MX Fuse Holder, Screw Cap, Flame Retardant (MX-407A)

A fuse protects the rest of a circuit, but the holder itself sitting right next to a wire carrying current is worth building out of something that won't readily catch fire if something does go wrong. This MX holder's flame-retardant housing gives that extra margin over a standard plastic holder, while still using the same simple screw-cap design for swapping a fuse without tools.
