Our GEVAG Proprietary Brands
The screws of our established brands GEVAG KUNST and GEVAG TAP enable efficient and reliable direct fastening. The proven GEVAG KUNST screw is developed and optimized for direct fastening in thermoplastics. As a high-performance thread-forming screw, GEVAG TAP offers quick and secure connection assembly for steel as well as light and non-ferrous metals. The advantage: Thanks to the thread-forming screw, work steps and costs associated with otherwise necessary thread cutting, thread cleaning, and the tools required for these processes are eliminated.
GEVAG KUNST – Screws that self-form the thread for secure fastening in thermoplastics.
The proven screws of the brand GEVAG KUNST have been specially developed for self-forming fastening in thermoplastics and have been reliably used for direct fastening for many years. Unlike self-tapping screws, which cut the thread into the material, self-forming screws utilize the ductility of thermoplastics, forming them without chips and solidifying them in the process. The result: a particularly secure screw connection.
These special products are screwed into molded or drilled core holes, requiring only a relatively low insertion torque. Structurally, our KUNST brand screws are characterized by a large thread pitch, small core diameters, and a flank angle of 30°. This ensures optimal fastening with high pull-out strength and without material damage. The small core diameter prevents cracking or bulging during use.
Advantages of GEVAG KUNST
- Small radial forces – low radial expansion
- Low insertion torque
- Enormous load capacity due to high thread load-bearing capability
- No material damage
- Individually configurable in many different head shapes and thread diameters (1.8 – 6 mm)
Application in various industrial sectors
- Household appliances
- Medical technology
- Energy sector
- Automotive
GEVAG TAP – self-tapping screws for secure connection of steel, light and non-ferrous metals
Our thread-forming screws according to DIN 7500 of the brand GEVAG TAP form metric threads in steel as well as light and non-ferrous metals. Their trilobular thread design enables screwing into a drilled or punched hole without pre-cutting a mating thread. Due to their thread-forming properties, a metric ISO mating thread is created without chips during insertion and with relatively low effort due to the low insertion torque. This saves work processes and also ensures a backlash-free thread, thus providing excellent power transmission between the screw and the component material. The mating thread in the component is shaped to accommodate a standard screw, offering optimal compatibility. GEVAG TAP is available with many head shapes, drive types, and thread diameters (M2 – M6) and is individually configurable.
Advantages of GEVAG TAP
- No separate thread cutting necessary
- Cost savings of up to 30% compared to screws requiring a tapped hole
- The formed thread is metric, allowing a standard screw with an ISO thread to be used
- No chips during the screwing process
- Screwing with low effort due to low forming torque
Application in various industrial sectors
- Automotive
- Mechanical and plant engineering
- Household appliances
GEVAG PLAST – Screws for secure connection of plastics and light metals
Our screws for secure connection of steel, light and non-ferrous metals of the brand GEVAG PLAST offer enormous advantages due to their special design properties. High processing quality and sophisticated technology guarantee a high degree of user-friendliness.
The specific properties are: large thread pitches, small core diameters, trilobular thread cross-sections.
Advantages of GEVAG PLAST
- Good resistance against vibrational loosening
- High pull-out and extraction strength
- Low insertion torque
- Reduced risk of cracking
- Small core diameters
Application in various industrial sectors
- Household appliances
- Medical technology
- Energy sector
- Automotive
GEVAG KSG – Screws with plastic saw-tooth thread
The GEVAG KSG screws with plastic saw-tooth thread are suitable for direct fastening in light metals and high-strength plastics and have been reliably used for many years. The special asymmetrical thread design (saw-tooth like) serves to absorb the forces generated during fastening.
These special products are screwed into molded or drilled core holes, requiring only a relatively low insertion torque. Structurally, our screws with KSG thread are characterized by their special asymmetrical thread design, low pitch, and a flank angle of 27°. This ensures optimal fastening in high-strength plastics with high pull-out strength. The special thread design prevents cracking during use.
Advantages of GEVAG KSG
- Low insertion torque
- Very good assembly properties for direct fastenings
- Enormous load capacity due to high thread load-bearing capability (thread parameters: P, d1...)
- Individually configurable in many different head shapes and thread diameters
- Optionally available with scraping slot (DIN 4753)
Application in various industrial sectors
- Household appliances
- Mechanical engineering
- Medical technology
- Energy & Electronics sector
