640nm Shear Wrench For Narrow Space

In the steel structure, bridge construction, and other industries requiring high-strength bolt fastening, what is the most persistent headache? Due to project requirements, bolts are often situated in locations where they are either extremely difficult to turn or-more commonly-where the available space is so confined that standard wrenches simply cannot fit, leading to significant construction challenges.

Hanpu's F-20 Folding Manual Shear Wrench was specifically engineered to resolve these spatial constraints encountered during construction. Its standout feature is its collapsible extension arm: when a longer lever arm is required for the job, it extends to a full length of 485 mm, delivering impressive gripping power and torque output (up to 640 N·m). However, its greatest asset is its remarkably compact design; when faced with particularly cramped corners, you can simply fold the wrench in half-instantly reducing its length to 345 mm-allowing it to effortlessly squeeze into even the tightest nooks and crannies.

Whether you're dealing with M12, M16, or M20 metric nuts-or their imperial counterparts in 1/2", 5/8", or 3/4" sizes-this tool handles them all with ease, eliminating the need to constantly swap out attachments. Weighing in at just 2 kg, the unit is only slightly longer than an arm when stowed away; it tucks neatly into a car trunk or the corner of a toolbox without taking up any space. For workers who are constantly on the move between job sites, or those tasked with tackling particularly stubborn or tricky bolts, this is an indispensable tool that delivers tangible improvements in efficiency.
