Hexagon head screws manufactured according to drawing
Screw diversity with technical precision.
In addition to our wide range of standard parts, we also manufacture special hexagon head screws exactly according to drawings and test plans. We precisely implement modified head shapes, individual shank lengths, special threads, special strength classes or unusual materials according to your specifications – from individual pieces to series production. Our many years of experience at ASO Schrauben guarantee you a tailor-made connection solution for every technical challenge. On request also with factory certificates, material test certificates and acceptance tests.
Materials & Surfaces for the highest hexagon head screw requirements
The selection of the right material is crucial for the performance and service life of a hexagon head screw. Depending on the application, different metallic materials are used. Our hexagon head screws are available in various materials and coatings:
Steel plain / galvanized – cost-efficient & proven
Stainless steel A2 (V2A) / A4 (V4A) – for particularly humid, salty or aggressive environments
Black hexagon head screws – galvanically galvanized, burnished or phosphated
Special materials – e.g. heat-resistant steels or duplex steels
You can find an overview of all available materials on our separate material page
Specialist for special fasteners in pressure equipment construction
We offer you reliability in safety-critical applications.
A particular focus of ASO Schrauben is the production of special fasteners and custom fasteners for pressure equipment. Our fasteners are used wherever maximum safety, material quality, and manufacturing precision are required – for example, in pressure vessels, flange connections, heat exchangers, valves, or steam systems, in turbine construction, and in classic mechanical engineering.
Thanks to many years of experience and modern manufacturing technologies, we produce fasteners according to drawings or special standard specifications – starting even from a quantity of 1!
Our production meets the strict requirements of the Pressure Equipment Directive (PED 2014/68/EU) and relevant regulations such as AD 2000-Merkblatt W0. The corresponding certificates (e.g. 3.1 / 3.2 according to EN 10204) document the quality and traceability of our products – a clear added value for safety-critical applications.

Good to know: Hexagon head screws in detail
Hexagon head screws are screws with a hexagonal screw head, which is designed for actuation with a wrench or a socket. They enable optimal power transmission and high tightening force – ideal for powerful screw connections in mechanical engineering, plant construction and steel construction as well as in crafts. Due to their very good torque transmission and good accessibility when tightening, they are also suitable for assembly in tight spaces. Hexagon head screws are considered durable, reusable and detachable. At ASO Schrauben, they are available in various versions to reliably cover a wide range of applications and requirements.
- Hexagon head: enables powerful assembly and disassembly with standard tools
- External thread: metric thread according to DIN/ISO standard, mostly with partial or full thread
- Standards: Common standards are DIN 933 (full thread), DIN 931 (partial thread), ISO 4017 (full thread), ISO 4014 (partial thread), as well as DIN 960
- Materials: e.g. steel (galvanized, thick-layer passivated, burnished, black), stainless steel (A2, A4), special materials
- Strength classes: e.g. 8.8, 10.9, 12.9 for steel, depending on the load requirement
We manufacture everything for you - whether according to European or international standards!
Our hexagon head screws are used where standard solutions do not fit – for example, at high pressure, extreme temperatures or aggressive media. Special fasteners made of special TÜV tested pre-material are often the only solution in the industry to reliably implement complex, safety-relevant applications.
Areas of application of our hexagon head screws and their advantages
Hexagon head screws are used in a wide variety of industries: Mechanical engineering, plant construction, pipeline construction, steel construction, vehicle technology, pump industry and compressors, among others, hexagon head screws in sizes M6 – M120 are used – for example, for connecting steel beams, flanges, engines or machine parts.
Your advantages:
- Fast & secure screw connection
- High tensile strength (e.g. 8.8 / 10.9 / 12.9)
- Resistant to heat, corrosion & mechanical stress
- Also as stainless steel hexagon head screws A2 / A4 for outdoor use and/ or chemical stress
Our other types of fasteners
Special fasteners and custom fasteners can be designed in very different designs and functional types. Our common fasteners types include expansion bolts, threaded rods, and stud bolts, which are often used in pressure equipment or flange connections. Other variants include cylinder head fasteners, eye bolts, or special fasteners with special thread forms. The combination of different head shapes, thread types, and materials creates highly specialized fasteners that are precisely tailored to your requirements.
