The screw features a 3\/8-16 UNC thread and a length under head of 3 inches, making it suitable for securing panels, covers, guards, and assemblies that require frequent removal or adjustment. The winged head provides adequate grip surface for finger-tightening, while the shouldered shank adds a locating function to help align mating components. This fastener is installed by maintenance technicians, millwrights, and equipment assemblers across light industrial, mechanical, and trade service environments.\u003c\/p\u003e\u003cp\u003eThis thumb screw is commonly used in applications where repeated hand access is needed, such as removable access panels, equipment enclosures, jigs, fixtures, and light-duty clamping assemblies. The shoulder design is useful when a controlled fit or alignment feature is required between mating parts. The zinc finish provides a basic level of corrosion resistance suitable for dry or lightly protected indoor environments. The 3\/8-16 UNC thread is a widely used coarse-thread standard, compatible with standard nuts, inserts, and tapped holes in that size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC coarse thread for compatibility with standard hardware\u003c\/li\u003e\n\u003cli\u003eWinged head allows hand-tightening without tools\u003c\/li\u003e\n\u003cli\u003eWith-shoulder design aids part alignment and controlled seating\u003c\/li\u003e\n\u003cli\u003eIron construction with zinc finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3 inch length under head suits moderate-depth panel and enclosure fastening\u003c\/li\u003e\n\u003cli\u003e1-11\/16 inch head diameter provides adequate grip surface for finger operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 UNC winged thumb screw suitable for use in any application requiring a hand-tightened fastener with a shoulder and winged head in that thread size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no tools under normal hand-tightening conditions. Ensure the mating tapped hole or nut matches the 3\/8-16 UNC thread specification before installation. Do not use power tools or wrenches on the winged head, as this may damage the head geometry or over-torque the fastener. Inspect threads and the shoulder fit for proper engagement before applying load to the assembly.\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-11\/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-EFT-10-17-\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700148633906,"sku":"1-EFT-10-17-","price":20.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e25cabb07041aa9dde026e8fdf8846d.jpg?v=1788386749","url":"https:\/\/voomisupply.com\/products\/value-collection-1-eft-10-17-iron-thumb-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
