Introduced: September 1968

Classification Context

Section:: MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
Class:: ENGINEERING ELEMENTS OR UNITS; GENERAL MEASURES FOR PRODUCING AND MAINTAINING EFFECTIVE FUNCTIONING OF MACHINES OR INSTALLATIONS; THERMAL INSULATION IN GENERAL
Subclass:: DEVICES FOR FASTENING OR SECURING CONSTRUCTIONAL ELEMENTS OR MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS OR WEDGES; JOINTS OR JOINTING

Description

F16B encompasses mechanical fastening devices and joining methods used to permanently or temporarily secure structural and machine components. This includes threaded fasteners (bolts, screws, studs), non-threaded fasteners (nails, rivets, pins), and mechanical locking devices (circlips, retaining rings, wedges). The classification also covers clamping and holding mechanisms (clamps, clips, brackets) and joint designs that enable assembly and disassembly of machine parts and structures. Adjacent classes such as F16D (seals and packings) and F16G (springs) are excluded, as are specialized fastening methods covered under welding or adhesive bonding in other sections.

Scope Notes
