Description
Titanium slotted head bolts are strong, lightweight, and
corrosion-resistant fasteners suitable for demanding applications.
They are widely used in aerospace and automotive industries where
both strength and weight reduction are critical.
Additionally, titanium slotted head screws are commonly utilised in
marine, medical, and industrial equipment due to their superior
corrosion resistance and biocompatibility.
These bolts are available in a variety of standards, grades, sizes,
and colours to meet diverse engineering requirements.
Standards
DIN 963 – Titanium Slotted Countersunk Head Bolt
DIN 85 – Titanium Slotted Pan Head Bolt
DIN 84 – Titanium Slotted Cheese Head Bolt

Advantages
High Specific Strength
With a density of only 4.51 g/cm³, titanium is lighter than steel
yet significantly stronger.
Excellent Corrosion Resistance
Titanium and its alloys perform exceptionally well in a wide
variety of corrosive environments, including seawater and chemical
media.
Outstanding Heat and Low-Temperature Resistance
Titanium slotted head bolts maintain their performance from −250 °C
to 600 °C without deformation.
Non-Magnetic and Non-Toxic
Titanium is non-magnetic and biocompatible, making it ideal for
medical and electronic applications.
Superior Damping Properties
Titanium’s long vibration attenuation makes it suitable for
acoustic, ultrasonic, and precision applications.
Applications
Aerospace and automotive fasteners
Marine engineering and shipbuilding
Chemical processing equipment
Medical implants and devices
Electronics and instrumentation
Industrial and architectural components
