1. General Introduction

We carry a large range of titanium hexagon head bolts in stock. They are manufactured to ISO 4014 and its equivalent standard DIN 931. Generally, the material covers titanium grade 1 (UNS N50250), grade 2 (UNS N50400), grade 5 (R56400) and grade 7 (R52400).

The titanium hexagon head bolts are available in two product grades: product grade A for threads M1.6 to M24 and nominal lengths up to and including 10d or 150 mm, whichever is shorter; and product grade B for threads over M24 or nominal lengths over 10d or 150 mm, whichever is shorter.
