Bolts (continued)
• Bolt head is used to tighten the bolt
• Socket wrench fits over the bolt head
• Some metric/SAE sockets are very close in size
• Improper wrench or socket size could strip or 
round off the both you are working on
– This could damage your tools or even cause an 
injury if the tool slips off
