ISO 8748 Spiral Dowel Pins

ISO 8748 is the Spiral Dowel Pins standard recognized as the International Organization for Standardization (ISO). Spiral Dowel pins made of standard and high-quality raw materials such as stainless steel, carbon steel, brass, mild steel, alloy steel and other materials. ISO 8748 Spiral Dowel Pins is a spiral spring metal structure. They work based on the principle of compression and expansion of the operation. The design of the spiral dowel pin ensures elastic and reliable performance. It is a metal sheet metal loop that is suitable for heavy-duty applications. This type of mechanical fasteners, ISO 8748 Spiral Dowel Pins are the most commonly used as a locking device in mechanical engineering. The ISO 8748 roll structure, that has one cut slot end inside the pin and another at the outside of pin, can be useful when a tight connection requires under high tension. ISO 8748 Spiral Dowel Pins have chamfered or tapered corner at both ends for easy insertion. Due to this, pin easy enter into the hole using a standard tool. The main advantage of the Spiral Dowel is that it provides accurate alignment with less stress and reduce the risk of splitting. They are used into a which the spiral pin is to be inserted shall be equal to the nominal diameter.

ISO 8748 Spiral Dowel Pins are available in a variety of Length, slot width, materials, thickness, diameter, tolerance, finishing and many other specifications. Various ISO 8748 used for different applications and projects. This International standard of Spiral Dowel Pins most commonly used for the different fastening, loosening and lighting application.

We also offer many ISO specification fasteners including ISO 8737 Taper Pins, ISO 1234 Split Pins, ISO 8744 Grooved Pins, ISO 8745 Parallel Grooved Pins and many other.
