⚙️ Hardware Setup, Adjustments & FAQs

❓ How to know which side of the wrench to use (open-end or box-end)? cfg_01
The open-end jaw is ideal for access in tight spaces. The box-end (closed) offers greater contact and torque, making it more secure against stripping. Use the box-end whenever possible.
