groovejoint

groovejoint is a descriptive term used in engineering and design to refer to a joint or interface that uses a groove, channel, or recess to guide, align, or retain components. There is no universally standardized definition for groovejoint; its exact form varies by field, manufacturing process, and application. In different contexts, it may describe a woodworking profile, a metal extrusion fit, or a gasket groove.

In woodworking and cabinetry, a groove joint often involves cutting a groove along the edge of a piece to receive a corresponding insert, panel, or tongue, providing alignment and sometimes sealing. The concept is closely related to tongue-and-groove and dado joints, with the groove serving as a guiding feature rather than solely a mechanical lock.

In metal fabrication and modular framing, groove joints describe interfaces such as T-slots or U-grooves in profiles that accept fasteners, connectors, or sliding elements. These systems enable adjustable positioning, easy assembly and disassembly, and scalable construction.

In sealing and fluid systems, grooves machined into surfaces hold gaskets or o-rings; the groove defines the sealing geometry and tolerances.
