It features a lobed aluminum head for hand-tightening grip, a black oxide steel body for corrosion resistance, and a dog point tip for positive location and alignment in mating holes. The 5\/8-11 UNC thread and with-shoulder construction give it the load capacity and rigidity expected in demanding trade and manufacturing environments. At 4.5 inches overall length and 0.39 pounds, it is built for repetitive use in high-cycle applications.\u003c\/p\u003e\n\u003cp\u003eThis thumb screw is suited for use in machine shops, fabrication environments, and industrial assembly stations where hand-operated clamping or positioning hardware is required. The dog point tip seats into locating holes or slots to prevent lateral movement during tightening. The lobed head allows significant hand torque without tools, making it practical for setups requiring frequent adjustment. It is sized for applications that demand a large-diameter head for grip and a substantial thread engagement length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread for high load capacity and broad tooling compatibility\u003c\/li\u003e\n  \u003cli\u003eLobed aluminum head, 2.5 inches in diameter and 1.5 inches in height, for firm hand grip\u003c\/li\u003e\n  \u003cli\u003eDog point tip, 0.4375 inches in diameter and 0.3125 inches in length, for positive locating in mating holes\u003c\/li\u003e\n  \u003cli\u003eWith-shoulder construction for controlled clamping depth and lateral stability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced surface glare\u003c\/li\u003e\n  \u003cli\u003e4.5 inches overall length suits deep-reach clamping and fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC 5\/8-11 threaded thumb screw for use in industrial fixtures, workholding systems, and machine tool assemblies requiring lobed-head hand hardware with a dog point tip and shoulder configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, toolmakers, or maintenance technicians in fabrication and industrial settings. Verify that the mating thread and dog point locating hole match the 5\/8-11 UNC thread standard and 0.4375-inch tip diameter before installation. Do not use power tools to drive or remove this thumb screw, as the lobed head is intended for hand operation. Ensure mating threads are clean and free of debris to maintain proper engagement and torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Lobed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Type\u003c\/strong\u003e: With Shoulder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Dog Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 90424G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51709026861362,"sku":"90424G","price":88.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c616f5c5ae30d62e9e87d7c8a9e5922_85d0c1d9-ee93-4035-8afb-c6351040d954.jpg?v=1788450186","url":"https:\/\/voomisupply.com\/products\/gibraltar-90424g-steel-thumb-screw-5-8-11-lobed-head","provider":"Voomi Supply","version":"1.0","type":"link"}
