➡ M5X16 DIN551
✅ M5x16 DIN 551 set screw – a standard part for locking elements on the shaft, useful in every workshop and machine service
✅ No head - after screwing in, the screw does not protrude above the surface of the element (e.g. hub, sleeve), so it does not interfere with other parts and allows for a compact system installation
✅ The slot for a flat screwdriver allows for quick assembly and adjustment using a standard screwdriver - no special keys required
✅ The flat point ensures even pressure on the flat surface of the shaft or element – minimizes the risk of cutting into the material and damaging the shaft compared to a tapered point
✅ Full thread along the entire length allows for free adjustment of the screw-in depth and reliable pressure in various thicknesses of walls, sleeves or hubs
✅ It works well as an adjustment element – suitable for both permanent locking connections and for points where periodic adjustment or service is required during operation.
