For example, in one embodiment, the lock feature 105 may be a bump or protuberance and the head feature 107 may be a depression or recess or hole such that these two features are configured to engage with each other to retain a screw 104 in the screw opening 106. In certain embodiments, the lock feature 105 and the head feature 107 may together be consider a type of detent mechanism.
