It features a 1\/2-20 UNF thread form with a 3-inch length under the head and a 3\/4-inch hex drive. Constructed from Grade 18-8 stainless steel with no additional coating, this fastener delivers corrosion resistance suitable for environments where mild chemical exposure or moisture is a concern. The shank is partially threaded, allowing it to bear shear loads along the unthreaded portion while clamping through the threaded engagement zone. Machinists, maintenance technicians, pipefitters, and plumbers commonly use this type of fastener when stainless-grade hardware is specified by a design or code requirement.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in fabrication, equipment assembly, piping support, and mechanical system mounting where 1\/2-20 UNF thread engagement is required. The 18-8 stainless steel construction makes it a practical choice for indoor and outdoor installations exposed to water, mild chemicals, or temperature cycling. It is sold individually but subject to a minimum order quantity of 5 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF thread form for fine-thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial thread — allows shear load distribution along the unthreaded shank\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction for corrosion resistance without coating\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex drive compatible with standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no risk of coating delamination in high-cycle or high-temperature adjacent service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-20 UNF hex head cap screw for use in any application requiring a partially threaded, Grade 18-8 stainless steel fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, pipefitter, or technician following applicable fastener torque specifications for 1\/2-20 UNF stainless steel hardware as defined by the relevant design standard or equipment manufacturer. Use a properly sized 3\/4-inch hex wrench or socket to avoid rounding the drive surfaces. Exercise caution when torquing 18-8 stainless fasteners into stainless mating threads to prevent galling — apply an appropriate anti-seize compound as needed. De-energize or isolate any equipment before fastener removal or installation in live mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Drive Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 18-8 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5 pieces\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3SSC908F0300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720511783218,"sku":"3SSC908F0300","price":1399.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17635fb54548bb09af8e903ba4fe9d4a.jpg?v=1788565285","url":"https:\/\/voomisupply.com\/products\/value-collection-3ssc908f0300-hex-head-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
