Schroefgleuven

Schroefgleuven, a Dutch term that translates to "screw slots" or "screw grooves," refers to the indentations or channels on the head of a screw designed to accommodate a corresponding screwdriver. These slots are a fundamental aspect of screw design, dictating the type of tool required for installation and removal. The shape and size of the schroefgleuf are critical for ensuring proper engagement with the screwdriver, preventing slippage, and allowing for the efficient transfer of torque.

Various types of schroefgleuven exist, each with its own advantages and applications. The most common include the straight slot, also known as the flat-head slot, which is a simple linear indentation. The Phillips head slot is a cross-shaped recess designed to cam out under excessive torque, preventing overtightening. Pozidriv slots are a further refinement of the Phillips head, featuring additional smaller slots to improve grip. Torx slots, shaped like a six-pointed star, offer excellent torque transfer and resistance to cam-out. Other less common types include Robertson (square) and hex (internal or external hexagon) slots.

The selection of a schroefgleuf is often determined by factors such as the required torque, the material being fastened, and security considerations. Specialized tools are manufactured with corresponding tips to fit these various schroefgleuven. The evolution of schroefgleuven reflects a continuous effort to improve fastening efficiency, reduce cam-out, and enhance the overall performance of mechanical connections.
