Wera Joker Spanners


Open end needs only 30 degrees of movement. Ring ratchet is an unusual 80 tooth design needing only 4.5 degrees to click. The open end also has a serrated plate serving two purposes. On top it stops the jaw dropping down off the head as it unscrews, on the bottom it helps grip the head to prevent rounding the shoulders. Product demonstration video below.
