Button Head Bolts (M5 for water bottle bosses)

Button Head bolts are good for water bottle cages, or filling any M5 hole on your frame that isn't be used for a rack.  Basically, these bolts are lower profile and nicer looking than a socket head M5 bolt, but you can't torque as hard on them without rounding them out.  So don't use them to install a rack, but they're good for bottle cages or just filling holes.  Put a bit of grease or beeswax on the threads before inserting.  Stainless Steel.   12mm threaded section.  Sold individually.
