Titanium Socket Head Screws
Fully Threaded
Partially Threaded
Our most corrosion-resistant metal screws, titanium screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio and are about 40% lighter than steel screws. All meet either ASME B18.3 or ISO 4762 (formerly DIN 912) dimensional specifications. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

Titanium Shoulder Screws
Titanium shoulder screws have a high strength-to-weight ratio and are more resistant to acids and salt water than nickel shoulder screws. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components, and as an axle or pivot point.
