slotandgroove

Slot and groove is a general term used to describe a type of mechanical joint or connection in which a groove or slot on one part interlocks with a corresponding feature on another part. This arrangement is used to achieve alignment, guidance, and, in some cases, sliding motion between components. The concept appears across woodworking, metalworking, and plastic fabrication, and it can be implemented in many forms depending on the materials and the desired function.

In woodworking, a groove is often cut into the edge or face of a board to receive a pin, tongue, panel, or insert. The resulting joint provides precise alignment and can be used to assemble drawers, cabinet frames, or paneling. In metal and plastic applications, slot and groove configurations can guide moving parts, accept fasteners, or serve as tracks. A common metal example is the T-slot system in aluminum framing, where a T-shaped groove accepts bolts and slides for adjustable assembly.

Common types and variations include straight slots that receive a pin or slide component, and groove features designed to create a keyed or guided fit. T-slots and other speciality geometries expand the concept to track-and-fastener systems used in modular furniture, machine frames, and industrial equipment.

Key considerations when designing or selecting a slot-and-groove connection include material strength, tolerances, clearance, ease of assembly and disassembly, and the intended load direction. Properly implemented, slot and groove joints provide reliable alignment and guidance with relatively simple fabrication.
