Description
Titanium Gr2 Bolt DIN912 is a hex socket head bolt made from commercially pure titanium (Grade 2), known for its excellent corrosion resistance, light weight, and high
strength-to-weight ratio. Designed according to the DIN912 standard, this fastener provides a secure and precise connection in
demanding environments.
Titanium Gr2 bolts are widely used in aerospace, automotive, marine, and cycling industries, where performance, durability, and reduced weight are critical.
Compared with traditional steel bolts, Titanium Gr2 fasteners offer
superior resistance to oxidation and chemicals, making them an ideal choice for harsh and corrosive conditions.
Although titanium fasteners are typically more expensive than steel
ones, their long service life, low maintenance requirements, and
performance advantages make them a cost-effective solution for advanced engineering applications.
