Parameters to Confirm When Sourcing Titanium Screws

The Short Answer

To source titanium screws, confirm: thread specification (diameter and pitch), length, head type and drive type, material grade, applicable standard, quantity, and destination. "M6 titanium screw" is not a specification — it becomes one only when all of the above are stated.

Titanium fasteners are chosen for their strength-to-weight ratio and corrosion resistance, and they cost significantly more than steel equivalents. Clear parameters prevent paying titanium prices for the wrong part.

Thread Specification and Dimensions

State the thread diameter and pitch explicitly — for metric threads, the nominal diameter and pitch; for inch threads, the diameter and thread count per inch. State the length and how it is measured, because length conventions differ between head types: some are measured under the head, others overall.

Head type (hex, socket, button, countersunk, and others) and drive type (hex socket, Torx-style, slotted, and others) both matter for function and tooling. If the screw must match an existing assembly, name the head and drive exactly or provide a photo.

• Thread diameter and pitch (metric) or thread count (inch).
• Length and its measurement convention for the head type.
• Head type and drive type, stated exactly.

Material Grade

Titanium fasteners are commonly specified by grade designations — commercially pure grades where corrosion resistance and formability dominate, and alloyed grades such as Ti-6Al-4V where higher strength is required. The grade determines strength, weight of evidence on certificates, and price, so it belongs in the inquiry.

If you are unsure which grade your application needs, describe the application: load, environment, and why titanium rather than steel. A sourcing partner can coordinate a grade recommendation from the supply side, with the final specification confirmed per order.

Standards, Finish, and Quantity

Reference the applicable product standard where one exists — international and national standards define dimensions, tolerances, and mechanical requirements for common screw types. For non-standard screws, a drawing replaces the standard reference.

State surface requirements: plain, polished, anodized, or coated. Quantity matters more than usual for titanium because raw material and machining costs are both high — small batches are possible, but price per piece drops meaningfully with volume. Destination and required delivery date complete the inquiry.

What Is Confirmed Per Order

Grade availability, applicable certificates, price, minimum order quantity, and lead time are confirmed per order. Where the supplying factory can provide material certificates, a sourcing partner can coordinate them with the order — agree the document types before production.

For safety-relevant applications, specify the documentation requirement at the inquiry stage so it is priced and planned into the order rather than requested afterward.
