− | + | Appliance makers sometimes use strange screw heads to hinder attempts from users to remove appliance covers. Users usually have handy screwdrivers for the first two screw types drawn, Phillips and Slot. More advanced users usually have some less standard drivers, such as Torx or Allen, however appliance makers keep designing increasingly strange screw heads and users keep acquiring increasingly strange screwdrivers. | |

The reference to Amazon is presumably a suggestion to search Amazon.com for the screwdriver. A number of star-shaped screw heads exist, notably the six-pointed {{w|Torx}}, and Apple's rounded {{w|Pentalobe screw|pentalobe screw}}, although there is no popular design that uses the 5-pointed star shape depicted in the comic. Torx screws are common in automotive applications — Phillips heads are designed to "cam out" at high torque to protect the screw, whereas Torx do not — and on bicycles where a higher tightening torque is needed than hex screws can support. They are also commonly used on disk brake mounts and in Smartphones. |

| The head of a screw can be stripped by overuse, tightening the screw too much, using the wrong size screwdriver, or other misuse. As the driving surfaces wear away, removing the screw becomes more difficult, and the added pressure needed to drive the screw usually damages it further. | | The head of a screw can be stripped by overuse, tightening the screw too much, using the wrong size screwdriver, or other misuse.

− | The addition of "cursed" and " | + | The addition of "cursed" and "-1" in the titles is a reference to various role playing games (e.g. Dungeons and Dragons), where magical "cursed" items appear frequently. This often makes the cursed equipment (in the case of armor or weapons) incredibly difficult to remove, as it will cling to the wielder. Similarly, the cursed Phillips Head screw becomes difficult to remove due to the stripped head. |
− | The " | + | The "-1" refers to the damage of the screw head. In role playing games, items such as weapons and armor may have an "enchantment", with a positive enchantment making the item more effective, and a negative enchantment making the item less effective. Negatively enchanted items are often also cursed, as is the case with this screw head. The "-1" does not appear to be a reference to a Philips bit-size number, as those are always positive. |
+ | Notably, the stripped screw bears a resemblance to a {{w|List_of_screw_drives#Pozidriv|Pozidriv head}}, a modified version of the Phillips head designed to resist slipping and subsequent stripping. Using a Phillips head screwdriver in a Pozidriv screw is very likely to damage the screw head and cause a real Pozidriv screwdriver to no longer mate correctly. | ||

Rivets cannot be removed with a screwdriver, they must be "drilled out". Some bolts also have rounded rivet-style heads, though, with no means of gripping them. |

The amount of force on the two screwdriver shafts needed to turn the hex bolt will probably exceed the strength of human hands - the attempt would most likely only result in causing your hands to cramp or causing the screwdrivers to slip and cause further injury. |
