DIN 6923 M6 Titanium Nut — High-Strength Flange Fastener for Lightweight Engineering

The DIN 6923 M6 titanium nut is a precision hexagon flange nut manufactured from Ti-6Al-4V (Grade 5) alloy, combining M6 × 1.0mm pitch threading with an integrated load-distributing flange. It delivers tensile strength exceeding 895 MPa at a density of just 4.43 g/cm³ — approximately 45% lighter than equivalent steel fasteners. Backed by Baoji Huacan's 10+ years of titanium machining experience, 40+ CNC machines, and ISO 9001 certification, this nut is engineered for motorsports, aerospace, UAV, and marine environments.

Why Choose Our DIN 6923 M6 Titanium Nut for Your Application

Baoji Huacan supplies titanium flange nuts built to perform where standard fasteners fail. The integrated flange eliminates the need for a separate washer, reducing assembly time and part count — a real advantage on production lines.

The serrated flange face creates a natural locking action under vibration. This is critical in motorsports and UAV applications where fastener loosening causes operational risk.

Ti-6Al-4V resists chloride corrosion, saltwater, and acidic media, outperforming 316 stainless steel. It also stays non-magnetic, protecting sensitive electronic environments from interference.

Motorsports & Cycling: Used on sprocket carriers, exhaust manifold studs, and frame components. The flange protects aluminum surfaces from gouging, and titanium handles exhaust thermal cycling without seizing.

Aerospace & UAV: M6 is a standard structural fastener size for FPV drone frames and commercial UAV assemblies. Weight reduction directly extends flight time, while the flange maintains connection integrity under motor vibration.

Marine & Chemical Processing: Offshore rigging and chemical valve assemblies rely on titanium's immunity to pitting and crevice corrosion in seawater and acidic environments — especially where maintenance access is difficult.

Marine Equipment

Precision Equipment

· Integrated flange design — distributes clamping load over a wider bearing surface, protecting soft substrates like aluminum and carbon fiber

· Serrated or smooth flange — serrated face prevents loosening under vibration; smooth face prevents abrasion on delicate surfaces

· ~45% weight saving vs. equivalent steel nuts at comparable strength

· Non-magnetic — safe for electronics-sensitive assemblies

· Anti-galling options — PVD coating or DLC coating available to reduce friction and prevent titanium cold-welding

· Corrosion immunity — resistant to chlorides, seawater, and acidic media

Material Features

Baoji Huacan operates 40+ CNC lathes, machining centers, and gantry systems in Baoji — China's recognized titanium manufacturing hub. Annual production capacity exceeds 1,000 tons of finished components.

Forging capability backed by a 4,000-ton hydraulic press ensures reliable raw material quality upstream. Melting capacity exceeds 5,000 tons annually using VAR and plasma arc furnaces.

This vertical integration — from ingot to finished fastener — means tighter process control and faster delivery on custom orders.

Production begins with verified Ti-6Al-4V bar stock, checked by XRF spectrometry for composition accuracy. Precision CNC turning ensures thread profiles meet 6H tolerance class consistently.

Thread machining is performed using calibrated tooling monitored throughout each production run. Go/No-Go gauge checks are applied to every batch, not just samples.

Post-machining, parts undergo surface treatment — polishing or anodizing — per your specification. OEM and drawing-based production is fully supported for custom geometry.

· In-process dimensional monitoring — tolerances checked at each production stage

· Go/No-Go thread gauging — 100% thread inspection for 6H compliance

· Coordinate Measuring Machine (CMM) — final dimensional verification

Q: How do I prevent galling when installing titanium nuts?

A：Apply an anti-seize compound before installation. PVD or DLC coating on the nut also reduces friction significantly. Never install dry under load.

Q: Can this nut replace Grade 8.8 steel in my assembly?

A：Yes. Ti-6Al-4V offers comparable strength to Grade 8.8 steel with substantial weight savings and far superior corrosion resistance.

Q: What torque should I use for M6 Ti-6Al-4V nuts?

A：Typically 9–12 Nm dry. Reduce by 20–30% when anti-seize paste is applied to avoid over-stretching the bolt.

Q: Is the serrated flange always required?

A：No. Smooth flange versions are available — recommended when fastening onto carbon fiber or delicate anodized surfaces.

Q: Will titanium cause galvanic corrosion on aluminum?

A：In saltwater environments, titanium is noble and can cause aluminum to corrode sacrificially. Use dielectric grease or insulating washers in mixed-metal assemblies.

Q: Is the product available in custom sizes?

A：Absolutely. All dimensions, thread specs, and structural features are customizable based on your drawings or requirements.
