Hex Head Cap Screws

What is the difference between a hex bolt and a hex cap screw?

The primary difference between a bolt and a cap screw is the way in which they are installed. A hex cap screw is inserted by twisting the head of the bolt to assemble and tighten, whereas a bolt is installed by turning a nut to tighten the fastener.

How do you remove a hex cap screw?

• Use a rotary tool and grinding wheel to create a slot in the screw's head, and a flathead screwdriver to turn the screw.
• Alternatively, clamp a locking plier set onto the head and use it to turn the screw.
