Manufactured from 18-8 stainless steel and passivated for enhanced corrosion resistance, this bolt features a silicone O-ring under the head that compresses on installation to form a tight seal against fluid or gas migration. The 5\/16-18 UNC thread and 1-1\/2 inch length under head make it a practical fastener for a wide range of mechanical, plumbing, and equipment assembly tasks. Each package contains 5 bolts. Installation requires a standard hex wrench or socket driver appropriate for the bolt head size.\u003c\/p\u003e\n\u003cp\u003eThis self sealing hex bolt is suited for use in HVAC equipment panels, pump housings, enclosures, and other assemblies where preventing moisture or fluid ingress at the fastener point is important. The passivated 18-8 stainless steel construction resists rust and chemical exposure, making it appropriate for both indoor and outdoor installations, as well as wet or corrosive environments common in plumbing and pool service applications. Typically installed by HVAC technicians, plumbers, and mechanical contractors during equipment assembly or repair.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone O-ring under head creates a compression seal to prevent fluid or gas leakage at the fastener point\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion and rust resistance\u003c\/li\u003e\n  \u003cli\u003ePassivated finish enhances surface corrosion resistance beyond standard stainless steel\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 5 bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use fastener for any application requiring a 5\/16-18 UNC self sealing hex bolt with an 18-8 stainless steel body and silicone O-ring seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a properly sized hex socket or open-end wrench.
