TEKTON Flex-Head Ratcheting Combination Wrenches offer the speed and ease of a ratcheting box end that stays continuously engaged with fasteners, eliminating the need to re-fit after each turn. Smoothly pivoting through 180 degrees, the box end head holds any angle to slide onto fasteners. It is free to move with each stroke, allowing the wrench to navigate around obstructions along the swing path. A 6-point opening provides a sure, snug fit on hex-shaped fasteners so you can apply maximum torque without slipping off, preventing knuckle aggravation. To prevent round-off, the box end opening contacts and applies force to the flat sides of fastener heads rather than the corners. Equipped with a 72-tooth ratchet gear that needs just 5 degrees of swing arc to reach the next tooth position, it is fast and efficient when there is not much room to move. The open end is angled 15 degrees, allowing the wrench to be flipped over with each rotation to engage the fastener twice as often when you are working in tight spaces.
