Double-ended Design: Featuring two openings, each with a different size, our double open end wrenches can accommodate two different sizes of nuts or bolt heads.

Adaptable to Two Sizes: The double-ended design lets you work on two different sizes of nuts or bolts without needing to grab another wrench. It's a real time-saver and makes your job way easier.

Precise Tightening: The double box wrench's larger contact area with the nut or bolt head allows for a more secure and precise tightening force.
