Introduction to other fasteners

Other fastening elements encompass a wide variety of components used to secure, position and join different parts in structures and construction systems. Beyond common items like screws and nails, this category includes specialized devices that provide stability, strength and adaptability in specific applications.

These elements play a crucial role in the structural integrity and functionality of buildings, machinery and furniture, being selected according to the technical needs, materials involved and environmental conditions. Its correct choice and use contribute to guaranteeing the durability and safety of constructions.

Special washers

Washers are circular components that are placed between the head of a fastener and the surface being joined, to distribute the load and protect materials. Within the special washers are the concave housing washers, designed to adapt to spherical surfaces and compensate for irregularities, improving positioning and adjustment.

These washers allow the screws or bolts to maintain uniform contact with the part, avoiding localized stresses that could cause failure or deformation. Its use is common in assemblies where precision and stability are critical, such as in metallic or mechanical structures.

In addition, there are washers with different surface treatments and materials, adapting to corrosive environments or high loads, which expands their range of application in construction and industry.

Pins and cotter pins

Pins are cylindrical elements that are used to ensure the relative position of two or more pieces, preventing unwanted movements. They are commonly used in removable mechanisms and joints where quick and safe assembly is required.

Cotter pins, for their part, are pieces that are inserted into slots of axles and gear wheels or pulleys to transmit movement and prevent slipping. They are vital in mechanical transmission systems and in the fixation of rotating components.
