Built to a 3\/8-16 UNC thread standard, it features a 2-inch length under the head and an overall length of 2-7\/8 inches. The winged head allows for firm finger-grip torque, making it well suited for assemblies that require frequent removal or adjustment. A zinc finish provides basic corrosion resistance. The shoulder design adds positional stability during installation. This fastener is sold individually and is used across a range of trade and industrial assembly scenarios.\u003c\/p\u003e\u003cp\u003eThis thumb screw is applicable in light mechanical assemblies, equipment panels, enclosures, and fixture mounting situations where repeated hand access is required. The 3\/8-16 UNC thread pattern makes it compatible with standard tapped holes in steel, aluminum, and other common structural materials. It is appropriate for both shop fabrication and field service work where a tool-free fastening solution is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWinged head design enables tool-free hand tightening and loosening\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC thread for compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003eWith-shoulder configuration provides alignment and load distribution\u003c\/li\u003e\n\u003cli\u003eZinc finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eIron construction — material grade 32510\u003c\/li\u003e\n\u003cli\u003e2-inch length under head with 2-7\/8-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 UNC winged thumb screw for use in applications requiring tool-free fastening in hand-accessible assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand; no tools are required for tightening under normal service loads. Ensure the mating tapped hole is clean and thread-compatible before installation. Do not use an impact driver or wrench on the winged head, as this may damage the head or strip the threads. Inspect threads for wear or deformation before reuse in critical assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: Winged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Type\u003c\/strong\u003e: With Shoulder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 32510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1-EFR-07-17-\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693289636146,"sku":"1-EFR-07-17-","price":17.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/267e648077d4b7165659d6b867af1c77.jpg?v=1788310200","url":"https:\/\/voomisupply.com\/products\/value-collection-1-efr-07-17-iron-thumb-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
