Two of these screws fit perfectly into either side of the spindle of my square taper bottom bracket. They are standard size and a quality build, with a good hard plastic dust shield included (itโ€™s removable if necessary for your application). They even have some threadlocker already on them.I like getting four in the set as this gives me a second set for another bike or a backup set for my main ride.

Replaced a hard to reach 15mm screw on Shimano 600 BioPace crankset. The screws comes with rubber gasket and a metal washer all built in. This eliminates the need to have any washer or a top cap as it seals the hole perfectly. See the photo of it sitting nicely inside the crank arm hole. The threads have loctite preapplied on them and the machining of the threads is perfect. I had no problems installing it just by hands and then with 8mm hex key with minor torque. Perfect.
