The torque type all metal hexagon nuts are self-locking fasteners made entirely of metal—no nylon or plastic parts. Its hexagonal shape fits standard wrenches, and the "prevailing torque" design (like deformed threads or a tapered top) creates friction to resist loosening.  

Product details and parameters

The torque type all metal hexagon nuts built from materials like stainless steel or hardened alloys, it handles high heat, heavy loads, and harsh chemicals. Unlike nylon-insert nuts, it won’t melt or degrade in extreme conditions. Use it in engines, industrial gear, or anywhere vibrations or temperature swings are an issue.

Torque type all metal hexagon nuts use metal-to-metal friction to stay locked. The threads might be slightly crushed or angled to grip the bolt tighter as you tighten them. The hex shape ensures compatibility with standard tools, and the all-metal construction avoids plastic weaknesses. Torque type all metal hexagon nuts are often thinner than regular lock nuts, saving space in tight assemblies.

Downsides

Torque type all metal hexagon nuts can be harder to install due to the torque resistance, but that’s what keeps them secure.
