High tensile bolts in grades 8.8, 10.9 and 12.9 for steel construction and building connections, M4–M30, 6mm to 300mm.
What this group is for
High tensile bolts are the one place in this catalogue where a higher number is not automatically a better answer. Strength comes at the cost of ductility and brings a hydrogen embrittlement risk into any electroplating step, so the grade and the finish have to be decided together.
- Grades 8.8, 10.9 and 12.9
- M4–M30, lengths 6mm–300mm
- Specified for steel construction and building bolts
