires no special tools — press or thread the knob onto the appropriate fastener by hand. Confirm thread size and engagement depth before fully seating the knob to avoid cross-threading. Polypropylene knobs are not rated for high-torque applications; do not use an impact driver or wrench. Power down or de-energize any panel or enclosure before replacing or repositioning knobs on live equipment.
