• Explain when specific fasteners are used in 
vehicle construction
• Explain bolt and nut torque values
• Summarize the use of chemical fasteners
• Identify hose clamps
Introduction
• Fasteners are the thousands of bolts, nuts, 
screws, clips and adhesives that hold a vehicle 
together 
• Must be able to identify and use fasteners 
properly
• Each fastener is engineered for a specific 
application
• Always replace a fastener with exactly the same 
type that was removed from the original 
equipment manufacture (OEM) assembly

Bolts
• Bolt is a shaft with a head on one end and 
threads on the other
• Cap screw is a high-strength bolt
• Bolts and cap screws are named after the body 
part they hold
– Fender bolt, hood hinge bolt, etc.
• Also named after the shape and head drive 
configuration

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
