🔍 Key Concepts

• Different wrench head shapes and how they contact the nut or bolt • The difference between a wrench that grips on two sides versus one that grips on all sides • Which wrenches are designed to slip on from the side versus slide over the top of the nut/bolt

💭 Think About

• Which of these wrenches would be best to prevent rounding off the corners of a nut, since it grips on more than just two flats? • Think about how you would remove a nut in a tight space where you cannot slide the wrench sideways onto the flats— which type of wrench could drop straight over the nut? • For each option, picture the wrench jaws or ring: does it leave the nut partly exposed or does it form a nearly complete circle around it?

✅ Before You Answer

• For each wrench type, mentally draw the shape of the working end (jaws or ring) and how many sides of the nut it contacts • Confirm which wrench types are open on one side versus having a closed loop around the nut • Eliminate any wrench that mainly adjusts in size (movable jaw) instead of having a fixed, fully surrounding head
