Question 2140 Deck General

The correct answer is C) a threaded bolt, locknuts, and cotter pins. Safety shackles are fitted with a threaded bolt, locknuts, and cotter pins to ensure secure and reliable connections. The threaded bolt provides a strong, adjustable fastening, while the locknuts and cotter pins prevent the bolt from loosening over time. This combination of features is the standard design for safety shackles used in maritime applications to maintain the integrity of critical connections. The other options are incorrect because they do not fully describe the components of a safety shackle. Option A) round pins and locknuts is missing the threaded bolt, and option B) a threaded bolt alone is lacking the locknuts and cotter pins. Option D) a round pin with a cotter pin does not include the threaded bolt required for a safety shackle.
