General Motors, and other automobile manufacturers, have also begun using side-post battery terminals, which consist of two recessed female 3/8" threads (SAE 3/8-16) into which bolts or various battery terminal adapters are to be attached. These side posts are of the same size and do not prevent incorrect polarity connections.
The extractor is then inserted into this hole and turned in the direction opposing the stuck screw's original one, usually using a tap wrench. As the extractor is turned, the flutes on the tool dig into the screw, causing it to lock tightly and withstand the applied torque required to remove the screw. [1]

A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt.
A hex screw drive uses six-sided fastener heads, and the fastener is known as a hex head cap screw. It can be turned with an adjustable wrench, combination wrench and 6- or 12-point sockets. The hex drive is better than square drive for locations where surrounding obstacles limit wrenching access, because smaller wrench-swing arcs can still ...
A common size for cells inside cordless tool battery packs. This size is also used in radio-controlled scale vehicle battery packs and some Soviet multimeters. 1 ⁄ 2-, 4 ⁄ 5 - and 5 ⁄ 4-sub-C sizes (differing in length) are also available. Soviet 332 type can be replaced with R10 (#4, 927, BF, U8) or 1.5 V elements from 3 V 2xLR10 packs ...

IEC metric screw sized connectors is a family of electrical connectors defined by IEC that are named according to their ISO metric screw thread, namely M5, M8 and M12. [1] The number gives their outer screw thread diameter in millimeters as with the identically named screws.
Screw terminals, as individual connectors to a board at left, as a barrier strip with setscrews at top, and as a barrier strip with attached spade and loop lugs at bottom. A screw terminal is a type of electrical connection where a wire is held by the tightening of a screw.
