🔍 Key Concepts

• Proper engagement of a tab/clip with a nut flat or side • Direction of the locking force relative to nut rotation • Full contact of the locking surface against the nut and structure

💭 Think About

• For each figure, ask yourself: if the nut tried to loosen, how would the lock actually stop it from turning? • Is the locking device bearing on a flat, solid surface of the nut, or only on an edge/corner? • Is any tab or clip bent in a direction that could be forced open instead of tighter if the nut turns?

✅ Before You Answer

• Verify that the lock bears on a flat face of the nut, not just a corner or point • Confirm the lock is supported by a solid backing surface so it cannot slip away as the nut turns • Check whether the lock’s orientation would make it tighter or looser if the nut tried to back off
