Metric Hex Tap Bolt, Class 10.9, Zinc Plated Steel, M20 x 2.5 x 90M

Diameter - Thread Pitch: M20-2.5
  • Hex head for standard wrench or socket installation
  • Class 10.9 high-strength steel – approximately 1,040 MPa tensile strength
  • Known as a hex cap screw or tap bolt, these are fully threaded
  • Zinc plated finish – RoHS compliant corrosion protection
  • M20 x 2.5mm coarse thread pitch – multiple lengths available

This M20 x 2.5mm hex tap bolt is manufactured from Class 10.9 high-strength steel with a zinc plated finish for reliable corrosion resistance in indoor and sheltered outdoor applications.  Class 10.9 steel delivers approximately 1,040 MPa tensile strength, making these fasteners suitable for heavy-duty structural connections, machinery assembly, and high-load applications where standard Class 8.8 bolts are insufficient. The zinc plating adds a protective barrier against moisture and mild environmental exposure while maintaining RoHS compliance.

A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread

Product number: MHBZP1092090
