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.

Low-Profile Precision Shoulder Screws
The head height of these screws is about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines. Made of 18-8 stainless steel, they have good corrosion resistance and may be mildly magnetic. With a shoulder diameter that is twice as precise as our general purpose shoulder screws, they provide smooth, accurate movement. Use them where precision matters, such as in measuring devices, optical fixtures, and laboratory equipment.
TiCN-coated stainless steel screws have a layer of titanium carbonitride to reduce friction and allow rotating and sliding components to move smoothly across their length.
