WanyifaTitanium Ti Allen Hex M5x16 18mm Tapered Head Bolt with Washer Screw for Bicycle Stem Parts Pack of 6 (Ranibow, M5x18mm)

Top bolt for reference of a bolt that’s actually blue. These are the ones below that are a faded violet color.If you’re buying these to have some color on your bike (or whatever you use them for) I would look elsewhere. The blue ones I bought were nothing like the image. They were more of a very faded purple color at best. After a month they’ve turned silver from the sun. Very disappointed.If you just need a ti m5 bolt and don’t care about appearance, they’re great.

My stock Specialized stem bolts were rusting and looked terrible, so I started searching for a set of bolts to replace them and came across these titanium rainbow bolts. I was blown away with the quality and appearance of them when they arrived. They seems as strong as the steel bolts and they look 100x better than the rusty originals. I liked them so much I’m in the process of replacing all my steel bolts with these. Thanks Wanyifa for making great quality products at a very reasonable price!

Had a stripped screw, needed a replacement. These screws seem to work well.

Very nice bolts! We’ll see how they hold up but they are perfect for my bike!

High quality bolts for a decent price

Finish is much more durable than on other titanium fasteners I’ve bought. 300 miles on mountain bike and still no flaking.

Worked perfect in my specialized s works stem. Seem great to me so far. Also, s works stems use m5x18.... couldn’t find that info for the life of me so hope this helps.

They will strip. Don't let them touch your bike stem.

Pretty nice.
