Three matte-finish SAE flare nut wrenches on a hang tag

Apex Tool Group, LLC

Apex Tool Group 699850 3 Piece SAE Flare Nut Wrench Set

SKU CH-G938-VFBK1

A three-piece SAE flare-nut wrench set covering six common fitting sizes for brake, fuel and hydraulic lines

  • Three SAE flare-nut wrenches cover common fittings
  • Matte finish resists glare and corrosion on the job
  • Open-ended jaws grip fasteners without rounding corners
  • Compact three-piece set keeps essential sizes organised

Three-piece SAE flare-nut set

The Master Mechanic 699850 set contains three double-ended flare-nut wrenches in SAE sizes 3/8 by 7/16, 1/2 by 9/16 and 5/8 by 11/16 inches. A matte finish reduces glare and resists corrosion during daily shop use. The wrenches ship on a hang tag for easy pegboard storage. Professional technicians and DIY owners gain the exact openings needed for brake, fuel and hydraulic lines.

Open-end grip under sustained torque

Each wrench engages six points on the fitting, spreading load evenly to prevent rounding when high force is applied for long periods. The slim heads reach tight joints without slipping off under continuous pressure. Matte steel surfaces maintain grip even when hands or fasteners are oily. Users who need ratcheting action or metric sizes will require a different tool.

Questions about this item

How much force can I apply to the 11/16" flare nut wrench before it slips?

The 11/16" wrench is forged from alloy steel and heat-treated to resist rounding, so it handles the high torque needed for stuck brake lines and fuel fittings without slipping off the fastener.

Do I need a bench vise or pipe to extend the leverage on the 5/8" wrench?

The 5/8" wrench is 16 inches long, giving enough leverage for most flare nuts by hand; a cheater pipe is only needed for severely seized fittings.
