Special Washer category includes tab and keyed washers, countersunk washers, and spring tension washers. This category is called what?

• A. Lock Washer
• B. Special Washer
• C. Plain Washer
• D. Spring Washer

Answer: (B)

Washer categories are grouped by their function beyond simply distributing load. Tab and keyed washers, countersunk washers, and spring tension washers are all designed to provide features like anti-rotation, alignment with slots, seating in countersunk holes, or a built-in spring effect. These designs fall under a category focused on special applications and features, hence they are called Special Washers. Other options describe more specific or different roles: plain washers are just flat spacers, lock washers (including various locking types) focus on preventing loosening, and spring or tension washers are a separate class that provides spring action. The term that encompasses the listed types as a group is Special Washer.
