Which item is not a fastener?

• A. Eye bolts
• B. Anchor bolts
• C. Self tapping bolts
• D. Gaskets

Answer: (D)

Knowing the difference between fasteners and seals helps identify the item that isn’t a fastener. Fasteners are used to join parts or provide attachment points. Eye bolts are threaded pieces with an opening for a lifting or securing line. Anchor bolts are embedded into concrete to hold structures in place. Self-tapping bolts are designed to cut their own threads as they’re installed. A gasket, on the other hand, is a sealing material placed between mating surfaces to prevent leaks; it doesn’t fasten or secure parts. So the gasket is not a fastener.
