In bolted connections, details are paramount. Even the best bolt can pose problems during assembly and disassembly if its surface isn't properly protected. That's why GLEITMO-coated fasteners are increasingly being used – a solution that truly improves the performance of bolts, nuts, and washers. Reduced friction, improved surface protection, and easier connection management make GLEITMO not just an accessory, but a crucial element of reliable assembly.
GLEITMO – what do screws and fasteners gain from this coating?
When it comes to bolted connections, it's not just the strength class or thread geometry that matters, but also the surface condition of the fasteners. Increasingly, bolts, nuts, and washers are being factory-coated with special coatings that improve their assembly and operational properties. One of the most effective solutions in this regard is the GLEITMO coating, available from Eurobolt.
What is the GLEITMO coating on fasteners?
GLEITMO is dry lubricating filmwhich is applied to screws, nuts and other fasteners in order to reducing friction and protecting the metal surfaceOnce applied, it creates a thin, uniform layer that permanently bonds to the surface of the element, leaving no greasy film or stickiness.
This means that GLEITMO-coated screws behave differently than uncoated elements – both during assembly and subsequent use.
Below are the advantages of using GLEITMO coated elements.
Reduced friction – easier tightening and loosening
One of the most important advantages of GLEITMO coated screws is significant reduction of the friction coefficient on the thread and under the screw headIn practice, this means:
- smoother tightening,
- less resistance during assembly,
- easier and safer unscrewing, even after long periods of use.
Lower friction also makes tightening torque more predictable and the clamping force is distributed evenly throughout the connection. This is particularly important in structural connections and during series assembly.
Greater resistance to scorching and cold welding
In the case of stainless steel screws or components subjected to high pressure, thread seizure (cold welding) can occur. The GLEITMO coating effectively reduces direct metal-to-metal contact, allowing:
- reduces the risk of thread damage,
- protects the bolt and nut against seizure,
- enables subsequent disassembly without destroying the connection.
This makes GLEITMO-coated fasteners much safer to install and service.
Additional anti-corrosion protection
While GLEITMO's primary function is lubrication, this coating also provides an additional protective barrier for the screw surface. Coated components include:
- less susceptible to the effects of moisture,
- better protected against oxidation,
- more resistant to aggressive working environments.
Clean and durable coating – ideal for serial installation
GLEITMO is a dry coating, which means that:
- does not dirty hands or tools,
- does not collect dust and dirt,
- does not change its properties during storage.
This makes GLEITMO-coated screws ideal for automatic assembly, production lines and prefabrication, where repeatability of parameters and process cleanliness are crucial.
Where are GLEITMO coated screws and fasteners used?
GLEITMO-coated elements are used wherever controlled friction, connection durability and the possibility of trouble-free disassembly are important, including:
- steel structures,
- machinery industry,
- automotive,
- industrial installations,
- connections exposed to high loads and temperatures.
