The rosette head profile provides a larger gripping surface compared to standard knurled thumb screws, allowing adequate torque by hand without tools. The screw measures 1.5 inches in overall length with a 3\/8-inch cap screw size and is molded from black plastic, making it well suited for applications where corrosion resistance and electrical non-conductivity are priorities. Sold in packages of 100, this fastener fits production, MRO, and field service purchasing needs.\u003c\/p\u003e\u003cp\u003eThis thumb screw is used in light industrial, electronic, and mechanical assembly applications where panels, covers, or access doors require frequent removal. The rosette head design is common in rack-mounted equipment, instrument enclosures, and machine guards. Its plastic construction makes it appropriate in environments where metal fasteners would cause galvanic corrosion concerns or where non-conductive hardware is required. Installation requires no special tools, making it practical for field technicians, assemblers, and maintenance personnel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRosette head profile provides increased grip surface for hand tightening without tools\u003c\/li\u003e\n\u003cli\u003eFull plastic construction resists corrosion and provides electrical non-conductivity\u003c\/li\u003e\n\u003cli\u003e1.5-inch overall length suits standard panel and cover fastening applications\u003c\/li\u003e\n\u003cli\u003eBlack head color for a consistent, clean appearance in finished assemblies\u003c\/li\u003e\n\u003cli\u003eShoulder diameter of 45\/64 inch helps with panel alignment during installation\u003c\/li\u003e\n\u003cli\u003eSold in a 100-piece package, suitable for production runs and MRO stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose rosette head thumb screw for light-duty fastening applications using 3\/8-inch cap screw sizing in inch-measured assemblies with metric thread standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand without tools in most applications. Verify thread engagement is complete before applying load to the fastener. As with all plastic fasteners, avoid overtightening, which can strip threads or crack the head.
