nonadjustsable open-end wrenches. Each wrench here has a fixed jaw on each end. The
longest wrench shown here has a 3/8-inch jaw on one end and a 5/16-inch jaw on the opposite
end; the smallest has a 13/64-inch jaw on one end and a 7/32-inch jaw on the opposite end.
The sizes included in a TK-105/G are very useful on the small nuts and bolts encountered on
chassis work, terminal boards, and lightweight mountings.
Figure 6. Wrenches: adjustable and open-end.
(2) Socket wrenches (fig. 7). A socket wrench is made up basically of two parts: a socket and a
handle. The TK-105/G has a metal box containing a set of sockets and handles. The sizes of
the sockets in this kit are suitable for radio mechanics and electronic equipment repairmen
working in the field. However, in production-line shops, such as those that do general
support maintenance and depot maintenance, the maintenance man who has to do assembly
or disassembly hour after hour may be equipped with ratchet handles, speed handles,
extensions, flex-joints, and other attachments which take sockets essentially similar to those
shown in figure 7.
(3) Spanners (fig. 8). This spanner wrench set consists of five pressed steel spanners of several
sizes, together with a handle. They are specially designed for the purpose of tightening and
unfastening Amphenol connector locking rings. Such rings serve to hold the receptacle
portion of the Amphenol connector to the chassis of an equipment or equipment component.
Power cables, audio cables, and other types of interconnecting cables often have Amphenol
plugs
