These Grade-8 cap screws are recommended for high stress bolting applications and are among the strongest grade of fastener available in steel. The Grade-8 bolt is compatible with Grade-8 nuts and washers of the same thread pitch and diameter. An alternative for using them without nuts is to install them directly into a compatible female threaded hole.
