malethreaded

Malethreaded is a term used to describe an object that carries external threads, i.e., a male thread, rather than an internal thread. In formal engineering usage, the more common terms are male-threaded or externally threaded. The form malethreaded appears in some catalogs, product descriptions, or informal writing to distinguish external from internal threads. It is typically used to indicate that a component will mate with a female-threaded part such as a nut or tapped hole.

Common malethreaded components include bolts, studs, and threaded rods, as well as male-threaded fittings used in piping and pneumatic systems. These parts are designed to be fastened to a female-threaded counterpart with engagement over a specified length. Thread profiles are defined by diameter and pitch, such as metric M6 x 1 or imperial 1/4-20. The orientation of threads (external) is opposite that of nuts and tapped holes.

Manufacturers specify tolerances and fit classes for threaded connections to ensure strength and ease of assembly. Improper mating can lead to cross-threading, stripped threads, or seizing, especially if threads are damaged, contaminated, or mismatched in size or pitch. Proper torque, lubrication, and cleanliness help avoid issues. When replacing malethreaded parts, matching both nominal size and thread pitch to the mating female thread is essential.
