## Long description

Hex nut Niczuk M20 is a six-sided fastening nut designed for use with M20 metric bolts and threaded rods. Manufactured for mechanical and construction applications, it provides secure clamping and even load distribution in assemblies, machinery, scaffolding, and structural connections. The hexagonal shape allows for straightforward tightening with common wrenches and sockets, making it suitable for both repair and new-installation tasks where an M20 nut is specified.
Advantages
The Niczuk M20 hex nut delivers a consistent thread fit and reliable mechanical engagement with M20 bolts and studs. Its six-sided geometry facilitates efficient torque transfer and simple tool access in confined or exposed locations. Designed for use in typical industrial and construction environments, the nut offers predictable performance for standard fastening needs and straightforward replacement of worn or damaged fasteners.
Suitable for
Assembly of machinery and equipment using M20 fasteners
Structural connections and steel frameworks
Scaffolding, formwork, and construction joints
Maintenance, repair, and replacement of M20 nuts
Key specifications
Thread size: M20 (metric)
Shape: Hexagonal (6-sided)
Application: General mechanical and construction fastening
Compatibility: Designed to mate with M20 bolts and threaded rods
How to use
Select the appropriate M20 bolt or threaded rod and engage the nut by hand until it threads on smoothly. Use a properly sized wrench or socket to tighten to the required torque for your application, taking care to follow any project- or manufacturer-specific torque specifications. For disassembly, reverse the process by applying the wrench or socket in the opposite direction and unthreading the nut. Ensure alignment of mating threads to avoid cross-threading during installation.
Usage recommendations
Use appropriate torque values and, where specified, complementary washers or locking devices for improved vibration resistance. Inspect thread condition before reuse and replace the nut if threads are damaged, corroded, or show significant wear. Store fasteners in a dry environment to reduce corrosion risk.
