PROWHEEL Bike Hex Crank Arm Fixing Bolts Spindle 8mm Allen Key Bolt Screws Capless Bottom Bracket for Cycling Bicycle Axle Fits Many Bike Cranksets

Replaced worn crank fixing bolts with these. Added blue lock tight and installed with an Allen wrench. Exact fit.

Fast shipping. Product works perfectly.

Pure steel and fits in nicely. Would be nice if it's sold with installation allen key.

Perfect fit. Good quality. Thank you.

Perfect replacement for the crank arm bolts on my GT performer. Came with thread locker!!

I was able to use these bolts to replace an inner nut that was exposed to moisture and had started to rust. These bolts were able to replace both the outer cover and the inner nut at the same time while keeping moisture out of the crankset. I do really like how it's only one specific bolt that I have to remove now instead of having to deal with the cover and the nut separately. Do keep in mind that these do need quite a bit of torque to tighten, or else they tend to get loose when you try to ride them -- I had to tighten mine with a leverage bar to make sure they were properly on all the way.

A+

I bought this on a limb hoping it would fit my step sons bike that we just got him for his birthday, it random fell off which we got it at Walmart a few months back. I’ve had stuff break and it always seems tough replacing parts these days. . . I bought these after looking up the most common crank bolt for mountain bike and booom for the first time I bought the right thing first try lol. This is the only reason I’m taking the time to write an honest thorough review 😂 god bless you all
