JCP ETA Ankerbolts, Hexagon Flange Head, A4 Stainless
We supply JCP ETA hexagon flange head Ankerbolts in A4-316 stainless steel from 6mm to 12mm drill size, lengths 50mm to 150mm. The bi-metallic design pairs a stainless body with a carbon-steel tip whose leading threads cut into the concrete - marine-grade corrosion resistance without losing the self-tapping action. Some sizes sit outside the ETA and are noted. The self-tapping screwbolt principle is unchanged: expansion-free and removable.
Also known as: stainless ankerbolt, a4 screwbolt, bi-metal ankerbolt.

Related specificationsWhy is the A4 Ankerbolt bi-metallic?
Stainless steel will not reliably cut threads in concrete, so JCP fit a hardened carbon-steel tip whose leading threads do the cutting while the A4 body carries the fixing and resists corrosion. The tip sits buried at the bottom of the hole once installed.
