Overview


JZ7 Cronimaks Self-Tapping Screws

EJOT Cronimaks® JZ7

  • Self-tapping screws manufactured from austenitic high-grade stainless steel.

  • For fixing profiled steel sheets / sandwich elements onto steel substructures up to S355 (St 52) and stainless steel substructures (up to Rm = 700 N/mm²).

  • Approved A2 stainless steel screw for high-strength steel substructures.

  • Pre-assembled stainless steel sealing washer.

  • Hexagon A/F 3/8" drive.

Through metallurgical expertise and special manufacturing technology, EJOT has achieved a hardness to the threads' edges, which provides superior performance over and above any other product on the market.

Conventional fasteners tapped into steel plate with tensile strengths ≥ 500 N/mm2 are prone to crushing/malformation of the thread edges.

Corresponding threads are not adequately formed. Effective clamping of metal section to this material is not possible.

Self-tapping EJOT Cronimaks® JZ7 fasteners enable thread forming into structural steels with tensile strengths up to Rm=700 N/mm².

Efficient fixing into high-grade steel sheet is up to Rm=700 N/mm² equally possible.
