Molded from phenolic material, this knob delivers a durable, gloss-finish grip surface that resists chemicals and wear under repeated use. The knob features a 1.5-inch head diameter and a 5\/16-18 threaded stem with 1 inch of thread engagement, making it well-suited for fastening to standard machine screws or threaded inserts. Maintenance technicians and assembly professionals install this type of hardware where tool-free adjustments are needed on panels, fixtures, jigs, guards, and control equipment.\u003c\/p\u003e\n\u003cp\u003eThis lobed knob is appropriate for use in light industrial and commercial equipment assemblies where frequent hand adjustment is required. The 4-lobe design provides multiple grip points for controlled torque without tools. The phenolic construction handles moderate temperature exposure and general shop environments. It is commonly found on machine guards, enclosure panels, positioning fixtures, and similar equipment requiring repetitive manual fastening. The 5\/16-18 thread size is a widely used standard that fits a broad range of bolts, studs, and threaded hardware found in fabrication and equipment maintenance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-point lobed profile for secure hand grip and tool-free adjustment\u003c\/li\u003e\n  \u003cli\u003e1.5-inch head diameter provides adequate leverage for manual tightening\u003c\/li\u003e\n  \u003cli\u003ePhenolic construction offers chemical resistance and durability in shop environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 stem thread is a standard size compatible with common machine hardware\u003c\/li\u003e\n  \u003cli\u003e1 inch of thread length provides solid engagement depth\u003c\/li\u003e\n  \u003cli\u003eGloss black finish for visibility and a clean, finished appearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard lobed knob replacement or new-installation component for 5\/16-18 threaded studs, bolts, or inserts commonly found in light industrial machinery, equipment panels, jigs, and fixtures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis knob is installed by hand onto a 5\/16-18 threaded fastener or stud.
