Some components, such as speakers or buzzers, have holes in flanges that

you can use to secure the component to the wall of the box with screws. Use

the flange holes as a template to mark the locations to drill holes.

Some components are meant to be panel-mounted but don’t have threads.

For example, in Chapter 11, we use a two-piece, LED panel-mount socket in

which one part of the socket slides through the hole and onto the other half

and snaps in place, securing the LED.

In some cases, you have to mount microphone cartridges that don’t come

with threads or snap sockets in the walls of boxes. Simply drill a hole that’s

just big enough in diameter to slip the cartridge in with a snug fit. If you’re

using a wooden box, the wall of the box should be thick enough to secure the

microphone cartridge. If you’re using a plastic box, you’ll probably need to

secure the microphone cartridge with glue.

Sticking things on the box

If you use screws to attach a component to a wooden box and you want to

put something else over the screw head, use a flathead screw, as shown in

Figure 4-16. When you don’t need to keep the surface flush, panhead screws

are just fine.
