Special Flare End Head for TBIH & TBX-12

6-Point Hexagon

Flare End Head for TBIH Break-Over Torque Wrenches

The flare-end wrench is engineered for secure fastening around brake lines, fuel lines, and other fittings with obstructions. Its specialized open-head design allows easy access while wrapping around five sides of a hex fastener for a firm grip. This reduces the risk of rounding off edges, especially on softer materials, making it perfect for automotive and aerospace applications. It is ideal for brake lines, fuel lines, hydraulic fittings, and confined spaces where traditional wrenches can’t reach.

NOTE: The NEW open, box, and flare heads for the TBIH and TBX-12 models are made from 17-4 PH stainless steel, ensuring exceptional strength and corrosion resistance. Please note this material specification is exclusive to the new heads and does not apply to previous versions or other wrench head types.

NOTE: This is part of a rolling transition during the first half of 2025. As new heads are released, the new part numbers (starting by #069...) will become available on our website. The new head design is identifiable with the Mountz logo on the bottom section of the wrench head. The prior design does not have the Mountz logo on it.

NOTE: Head interchangeability is intended for use during recalibration to allow reconfiguring tools for different applications. They are not intended to be interchanged as a normal part of a manufacturing process.
