Special Screws in Detail
We offer a wide range of special screws — from triple-square and stud screws to fully customized fasteners.
They are manufactured from various materials, including steel, stainless steel, titanium, Inconel, and brass. Flexible logistics solutions, such as framework orders, warehousing, and just-in-time delivery, ensure that your parts are always available.
Special screws
At our company, special screws, custom parts, and fasteners are manufactured precisely according to drawings. We reliably produce triple-square screws, studs, and threaded rods with high quality. These components are suitable for mechanical engineering, metal construction, and electrical engineering applications.
Cold forming
Cold-formed screws and custom parts are manufactured according to drawings. Cold forming produces high-strength, dimensionally stable components such as bolts, pins, threaded parts, or rivets. They are particularly suitable for series production in mechanical engineering, the automotive industry, and electrical engineering.
Hot forming
We manufacture hot-formed screws and fasteners precisely according to your specifications. By forging above the recrystallization temperature, particularly complex head geometries can be produced. This process is ideal for small to medium series production with flexible design options.
Machining technology
Using precision machining, we manufacture special screws, bolts, and fasteners exactly according to drawings. Machining allows for very fine tolerances and complex geometries — ideal for small to medium series with individual requirements.
Anchor bolts
We manufacture anchor screws and stud screws from durable steel, stainless steel, or special materials.
Our screws carry heavy loads, reliably secure foundations or steel structures, and are available in a wide range of sizes and surface finishes.
Expansion bolts & nuts
Tension screws, expansion bolts, and expansion nuts according to DIN 2510 provide elastic fastening solutions with an expandable shank that extends in a controlled manner under load. The connection remains stable under temperature fluctuations — for example, in engine or mechanical engineering applications.
T-Bolts
Our T-bolts (hammerhead screws) are manufactured precisely according to drawings — available in numerous variants and materials such as steel or stainless steel.
These fastening solutions are particularly suitable for mounting rails in machinery, power plants, or automotive applications, providing high load capacity and flexibility.
Titanium screws
Titanium screws offer maximum strength with minimal weight and excellent corrosion resistance. For individual requirements, we manufacture precise screws, bolts, and fasteners in titanium — ideal for aerospace, medical technology, or high-performance constructions.
Stud bolds
lstertaler stud screws are cylindrical fasteners with threads on both ends — extremely strong and precisely manufactured.
We offer numerous standard and custom variants in various materials and surface finishes for applications such as mechanical engineering, steel construction, or automation.
