Hex Head Bolts — DIN 933 / ISO 4017
Fully threaded hex bolts in property classes 8.8 to 12.9, cold- or hot-forged and heat treated in house.
SpecificationsSleeve anchors give a predictable, inspectable fixing in base material where chemical anchoring is impractical. We form the sleeve, machine the mandrel and assemble in house, which keeps the expansion tolerance consistent batch to batch — the usual cause of pull-out variance in imported anchors.
