The amount of adhesive overlap between pinchweld and windshield is called what?

• A. Bite
• B. Bead
• C. Adhesion
• D. Aging

Answer: (A)

The concept being tested is how we describe how much adhesive actually overlaps the bond area between the pinchweld and the windshield. That overlap amount is called bite. Bite refers to how far the adhesive wets and extends over the joint where the glass meets the vehicle body, which determines the effective bonding surface and seal.

Understanding bite helps you gauge whether there’s enough adhesive engaged to create a solid seal and proper adhesion, without excessive squeeze-out. The other terms aren’t about overlap length: the bead is simply the continuous line of adhesive laid around the edge, adhesion is the strength of the bond at the interface, and aging refers to changes in adhesive properties over time or with environmental exposure.
