The 1\/4-20 UNC thread and 15\/16 inch overall length make this a compact, corrosion-resistant fastener suited for panels, enclosures, covers, and assemblies that require frequent removal or adjustment. The knurled head provides secure finger grip without additional hardware. At 303 stainless steel grade, this screw offers good corrosion resistance and machinability, meeting QQ-S-763 material standards. It is supplied uncoated with no shoulder.\u003c\/p\u003e\n\u003cp\u003eThis thumb screw is well suited for light industrial, electrical, HVAC, and mechanical assembly applications where quick-disconnect fastening is needed. It is commonly used in control panels, access covers, junction boxes, and equipment enclosures. The 1\/4-20 UNC thread is one of the most widely used fastener thread standards in inch-system mechanical assembly, making this screw broadly compatible across trade and industrial applications. Installation requires no special tools, making it appropriate for field service and maintenance use by electricians, HVAC technicians, and mechanical assemblers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e303 stainless steel construction meeting QQ-S-763 standard for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eKnurled head for tool-free hand tightening and removal\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread standard, widely compatible with inch-system hardware\u003c\/li\u003e\n  \u003cli\u003e11\/16 inch thread length provides reliable thread engagement\u003c\/li\u003e\n  \u003cli\u003eNo shoulder design for flush or direct panel mounting\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy and conductivity where needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC inch-system thumb screw for use in panel, enclosure, and equipment fastening applications requiring hand-operated removal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by hand into a pre-tapped 1\/4-20 UNC threaded hole or with a matching 1\/4-20 nut.
