The screw features a 2-inch head diameter and a knurled or contoured grip profile that allows operators to apply controlled torque by hand without tooling. With an adjustable torque range of 3 to 12 inch-pounds and a stem diameter of 0.734 inches, this fastener suits applications where repeatable hand-tightened clamping or adjustment is required. The all-aluminum construction keeps the component lightweight while maintaining the dimensional precision required for production and assembly environments.\u003c\/p\u003e\n\u003cp\u003eThe TH104 is suited for use in industrial machinery, fixture plates, jigs, and mechanical positioning systems where frequent manual adjustment is part of normal operation. Its aluminum material makes it a practical choice in environments where weight reduction, corrosion resistance, or non-magnetic properties are priorities. Maintenance technicians, machine builders, and fixture designers are the primary installers of this type of component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum construction for lightweight and corrosion-resistant performance\u003c\/li\u003e\n  \u003cli\u003e2-inch head diameter for comfortable hand grip and torque application\u003c\/li\u003e\n  \u003cli\u003eAdjustable torque range of 3 to 12 inch-pounds for controlled clamping\u003c\/li\u003e\n  \u003cli\u003eStem diameter of 0.734 inches for precise thread engagement\u003c\/li\u003e\n  \u003cli\u003eStem length and tip length each measure 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001 quality management standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit thumb screw for mechanical assemblies, fixture systems, and positioning equipment requiring a 2-inch head diameter fastener with a 0.734-inch stem diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand without specialized tooling. Ensure the mating threaded hole is clean and free of debris before threading the stem in. Do not exceed the rated torque range by using mechanical tools, as this may damage the aluminum threads or the mating component. Confirm proper thread engagement before applying load to the assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.734 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Torque Range\u003c\/strong\u003e: 3 to 12 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161516\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: VLIER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TH104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52109393264946,"sku":"TH104","price":146.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f049e7fed251b5881ea29f7eef42725.jpg?v=1790075579","url":"https:\/\/voomisupply.com\/products\/vlier-th104-aluminum-thumb-screw-2-inch-head","provider":"Voomi Supply","version":"1.0","type":"link"}
