Heavy Duty Metric Flare Nut Crowfoot Wrench Set | Built Supply Co

The unique crowfoot shape securely engages nuts to prevent slipping and rounding during use. When paired with ratchets, extension bars, and torque wrenches, it delivers reliable torque to loosen and tighten large nuts and bolts in areas where standard wrenches cannot fit. Constructed from premium chrome molybdenum (Cr-Mo) steel for exceptional hardness, durability, and wear resistance. Each wrench features a black oxide finish for enhanced corrosion resistance and long service life under heavy use.

Applications

Designed for use in tight, confined, and hard-to-reach spaces , this crowfoot set greatly improves repair efficiency. It is widely used for servicing flare nuts on power steering lines, fuel lines, O2 sensors, brake lines, hydraulic lines, and other hard-to-access fasteners.

Usage Tips

This set is rated for use with torque wrenches up to approximately 100 ft-lbs . Always increase torque gradually during use; avoid applying excessive torque, as this may result in damage to the crowfoot wrenches.
