The knurled head allows hand-tightening without tools, making it a practical fastener for panels, enclosures, access covers, and equipment assemblies that require frequent removal or adjustment. The uncoated bright finish is standard for brass hardware of this grade and provides a clean appearance with natural corrosion resistance. Overall height is 0.406 inches (13\/32 inches), head diameter is 0.625 inches (5\/8 inches), and base diameter is 0.531 inches. This nut ships individually and has a minimum order quantity of 2 units.\u003c\/p\u003e\u003cp\u003eThis thumb nut is suited for light industrial, electrical, HVAC, and mechanical assembly applications where a tool-free fastening point is needed. The 5\/16-18 UNC thread is a common coarse-thread standard, compatible with standard 5\/16-18 threaded studs and bolts found in panel assemblies, control enclosures, junction boxes, and equipment covers. The brass construction makes it appropriate for applications where ferrous hardware is undesirable due to corrosion or conductivity concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade B633 brass construction — naturally corrosion resistant, non-ferrous\u003c\/li\u003e\n\u003cli\u003eRound knurled head for secure hand-tightening without tools\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC coarse thread — widely compatible with standard threaded studs and bolts\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish — no coating to chip or flake in service\u003c\/li\u003e\n\u003cli\u003eCompact profile: 0.406 inches overall height, 0.625 inches head diameter\u003c\/li\u003e\n\u003cli\u003eMeets QQ-B-626B Comp 22 standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 5\/16-18 UNC threaded studs and bolts in panel, enclosure, and equipment assembly applications where a hand-operable fastener is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread engagement should be verified before tightening to prevent cross-threading. Hand-tighten only — thumb nuts are not designed for wrench torque and may deform if over-tightened with tools. Inspect mating threads for cleanliness and damage before installation.
