JCP ETA Option 1 Throughbolts, Bright Zinc Plated

M8 - M20 (75 - 195mm) Carbon steel, bright zinc plated

We supply JCP ETA Option 1 throughbolts in bright zinc plated steel from M8 to M20, lengths 75mm to 195mm. Option 1 is the European Technical Assessment for cracked as well as non-cracked concrete, and JCP list this range with fire resistance loading and seismic C1 and C2 within the assessment scope. Each size carries both a standard and a shallow embedment listing, so the same anchor can be set at reduced depth where the slab dictates.

Also known as: eta throughbolt, option 1 throughbolt, cracked concrete anchor, seismic throughbolt.
