Sized at 1\/2-13 x 3-1\/2 inches and manufactured from Grade 316 stainless steel, this fastener delivers solid performance in wet, marine, chemical, or outdoor environments where inferior grades would corrode prematurely. The UNC thread form and partial threading configuration allow for controlled engagement depth in through-bolt and clearance-hole applications. Installed by millwrights, pipefitters, plumbers, and general tradespeople, this screw arrives uncoated to preserve its base metal properties for direct use or secondary finishing.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for residential and commercial applications where Grade 316 stainless steel is specified, including plumbing equipment mounting, pump and pipe support hardware, marine hardware, food-service equipment assembly, and chemical processing installations. The partial threading allows the unthreaded shank to pass cleanly through a clearance hole before engaging the threaded bore or nut, making it appropriate for lap joints and structural connections requiring a precise grip length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction provides superior corrosion resistance compared to Grade 304, including resistance to chlorides and acids\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread size with partial threading for versatile through-bolt and clearance-hole use\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch length under head accommodates thicker stack-ups and structural connections\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves dimensional tolerances and is compatible with secondary coatings or sealants\u003c\/li\u003e\n  \u003cli\u003eStandard hex head accepts common 3\/4 inch hex wrenches and sockets for straightforward installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application specifying a 1\/2-13 UNC fastener in Grade 316 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench to the specification required by the joint design or applicable code. Lubricate threads with an anti-galling compound appropriate for stainless steel to prevent thread seizure during installation, a common issue with austenitic stainless fasteners under high torque. Ensure mating threads or nuts are also Grade 316 or a compatible stainless alloy to avoid galvanic corrosion. Follow applicable mechanical and structural codes for fastener torque class and joint preload requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading Type\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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: 0.005 pounds\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: 204080B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713716617522,"sku":"204080B","price":5874.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81b0be87ea9b0b885c19e3584f39a1cf.jpg?v=1788494923","url":"https:\/\/voomisupply.com\/products\/value-collection-204080b-hex-cap-screw-1-2-13-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
