Acceptance is by the ordered specification. Final dimensions, tolerances, grade, inspection and documentation are confirmed by the drawing, purchase order and mill test certificate.
Titanium Bolts, Nuts, Screws and Custom Fasteners
Beiyu supplies titanium fasteners for aerospace-related assemblies, marine hardware, medical equipment, chemical equipment, cycling components, industrial fixtures and custom machined parts. Common products include titanium bolts, hex nuts, washers, screws, threaded rods, studs and drawing-based fasteners.
Grade 2 titanium fasteners are commonly used where corrosion resistance and moderate strength are required. Grade 5 / Ti-6Al-4V is selected where higher strength-to-weight ratio is needed. Grade 7 and Grade 12 may be reviewed for chemical or marine environments where corrosion behavior is more important than standard mechanical strength classes.
Grades and Standards
| Common grades | Grade 2, Grade 5 / Ti-6Al-4V, Grade 7, Grade 12. |
|---|---|
| Material references | ASTM B348 bar material, ASTM F67 / ASTM F136 for medical-related titanium where applicable, and project-specific fastener standards. |
| Thread standards | Metric, UNC, UNF or drawing-based thread requirements. |
| Product forms | Bolts, screws, nuts, washers, studs, threaded rods and custom machined fasteners. |
Size Range and Surface Finish
Fastener RFQs should specify thread standard, nominal diameter, length, head type, drive type, tolerance, grade, quantity and surface condition. Common head styles include hex head, socket head, countersunk head, button head and custom machined head forms according to drawings.
Surface finish may include machined, polished, pickled, passivated or anodized surface depending on application. For fasteners used in chemical, marine or medical-related assemblies, buyers should confirm cleanliness, burr control, thread quality and whether galling prevention or lubricant requirements must be considered.

FAQ
Which titanium grade is used for high-strength fasteners?
Grade 5 / Ti-6Al-4V is commonly used when higher strength-to-weight ratio is required. Grade 2 is more common for corrosion-resistant fasteners where moderate strength is acceptable.
Can titanium fasteners be anodized?
Anodized surface can be specified for color identification or appearance requirements. Buyers should confirm color, surface preparation, batch consistency and whether the fastener will be used in a decorative or functional assembly.
What information is needed for custom titanium screws?
Send a drawing or sample information with grade, thread type, diameter, length, head type, drive type, tolerance, surface finish, quantity and certificate requirements.
Related Bar Material and Fastener RFQ Pages
For custom titanium bolts, screws, nuts and washers, buyers often specify the upstream bar material together with the finished fastener drawing. Review the titanium bar hub, Grade 2 titanium bar, Grade 5 Ti-6Al-4V titanium bar, the ASTM B348 bar guide and the titanium grades comparison guide before confirming thread, diameter, length, head type, quantity and MTC requirements.

Specification detail with sources
Titanium fastener stock starts as bar, and the bar definition is dimensional rather than descriptive. ASTM B348 separates bar from billet by cross-sectional area, placing the boundary at 16 square inches, 10,323 square millimetres, and it further limits rectangular bar to a width not exceeding 254 millimetres with a thickness above 4.8 millimetres (ASTM B348, bar and billet definitions). Fastener diameters sit far below that boundary, which is why the classification question on a fastener enquiry is about the finished part rather than about the stock it is machined from.
The composition limits behind a fastener certificate are heat analysis limits taken at the melt. For Grade 2 the oxygen limit is 0.25 percent maximum with iron at 0.30 percent maximum, and for Grade 5 the aluminium range is 5.5 to 6.75 percent with vanadium at 3.5 to 4.5 percent (ASTM B348, chemical requirements). Those figures are produced by named methods rather than by a general practice: ASTM B348 references ASTM E1409 for oxygen and nitrogen, ASTM E1447 for hydrogen and ASTM E1941 for carbon, with rounding to ASTM E29 before any value is compared to a limit (ASTM B348, referenced documents and test methods). Naming a method settles how a value was produced. It does not add an examination the order did not ask for. Beiyu Titanium supplies fasteners with an EN 10204 3.1 mill test certificate carrying heat number traceability, with the reporting scope set by the order.
Size range and materials for titanium fasteners
A fastener enquiry is settled by three lines rather than one: the thread size, the material with its grade, and the standard the head and thread geometry follow. The size band also decides which materials are available, which is the part most often assumed.
| Thread size | Materials supplied at this size |
|---|---|
| M0.3 to M3 | Titanium Grade 2, Grade 7 and Grade 12 |
| M3 to M64 | Titanium Grade 2, Grade 5, Grade 7 and Grade 12; zirconium 702; tantalum; niobium; nickel and nickel alloys |
Bolts, screws, nuts and washers are produced across that range by turning, pressing and milling, on CNC lathes, milling machines and cold heading presses. The route for a given part is confirmed at quotation against the drawing, so a drawing carries further than a description.
Head and thread geometry is quoted against DIN, JIS or GB as the order names, and the material is a separate line again: a fastener made from Grade 5 to a DIN head form is two specifications on one part, and the certificate reports against the material one. The ranges above are the Beiyu Titanium supply envelope; sizes and head forms outside them are quoted against the drawing.
