Harley-Davidson Sportster black stainless engine bolt kit. Made from A2 stainless steel these UNC socket cap screws won't go rusty like the stock bolts and being available in black is a must when blacking out your engine.
Fits Sportster engines 2004 Onwards
 
The kit is easy to fit with a bit of patience and we found the best way is to do one bolt at a time, you will need a set of Imperial allen keys preferably the ball end ones.
