    What forming processes does alstertaler schrauben & präzisionsteile gmbh offer for special screws?

    In the production of our special screws, we rely on metal-cutting or non-cutting forming, which in turn distinguishes between hot forming and cold forming. Metal-cutting forming is particularly suitable when tighter tolerances are required or special geometries are to be implemented. Cold forming (also cold extrusion) is the first choice for large screw quantities whereas hot forming is suitable for the production of particularly thick (> M27) or long (> 30 cm) screws. Take a look at the respective sub-pages on our website for detailed information on the forming processes we offer.

    What are stud bolts suitable for?

    stud bolts

    These metal studs are firmly connected to a structural element with their cutting circle surface. This makes it look like they are “standing” on the component.

    Several machine components can be connected to each other via the stud bolts. Studs are used as fastening parts in various fields, for example in mechanical engineering or electrical engineering.

    They offer the advantage that they remain in the machine part and thus minimize the risk of damaging the fastening thread by frequent tightening and loosening.

    Why use hanger bolts?

    hanger bolts

    Hanger bolts are special fastening screws that have a dowel thread at one end and a metric thread instead of a screw head at the other end. Between them is a hexagon so that the screw can be tightened using an open-end wrench. The advantage during assembly is that the screw axis only needs to be accessible from the side in order to set the nut – easily and permanently even in the tightest of spaces. In addition, the screw can be easily dismantled without unscrewing the dowel screw connection and damaging it as a result. Hanger bolts are versatile and used, among other things, for simple fastening of construction elements of various types to concrete, masonry or wood. A typical field of application is stair construction.

    What are triangular screws?

    The so-called triangular screws from the range of security technology have, as the name suggests, a special appearance. The unusual triangular head shape of these special screws gives them their name and requires a special key to loosen or fix them. Because of this, it is not possible for unauthorized persons to easily move the special screws. In addition, they usually have a metric thread with a shank. Thus, triangular screws are often used for door locks or parking lot bars, but also for barrier posts in pedestrian areas. Due to this, they are also known as bollard bolts. Due to their everyday presence in public spaces, they have a high recognition value
