Induction Hardening

Specialist machinery for induction hardening fastener threads either through hardening, or zone hardening leaving the cores of the heat treated fastener unaffected. This gives thread forming screws the ability to retain core toughness, but with hard threads to meet the most punishing applications of thread forming screws.

Specialised zone heat treatment provides:

• wear resistant areas
• thread forming features


Our range of metal finishes and pre-applied lubricants can be applied to hardened screws to provide in-place corrosion resistance and controlled installation and prevailing torques.

An induction hardening facility for fasteners ranging from M5-M12 is also available.
