Open End Interchangeable Heads English Units of Measure
Need 3D rendering of our heads? Email our Customer Service team.
Note: All of our open end heads and ratcheting open end heads have the U-bottom design. We changed from the V-bottom to to the U-bottom to increase durability.
From an engineering standpoint a rounded corner distributes the stress vectors more evenly than designs that have intersecting planes.
If for some reason you want the V-bottom design, we can make that for you as a special.
Different pricing, minimum order quantities, and increased lead times apply.
