Hex Wrenches
• Ball-end hex drivers can be used to at an angle.• T-handle hex wrenches give you more torque.
All VEX parts (except the joystick) use two
sizes of hex keys (3/32 & 5/64).
Each robot kit has two hex keys.
These hex wrenches are better.

Pliers
slip-joint
needle-nose
Use pliers to grasp, hold, and bend.
Using pliers to turn nuts or screws will scratch nuts and damage the threads on screws.
Remove stripped screws by grasping their heads and turning with a pair of pliers.

Vise
• Use to bend or hold metal.
• Jaws can crush things.
• Clamp to a heavy table or bench.
• Do not clamp to a student desk!
The vise won’t fit in the toolbox.

Safety Glasses
• You must wear safety glasses when working with metal.
• So must everyone else nearby.

Bending Metal• Mark (with a marker) where you want the metal
to bend• Secure in a vise so the jaw closes just below the
bend-mark.• Tap with the hammer until the metal bends at
the desired angle.

Hacksaw
• Measure (count holes or use a ruler)
• Mark (use markers on metal)
• Remeasure: “measure twice, cut once”
• Secure in a vise
• Place hacksaw on mark and pull backwards several times to start a groove
• Pull back & forth to cut
