Hey guys, if you’ve ever been to a motorcycle or small aircraft crash scene (don’t worry, I’ve seen my fair share of these through the work I do as a fairing bolts supplier), one of the most common questions I get from fellow gearheads, mechanics, and even crash investigators is this: “Can I just reuse those fairing bolts after a crash?” I get it—you hate spending extra cash on new parts, especially when the old ones look fine at first glance. But before you grab that socket wrench and start tightening, let’s break this down like I’m chatting with a buddy over a cold beer. No fancy jargon, just real talk about what actually happens to those bolts when things go sideways. Fairing Bolts
First, let’s make sure we’re all on the same page about what fairing bolts do. They’re not just tiny pretty fasteners holding your bike’s plastic fairings or a small plane’s aerodynamic panels on—they’re the unsung heroes that keep those panels from flapping loose at 100 mph, right? When a crash hits, whether you lowside your ninja bike or bump a plane’s wing during a landing mishap, those bolts take the brunt of the force. I’ve had a guy come to me last month saying his “crash was just a tap on the guardrail, the fairing only scratched a little” and he wanted to reuse the bolts. Spoiler alert: that “little tap” might’ve done way more damage than he saw.
Let’s start with the basics: what actually causes bolts to fail in a crash? It’s not just that they bend, even though that’s the obvious one. When a crash happens, two main forces act on fairing bolts—shear and tension. Shear is when two parts slide past each other in opposite directions, like when your fairing slams into a guardrail and the bolt has to hold the panel to the frame. Tension is pulling, like if your bike flips and the panel gets stretched away from the frame. Both forces put stress on the bolt, and even if the bolt looks straight and unmarked, that stress can leave micro-cracks you can’t see with the naked eye. I’m not talking about a tiny scratch here—we’re talking about cracks smaller than a human hair that will grow and break the bolt the next time you’re going for a ride.
Wait, but what about grade 8 bolts? Or titanium ones? I sell both, so I get this question a lot. Titanium is strong, sure, but it’s not invincible. A 2021 study from the American Society for Testing and Materials (ASTM) on fastener performance in impact loads found that even high-grade titanium bolts can develop residual stress after a crash that leads to what’s called “delayed fracture.” That means the bolt might look fine a week later, then snap while you’re cruising down the highway. Yeah, that’s as scary as it sounds. Grade 8 bolts are tougher too, but the same thing applies—impact doesn’t just leave marks on the surface, it messes with the metal’s internal structure.
Another big thing: thread damage. Fairing bolts thread into either metal inserts in the frame or plastic threaded holes in the fairing, right? When you crash, the bolt can twist in the hole, stripping or bending the threads. Even if the threads look okay, when you loosen the bolt to take the fairing off, you might notice it feels “grainy” or like it’s catching a little. That’s not normal, and it means the threads are worn down from the impact. If you reuse that bolt, it might not tighten properly, and the next time you hit a bump or a little crash, it’ll pull right out. I had a customer a couple years ago who reused bolts after a small crash, and his fairing flew off at 70 mph on the freeway. He totaled his bike, and that could’ve been way worse.
But wait—are there any exceptions? I don’t want to scare everyone into buying new bolts every time they drop their bike, because that’s expensive. Let’s be real, most of us aren’t racing and crashing every weekend. If it’s a super minor incident—like, say, you leaned your bike against a wall and it only tipped a little, no fairing damage at all—should you be okay? Maybe, but even then, I’d do a quick check. Run your finger over the bolt’s shaft to feel for any bends or scratches, inspect the threads with a magnifying glass if you have one, and tighten it to the manufacturer’s torque spec. If it feels loose, catches, or bends when you tighten it, toss it. No exceptions. But if it’s a real crash—even a low-speed one where the fairing is scraped up, the bolt took a hit—don’t risk it.
Let me also talk about what I tell my own team when we get returns of bolts from crashed bikes. We sort them, and I see firsthand how many bolts that look totally fine on the outside are actually broken inside. Last quarter, we did a test where we took 50 bolts from bikes that had been in crashes, all with no visible damage, and put them under a load test. 12 of them snapped before reaching their rated torque. 12 out of 50! That’s a 24% failure rate, and these were bolts that looked brand new. Can you imagine how scary that would be if one of those snapped while you were riding?
Also, let’s not forget about safety regulations. If you’re using your bike or plane for commercial use—like courier work or flight training—you can’t reuse bolts after a crash. It’s against safety standards, and if something goes wrong, you’re on the hook. Even for personal use, why would you cut corners on something that keeps your fairings attached and you on the road or in the air? I’ve been in this game for 10 years, selling fairing bolts to riders and pilots, and I’ve seen way too many guys get hurt because they tried to save a buck on bolts after a crash.
Now, I know what some of you are thinking: “But new bolts are expensive!” Look, I get it. When you just had to pay for a new fairing or a dent on your bike, every dollar counts. But here’s the thing—you can get quality fairing bolts at a reasonable price from a reputable supplier like me. I don’t sell cheap garbage that’ll rust or snap on its own, but I also don’t charge an arm and a leg. And think about this: a new set of bolts is way cheaper than a new fairing, let alone a hospital bill if a bolt snaps and causes a crash.
Wait, another angle: corrosion. If your crash happened in the rain, or the bolt got covered in road salt or aircraft de-icing fluid, reusing it is even worse. Those chemicals can seep into the tiny cracks from the impact, causing the bolt to rust and weaken over time. Even if you clean it off, the damage is already done. And let’s be honest—who has time to sand, clean, and re-coat a bolt after a crash? Just get a new one.
Let me wrap this up with a real story. A few months back, a guy named Jake came to my shop. He’d dropped his Yamaha R6 in a parking lot, going super slow, like 5 mph. He scraped the right fairing, and when he took it off, the bolt that held the lower corner looked straight, no scratches. He tried to reuse it, and when he tightened it, it snapped in his hand. He ended up buying a new bolt and a replacement insert for the frame, and that’s a $50 fix instead of a $20 bolt. If he’d checked it like he should’ve, he wouldn’t have wasted the extra money, but he thought it was fine because it looked good.
So, to answer the original question: Can fairing bolts be reused after a crash? The short answer is almost never. Unless it’s a super minor, no-impact incident where the bolt shows zero signs of damage (bends, scratches, thread wear), and you test it to make sure it holds torque, don’t do it. It’s not worth the risk of a fairing coming loose, a bolt snapping mid-ride, or worse—an accident that could hurt you or someone else.
If you need quality, affordable fairing bolts that meet all safety standards, hit me up. I’ve got titanium, steel, all sizes and grades for motorcycles and small aircraft. No cheap no-name garbage, just parts that’ll keep you safe when you’re out on the road or in the sky. Don’t cut corners on your safety—reach out to me to chat about your needs, and I’ll help you get the right bolts for your ride.
