⚙️ Hardware Setup, Adjustments & FAQs

❓ What is the difference between using the box end and the open end of the combination wrench? cfg_01
The box end provides greater contact with all sides of the fastener, ideal for applying torque. The open end is faster for turning fasteners in spaces where the box end won't fit completely, but can damage corners if excessive force is used.
