Lobed knobs provide manual grip control for adjusting, clamping, or securing threaded fasteners without tools. This knob accepts a 3\/8-16 threaded stem with 1 inch of thread engagement. The TPE construction offers a firm yet comfortable grip surface, making it well suited for frequent hand adjustments in light industrial, HVAC panel, or equipment enclosure applications. With a head diameter of 1.99 inches and an overall height of 0.86 inches, this is a compact, low-profile knob suitable for space-limited mounting locations.\u003c\/p\u003e\n\u003cp\u003eThis lobed knob is used wherever a tool-free hand adjustment point is needed on threaded fasteners. Common applications include HVAC equipment access panels, control enclosures, light industrial machinery, and trade service equipment where technicians need to make repeated manual adjustments. The 3\/8-16 thread pattern is a widely used coarse thread standard across equipment platforms, and the 1-inch thread length supports standard fastening depth in most panel and bracket installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-point lobed profile for positive hand grip during tool-free adjustments\u003c\/li\u003e\n  \u003cli\u003eThermoplastic elastomer construction for firm grip and durability\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 threaded stem with 1 inch of thread length\u003c\/li\u003e\n  \u003cli\u003eHead diameter of 1.99 inches for comfortable palm engagement\u003c\/li\u003e\n  \u003cli\u003eLow-profile design at 0.86 inches overall height\u003c\/li\u003e\n  \u003cli\u003eBlack finish, suitable for panel and enclosure applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or original-install lobed knob for 3\/8-16 threaded fastener applications in light industrial, HVAC, and equipment enclosure settings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — thread the knob onto any compatible 3\/8-16 stud or bolt by hand. Ensure the mating thread is clean and free of debris before installation. Do not exceed hand-tightening torque, as over-torquing a TPE knob body may cause cracking or thread damage. Confirm power is removed from any electrical enclosure before accessing panel hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Type\u003c\/strong\u003e: Lobed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Thermoplastic Elastomer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.99 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 0.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 0.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 0.86 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162801\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5A03B941A8Z001G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51720707440946,"sku":"5A03B941A8Z001G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b15861d8da34f75d9aa5db55849acdc5.jpg?v=1788568013","url":"https:\/\/voomisupply.com\/products\/gibraltar-5a03b941a8z001g-lobed-knob-4-point-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
