Metric All Metal Hex Nut

The metric all metal hex nut uses a deformed thread or cone design, which creates friction to prevent loosening. Materials such as Grade 8 steel or A4 stainless steel are rust resistant and can withstand high torque. The hexagonal shape can be used with standard metric tools.  

Product details and parameters

The metric all metal hex nut is a heavy-duty fastener made entirely of metal (like steel or stainless steel) for use with metric-sized bolts. Its hexagonal shape fits standard wrenches, and the all-metal build handles high heat, heavy loads, or corrosive environments where plastic parts fail.

Why choose the metric all metal hex nut?

The metric all metal hex nut is built tough. The all-metal design withstands extreme temperatures (like exhaust systems) and harsh chemicals. No nylon inserts to melt or wear out,just torque it down, and it stays put. Reusable multiple times if undamaged, and works in oily or greasy conditions where other nuts slip.

Metric all metal hex nut is commonly used in automotive manufacturing (engine blocks, turbochargers), heavy machinery (cranes, presses) and oil/gas equipment (pipes, valves). Factories use it to make high-temperature ovens, and aerospace uses it to make heat-resistant panels. It can be used in places where plastic locks don't work.

Why It Beats Plastic Locks

Unlike nylon-insert nuts, the metric all metal hex nut won’t melt in high heat or degrade in chemicals.  It costs more upfront, but can save money in the long run by reducing the number of replacements. It's an obvious material for heavy machinery, engines, or outdoor construction,metal is more durable where plastic fails.
