Zoro Select M04190.160.0001 Hex Nut M16-2.00 Class 12 Steel Black Oxide 13mm

SKU CH-V4VC-ES0QY

A Class 12 steel hex nut with M16×2.00 thread, 24 mm hex width and 13 mm height, finished in black oxide to DIN 934

  • Product typeNuts
  • Class 12 steel delivers high tensile strength for demanding assemblies
  • M16 x 2.00 metric thread ensures precise fit with matching bolts
  • 24 mm hex width allows secure tightening with standard wrenches
  • 13 mm hex height provides low-profile installation in tight spaces
  • Black oxide finish adds corrosion resistance for longer service life

Application & User

This M16-2.00 Class 12 steel hex nut suits maintenance crews and assembly lines that need a high-strength metric fastener. The black oxide finish adds mild corrosion resistance for indoor or sheltered outdoor use. It is not for builders who need a locking feature or a larger thread diameter.

Sustained Load Behaviour

Class 12 rating means the nut maintains clamping force under continuous vibration and thermal cycling without permanent deformation. The right-hand thread and DIN 934 geometry distribute stress evenly across engaged threads. REACH compliance confirms the material meets restricted-substance limits for long-term service.

Deciding Specification

The 24 mm hex width dictates the spanner or socket size required for installation and removal. A 13 mm hex height sets the minimum thread engagement and stack-up clearance. Verify both dimensions against your tool access and joint design before ordering.

Questions about this item

Does the Class 12 steel hex nut generate heat or noise during continuous fastening?

No, the M16-2.00 Class 12 steel hex nut is a passive fastener with no moving parts, so it produces no heat or noise once installed.

What tools must I already own to install this M16-2.00 hex nut?

You need a 24 mm wrench or socket to match the hex width, plus a compatible M16-2.00 bolt or threaded rod.

Will this DIN 934 Class 12 nut work with older Grade 8 bolts I have in stock?

Yes, the M16-2.00 thread pitch matches standard metric coarse threads, so it fits existing M16 bolts, but the Class 12 rating exceeds Grade 8 strength.
