Special Open End Head for TBIH & TBX-12

Open End Head for TBIH Break-Over Torque Wrenches

Built for accessibility and efficiency, the open-end wrench provides quick access to fasteners in tight or restricted spaces. Its open-sided design allows it to easily slide around nuts and bolts, making it a go-to tool for machinery maintenance, electrical work, and field repairs. While ideal for fast adjustments, this wrench type requires careful handling under high torque to prevent rounding off fasteners. Ideal for quick adjustments, confined spaces, and applications where sockets or box-end 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.
