FLZOSPER 21mm Metric Wrench,12-Point Box End Head Combination Wrench Spanner

12-Point Box End Providing a sure, snug fit on hex-shaped fasteners, a 12-point box end resists slipping off while you work, saving aggravation and your knuckles. To prevent round-off, it contacts and applies force to the flat sides of fastener heads rather than the corners. 5-Degree Swing Arc A ratchet gear with 72 teeth requires just 5 degrees of swing arc to reach the next tooth position, so it's fast and efficient when there's not much room to move. The teeth of the ratchet gear are cut, not press formed, creating a crisp, precise profile that fully engages with the pawls and can't skip or slip under high stress. Angled Open End The open end is angled 15 degrees so the wrench can be flipped over with each rotation to engage the fastener twice as often in tight spaces.
