Écrou plat Harting 21 01 000 0018

The Harting 21 01 000 0018 flat nut is a stainless steel fastening component designed for M16 applications. Lightweight and corrosion-resistant, the nut provides a stable threaded connection where space is limited or a low-profile finish is required. Its compact form factor and stainless steel construction make it suitable for use in mechanical assemblies, electrical housings, and environments exposed to moisture or mild chemicals.

Advantages

This flat nut combines stainless steel durability with a low-profile design that minimizes protrusion while maintaining secure thread engagement. Its light weight contributes to overall assembly efficiency, and the material resists rust and surface degradation under normal operating conditions. The standard M16 thread size allows compatibility with common bolts and studs used across industrial and construction applications.

Suitable for

• Securing components in confined or low-clearance assemblies
• Fastening in electrical enclosures and panels
• General mechanical fastening where M16 threads are specified
• Applications requiring corrosion resistance and a discreet finish

Key specifications

• Material: stainless steel
• Thread size: M16
• Weight: approximately 2.7 g
• Form factor: flat / low-profile nut

How to use

Fit the nut onto a matching M16 bolt or stud and tighten to the torque appropriate for the bolt grade and application. Ensure mating threads are clean and free of debris before assembly to prevent cross-threading. For installations where vibration is present, consider using complementary locking devices or threadlocker according to the assembly requirements.

Recommendations

Use in environments within the stainless steel corrosion resistance limits; avoid prolonged exposure to highly aggressive chemicals or chloride-rich atmospheres without additional protective measures. Select the correct bolt grade and apply recommended torque values to ensure reliable fastening and avoid thread or component damage.
