Manufactured from stainless steel, this fastener resists corrosion in wet, outdoor, and chemically exposed environments. The screw features a 5\/16-18 UNC thread size and measures 3-3\/4 inches under the head. Partial threading along the shank allows for a strong grip in thicker material stacks and helps prevent thread stripping in high-load applications. Suitable for use by mechanical contractors, HVAC installers, plumbers, and electricians where a reliable, corrosion-resistant fastener is required.\u003c\/p\u003e\u003cp\u003eThis cap screw is commonly used in light structural connections, equipment mounting, pipe hangers, electrical enclosure assembly, and HVAC unit installation. The partially threaded design suits applications where a clamp load between two surfaces is needed without threading through the entire grip length. It is appropriate for both indoor and outdoor installations where stainless steel's durability provides long-term performance in demanding trade environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread for broad tool and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e3-3\/4 inch length under head accommodates thicker material stacks\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides positive clamping between mating surfaces\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion in wet and outdoor environments\u003c\/li\u003e\n\u003cli\u003eHex head drive accepts standard hex wrenches and socket sets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC hex head cap screw suitable for use wherever a 5\/16-18 stainless steel partially threaded fastener is specified in mechanical, HVAC, plumbing, or electrical installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a standard hex wrench or socket set sized for a 5\/16-inch hex head cap screw. De-energize equipment and relieve system pressure before fastening components in live mechanical or electrical systems. Follow applicable codes including NEC, IPC, or IFGC as relevant to the assembly being secured. Avoid over-torquing stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound on the threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\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\u003eWeight\u003c\/strong\u003e: 0.25 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: R57001213\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701125087538,"sku":"R57001213","price":4855.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b22baed0b5b4dc6c734b1aaf2106142.jpg?v=1788398516","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001213-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
