Furniture industry
Screw manufacturer for the furniture industry and series production. Made in the EU, stable supply, technical support.
Interwolf is a European manufacturer of screws for the furniture industry, specialising in series production and customised technical solutions. Our components are intended for furniture manufacturers, assembly systems and assembly lines where joint reliability, repeatable quality and stable supply are key.
The screws are designed for use in chipboard, MDF, solid wood and other composite materials. We also adapt the thread geometry to the thickness and density of the board, ensuring an optimal hold in the material and reducing the risk of cracks and damage during screwing.
In self-assembly furniture, where the joint is often visible, the appearance of the screw head and surface matters as much as its function.

A European partner for long-term cooperation
As a manufacturer with our own production in the EU, we provide a stable supply chain, shorter logistics routes and technical support. Our goal is long-term cooperation with manufacturers who need a reliable supplier of mechanical components for series production.
Construction
The typical screws we supply to this industry are so-called drywall screws: medium-diameter screws in various lengths, with a characteristically shaped head specially designed for flawless fixing of plasterboard.
The purpose-designed thread allows fast, easy and reliable screwing and ensures a firm hold and long-term joint stability. Thanks to the optimal combination of shape, material and precise manufacturing, they enable efficient installation and save time on site and in drywall construction.
Our drywall screws are a reliable choice for professionals and anyone looking for a high-quality, safe and durable solution.
Electrical industry and household appliances
Interwolf makes screws for electronic devices, small household appliances and white goods. Solutions for plastics, precision, RoHS-compliant finishes and stable production in the EU.
Interwolf makes screws for electronic devices, small household appliances and white goods, where precision, mechanical stability and controlled assembly are key. Our screws are used in vacuum cleaners, mixers, washing machines and dryers, pumps, housings of electronic components, computer equipment and other devices that require long-term joint reliability.
The screws are available in the same size range as our standard product range (2–8 mm). Since the screw is often visible on the outer housing of these products, the appearance of the head and surface matters as much as its function.
Solutions for plastics and mixed materials
The largest share consists of screws suitable for screwing into plastic. Here, an adapted point and thread geometry and the right material hardness are important, reducing the risk of thread damage or cracking of the plastic housing during assembly.
- screws for plastics
- standard screws to DIN and ISO
- special designs made to customer drawings
- adapted mechanical properties
- various surface coatings
Treatments and surface protection
The products often require additional treatments – heat treatment and electroplating with hydrogen embrittlement relief (de-embrittlement). Screws can be zinc plated in compliance with the RoHS directive, depending on project requirements.
Precision and quality control
- dimensional accuracy
- monitoring of mechanical properties
- batch traceability
- consistent quality at high production volumes
Stable European production
As a screw manufacturer in the EU, we provide technical support, flexibility and reliable delivery times. We work with OEM manufacturers and corporate development departments looking for a long-term partner for mechanical components.
Automotive industry
In the automotive industry, where requirements for safety, precision and reliability are exceptionally high, screws made by multi-stage cold forming dominate. This advanced production process enables series production of highly demanding fasteners with outstanding dimensional accuracy, mechanical properties and repeatability.
Our screws for the automotive industry are designed for installation in key vehicle components, where loads are high, tolerance deviations minimal and traceability requirements strictly defined. They are distinguished by premium material quality, closely controlled heat and surface treatments and geometry optimised for maximum functionality and a long service life.
In addition to technical excellence, we also provide logistical reliability, flexibility in batch sizes and adherence to delivery dates, which is crucial in the automotive supply chain.
If you are looking for a reliable partner to develop and produce technically demanding screws for the automotive industry, send us an inquiry – together we will develop a solution tailored to your specifications.
Heating, cooling and ventilation (HVAC)
Heat pumps, air conditioners, boilers, ventilation units and fans contain many sheet-metal housings, brackets and covers. The most common screws here are self-tapping sheet-metal screws and metric screws, often with a factory-assembled washer.
- self-tapping and self-drilling screws for thin sheet metal
- screws with washers for faster housing assembly
- surface protection adapted to moisture and condensation
- stable geometry for automated screwdriving
Sanitary ware and bathroom products
In sanitary ware, bathroom furniture, shower enclosures and accessories, screws are often exposed to moisture and cleaning agents and may also be visible. Corrosion resistance and the appearance of the head are therefore important.
- stainless steel versions (A2, A4)
- screws for plastics and composite materials
- even head finish for visible joints
Windows, doors and hardware
Windows, doors, blinds, roller shutters and the related hardware require screws that hold reliably in PVC, aluminium or wooden profiles and withstand constant loads when opening and closing.
- screws for PVC and aluminium profiles
- wood screws with optimised thread
- specific head shapes for hardware made to customer drawings
Lighting
Indoor and outdoor luminaires, LED modules and lighting housings need small screws with precise geometry, often for screwing into plastic or die-cast aluminium housings.
- small screws for plastic housings
- metric screws for aluminium parts
- RoHS-compliant surface treatments
Solar power and energy
Mounting systems for photovoltaic modules, distribution boxes, switchgear and electric vehicle charging equipment are exposed to the weather and require a long joint service life.
- stainless steel versions
- screws with washers for a stable joint
- corrosion-resistant surface coatings
Power tools and garden equipment
Drills, grinders, lawnmowers, trimmers and other tools are exposed to vibration, so the joint must retain its preload even under prolonged use. Housings are mostly plastic, while internal assemblies are metal.
- screws for plastics with a vibration-resistant thread
- metric screws in higher property classes
- drives suitable for automated assembly (TX)
Bicycles, e-bikes and sports equipment
The development of the sports industry and growing awareness of the importance of sport for health are driving ever newer and more demanding sports equipment. Because user safety is paramount, quality requirements for fasteners are also high. Screws for this field are most often made exclusively to the customer's drawings.
- screws in a higher dimensional class
- designs made to customer drawings
- batch traceability and control of mechanical properties
Mechanical engineering and automation
In the construction of machines, lines and automation components, metric screws in various property classes are mainly used to fix covers, sensors, guides and control cabinets.
- metric screws to DIN and ISO
- property classes up to 10.9
- various head and drive shapes
Shop fittings, shelving and office furniture
Shelving systems, shop shelves, office desks and chairs are often sold flat-packed, so the screws must be supplied in exact quantities and ready for quick assembly by the end user.
- screws for metal and wooden assemblies
- packing into bags and assembly kits
- screws with washers
Motorhomes and caravans
Motorhomes, caravans and vehicle bodies combine wood, composite panels, aluminium and plastic. Screws must therefore hold reliably in different materials and withstand vibration while driving.
- screws for composite and wooden panels
- self-tapping screws for thin sheet metal
- corrosion-resistant versions
