This is the M10x85mm bolt that threads into the upper hole on your post mount. It's genuine zinc-plated Honda hardware, and it's what secures the top of the post mount to the engine. Whether you're fitting Hasport mounts, replacing tired factory ones, or building a swap, this is the correct bolt rather than whatever came closest in your hardware bin.\u003c\/p\u003e\n\n\u003ch4\u003eDon't Reuse Your Old Mount Bolts\u003c\/h4\u003e\n\n\u003cp\u003eWorth taking seriously, because this is the part people skip and it matters.\u003c\/p\u003e\n\n\u003cp\u003eEngine mount bolts stretch and fatigue over time from constant vibration and engine movement. Yours have been torqued down for years, possibly decades depending on the car. Threads deform, and the bolt loses clamping force even though it looks fine.\u003c\/p\u003e\n\n\u003cp\u003eWhat that means practically is that an old bolt won't torque to spec properly, and a mount that isn't clamped correctly can work loose. A loose engine mount lets the motor move considerably more than it should, which shows up as vibration and clunking over bumps. In the worst case the engine shifts enough to break exhaust mounts, damage axles, or contact the firewall.\u003c\/p\u003e\n\n\u003cp\u003eYou're already spending money on mounts. Fresh hardware is the cheapest part of the job and the one that determines whether the rest of it stays tight.\u003c\/p\u003e\n\n\u003ch4\u003eM10 x 85mm, Use The Right Length\u003c\/h4\u003e\n\n\u003cp\u003eThis bolt is \u003cstrong\u003eM10 x 85mm\u003c\/strong\u003e, sized specifically for the upper post mount hole.\u003c\/p\u003e\n\n\u003cp\u003eLength matters more than people assume. Too short and you don't get enough thread engagement to clamp properly. Too long and it bottoms out before the mount is actually tight, which feels torqued but isn't. Either way you've got a mount that isn't secured the way it needs to be.\u003c\/p\u003e\n\n\u003cp\u003eWorth noting the upper and lower post mount bolts are different lengths, so don't assume one substitutes for the other.\u003c\/p\u003e\n\n\u003ch4\u003eGenuine Honda Hardware\u003c\/h4\u003e\n\n\u003cp\u003eThis is the factory part, not a generic bolt from a hardware store.\u003c\/p\u003e\n\n\u003cp\u003eIt's zinc plated to resist corrosion in an engine bay that sees heat and moisture constantly, the threads are cut to spec, and the bolt is heat treated to the correct hardness. Hardware store bolts vary enormously in quality, and a soft one will strip or stretch when you torque it, which is exactly the failure you're trying to avoid.\u003c\/p\u003e\n\n\u003cp\u003eOn a fastener holding your engine to the car, saving a few dollars isn't a trade worth making.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e2016-2026 Honda Civic LX and Sport (2.0 NA)\u003cbr\u003e2017-2021 Honda Civic Type R (FK8)\u003cbr\u003e2023-2026 Honda Civic Type R (FL5)\u003cbr\u003e2018-2022 Honda Accord 2.0T\u003cbr\u003e2002-2014 Honda CR-V\u003cbr\u003e2003-2011 Honda Element\u003cbr\u003e2023-2026 Honda HR-V\u003cbr\u003e2007-2012 Acura RDX\u003cbr\u003e2019-2025 Acura RDX\u003cbr\u003e2021-2025 Acura TLX\u003cbr\u003e2024-2026 Acura Integra Type S\u003c\/p\u003e\n\n\u003cp\u003eGenuine Honda part number 90008-PPA-000.\u003c\/p\u003e\n\n\u003ch4\u003eWho Should Grab One\u003c\/h4\u003e\n\n\u003cp\u003eThis is for anyone installing new engine mounts, replacing worn factory ones, or building a swap where the post mount is going in fresh.
