Review on Wanyifa Titanium M5 M6X12 15 20Mm Button Torx Head Bolt Screw For Bicycle Motorcycle Pack Of 4 (M5X12Mm by Bob Fasho

I used these bolts on my full suspension mountain bike. And it wasn't so much the weight but the strength of the material combined with the low head profile that made me want to use this titanium buckle. First off I believe they are titanium as one of the reviewers mentioned, they produce brilliant white sparks when sharpened (I only had to trim them a bit to match the thread depth in the bike) as well as the sound they make when one tapping them together, they're very similar to ceramic, which means they're not steel, and they have a tactile hardness you don't get with steel. I have 4 link rear suspension and overall I like this bike and the way the suspension works, but there were a few bolts between the top tube and down tube for a mounting point, right where my knee goes when I press the pedal. . Maybe that doesn't apply to most people since I'm a bit small, but I hit these studs with the inside of my knee when I was spinning or trying to dodge a tree or whatever moved the bike a little bit. - in the middle below me. The placement of these anchors wouldn't be too bad, but the original bolt arrangement was a standard height socket head cap with a big ol' socket underneath to spread the load, and it stuck out REALLY FAR. So I searched for low profile alloy steel bolts but found nothing. I came across something similar but made of aluminum. I figured for the application that I would NOT want to risk using an aluminum fastener. If I fail this reversal during a decent trade I will have a bad day. So the aluminum is over. There were plenty of stainless options, but stainless steel is notorious for cracking right under the head when things are constantly being tightened, meaning I could get stuck in my frame and had to drill a hell of a lot to remove it. Also, this poses a safety concern as I sometimes take it apart for maintenance and I don't want to lose a bolt head right after a repair or whatever while I'm driving. So no stainless steel. I finally found this bolt by accident just before my scroll finger fell off while browsing all the industry sites (like McMaster and Granger) and damn I'm glad I did. It fits the frame snugly and snugly while maintaining a very low profile. The wide head is about the same diameter as the original bushings the company used behind the smaller head bolt, so I know it distributes the load pretty well. Haven't had any problems with it so far, I've removed and retightened the bolts several times and inspected the fairing only to find no signs of tension (such as wrinkles, tears or whitening of the fairing just under the head). , and I've had some epic rides of 20+ miles on beautiful glacier hill trails in northern Michigan without even realizing they were there, meaning they're perfect for my needs. And not that it matters, but those original bushings and bolts looked like warts or Frankenstein collar screws sticking out of a beautiful, sexy, curvy frame. These bolts solve the problem with nice styling, their flex matches the flex of the frame, but the muted black finish doesn't scream "Look at me!" (get the oil slick version if you want it lol). When I've hit them while riding since, I really haven't noticed as the curved profile would deflect rather than hit my knee. So no more bruises on the inside of the knee as a bonus. And one more word, if you're using them in high-vibration applications like cycling, be sure to use a small dab of medium-strength threadlock. To be honest this is a very good bolt and 100% value for my needs. Bonus, I have two extras. I don't know why, I don't think I need to replace them but I'll keep them just in case. I'm super thankful I can even get something like this. Highly recommend this product if you are looking for a high strength, low profile (and low corrosion to boot) solution.
