Calculate the exact weight of your extreme-environment fasteners instantly. Our All-Metal Hex Lock Nut Weight Calculator is designed specifically for prevailing torque type hex nuts featuring a captive metal insert (DIN 980 M standard).
Whether for automotive exhaust systems, heavy-duty engines, or high-temperature machinery, precision matters. Unlike nylon-insert nuts, these all-metal lock nuts utilize a spring steel clip to withstand extreme heat while providing exceptional vibration resistance. Get accurate weight data in seconds.
Supported Size Range:
- ✔ Diameters: M3, M4, M5, M6, M8, M10, M12, M16, M20, M24, M30, M36, up to M39.
- ✔ Material: All-Metal Construction (Polymer-free and heat-resistant, perfect for high-temperature environments).
- ✔ Key Feature: Built-in Metal Insert (A captive spring clip grips the bolt threads to prevent loosening under vibration).
