Our products
Threaded plugs ensure a reliable, leak-proof seal for liquid applications.
We offer a wide range of models in different materials — plain or zinc-plated steel, stainless steel (A2 and A4), and brass.
Dowel pins are mechanical connectors used to join two components.
Different types of pins are available depending on the assembly requirements.
The main options include hardened or non-hardened cylindrical pins, as well as stainless steel pins (A1 or A4).
Precision-ground shank screws consist of a ground shank with a knurled cylindrical head and a threaded portion.
Ground screws are used in equipment subjected to compressive or tensile loads. They replace expensive special components such as shafts, dowel pins, and guides. They are also used as shafts or pins for pulleys, gears, cams, etc., or as stationary guides for moving parts in molds and various machinery.
Inch fasteners refer to various types of screws and bolts measured in inches.
Available options include UNC (Unified National Coarse) and UNF (Unified National Fine) screws.
Also available are standard and self-locking nuts according to ASME.
Set screws are headless screws with two ends, fully threaded into a tapped hole.
Set screws come with various tip types, including standard, conical, cylindrical, oval cup, and knurled cup.
They can also be blackened, zinc-plated, or finished with other surface treatments.
Clamps are used to tighten hoses, sleeves, and tubular elements made of deformable materials to create a secure fit with a rigid connection.
Metal clamps are employed when it is necessary to ensure that a rubber hose—or other elastic material—adheres firmly and safely to another cylindrical component.
UBK is an authorized distributor of the MIKALOR brand.
Rings are used to secure components, maintain alignment, or provide support in mechanical assemblies. They can serve as retaining elements, spacers, or safety stops depending on the application. Our range includes various types and sizes to meet industrial requirements.
Inserts are mechanical components designed to reinforce threads in soft materials or to repair damaged threads. Available in different materials and finishes, they ensure durable and reliable connections in a wide range of applications.
Connectors are used to join or link mechanical components, pipes, or electrical elements. They provide a secure, stable, and precise connection to ensure optimal performance in industrial systems.
