these screws help you get a nice chain tension by moving the dropout back, they can get rounded off and cause you a whole load of grief. adjust with an M3 Allen key as per the original..(don’t use the ball end…that’s what causes the rounding off.)
straight replacement, quality stainless steel..
for the UA4 with black moveable dropouts, come in a set of two grub screws..
for the UA2 with dropouts in the frame and a little black plate with one adjuster, one screw.
