Manufactured from Grade 6\/6 nylon with no finish coating, this fastener is suited for applications where corrosion resistance, electrical non-conductivity, or reduced weight is a priority over metal hardware. It meets ASTM D789-66 Type 1 GDE2 standards for nylon material quality. Installed with a standard hex wrench or socket, it provides a secure, rust-free mechanical connection in environments where metal fasteners would corrode, conduct electricity, or add unnecessary weight.\u003c\/p\u003e\u003cp\u003eNylon hex head cap screws in the 5\/16-18 UNC thread size are commonly used in HVAC, electrical, plumbing, and pool equipment assemblies where plastic or fiberglass panels, enclosures, and junction boxes require a non-metallic fastener. They are also used in light structural and equipment-mounting applications where chemical resistance or electrical isolation is required. Suitable for both indoor and outdoor installations where ambient conditions favor non-metallic hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 6\/6 nylon construction for corrosion resistance and electrical non-conductivity\u003c\/li\u003e\n\u003cli\u003eFully threaded along the entire shank length for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread standard for broad compatibility with inch-series hardware\u003c\/li\u003e\n\u003cli\u003e1 inch length under head provides consistent clamping depth\u003c\/li\u003e\n\u003cli\u003eUncoated finish maintains dimensional accuracy and chemical resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASTM D789-66 Type 1 GDE2 nylon material standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series nylon hex head cap screw for use in any application requiring a 5\/16-18 UNC fully threaded fastener in a non-metallic, uncoated nylon material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fastener should be installed by a qualified technician familiar with nylon hardware torque limitations. Nylon fasteners require lower torque than steel equivalents — avoid impact drivers and over-tightening, which can crack or strip the nylon threads. Power down or de-energize any equipment before fastener service in electrical or HVAC enclosures. Follow applicable NEC or equipment manufacturer guidelines for fastener material selection in electrical assemblies.\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: 1 inch\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: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 6\/6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM D789-66 Type 1 GDE2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ELECTRO HARDWARE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HHCS-516-1-N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51731271909682,"sku":"HHCS-516-1-N","price":96.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2cbc1c0b392eb062328fa8e4c05df372_366bb074-b537-4e16-b18e-18b9bf39f2f9.jpg?v=1788729094","url":"https:\/\/voomisupply.com\/products\/electro-hardware-hhcs-516-1-n-hex-head-cap-screw-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
