DIN912 M14 Titanium Bolt — Socket Cap Fastener for High-Performance Industrial Applications

The DIN912 M14 titanium bolt is a precision-engineered socket cap fastener manufactured from Ti-6Al-4V (Grade 5) alloy, delivering a minimum tensile strength of ≥895 MPa with a density of just 4.43 g/cm³ — roughly 45% lighter than equivalent alloy steel bolts. The M14 bolt is manufactured to DIN 912 / ISO 4762 with a thread pitch of 2.0mm and lengths of 30mm to 200mm. The surface treatments include burnt, polished, and anodised colour choices.

Why Choose Our DIN912 M14 Titanium Bolt

The appropriate fastener selection significantly affects system dependability, weight economy, and long-term maintenance costs. This is what makes our M14 titanium bolt unique:

You can count on material integrity. All bolts are produced from approved Ti-6Al-4V Grade 5 alloy, validated by XRF spectrographic examination prior to manufacturing. No substitutes, no cheating.

Lightweight, without sacrifice. The density is 4.43 g/cm3, compared with 7.85 g/cm3 for steel. Tensile strength is similar to Class 8.8 or 10.9 steel fasteners, but at almost half the weight. That’s important in aircraft, motorsport and marine constructions.

Natural corrosion resistance. Titanium instantly forms a passive TiO₂ oxide film on its surface. This makes it immune to chlorides, sulfides, and oxidizing acids — no coatings required for most harsh environments.

The non-magnetic performance. It is essential for MRI housings, delicate instruments and electronic assemblies where magnetic interference is not permitted.

Offshore & Subsea Engineering Titanium’s high-pressure saltwater corrosion resistance offers advantages for ROV housings, platform sensor arrays and subsea structural connections. cathodic protection is eliminated and replacement frequency is greatly reduced.

Motorsport and Performance Automotive: Fasteners for suspension wishbones, brake calliper mounts and chassis sub-frames need strong shear stress capacity and low unsprung mass. Ideal for performance engines and wheel hub assemblies The M14 size is an ideal fit.

Chemical Processing: Flange joints on heat exchangers and reactors processing chlorine or bleaching chemicals need materials that resist seizing and chemical attack. Titanium bolts avoid fastener failure in these situations from causing harmful spills.

Product Features

Baoji Huacan operates from China's "Titanium Valley" in Baoji, Shaanxi Province, with over 10 years of titanium machining experience. Our facility includes:

· 40+ CNC lathes and machining centers, including gantry systems

· 4,000-ton hydraulic press for precision forging

· Annual production capacity exceeding 1,000 tons of machined titanium parts

· Annual melting capacity exceeding 5,000 tons of titanium ingots (VAR and PAM furnaces via strategic partners)

· Support for prototype, small batch, and mass production

Each bolt begins with certified Ti-6Al-4V bar stock, inspected for chemical composition before entering production. The manufacturing sequence includes precision CNC turning, thread machining with Go/No-Go gauge verification, and head forming through cold or hot forging depending on dimensional requirements.

Over 40 CNC lathes and machining centers at our Baoji facility ensure tight dimensional tolerances are maintained throughout. Post-machining, each bolt undergoes deburring, surface treatment, and a final dimensional check using coordinate measuring machines (CMM) and digital gauges.

Thread quality is verified using 6g tolerance ring gauges, strictly complying with DIN 912 geometric requirements for head height, head diameter, and drive key dimensions.

Our multi-stage inspection process ensures every DIN912 M14 titanium bolt meets your exact specifications:

PMI Verification: XRF spectrographic analysis confirms Ti-6Al-4V elemental composition on incoming material. This eliminates the risk of lower-grade substitution.

Thread Inspection: Go/No-Go ring gauges at 6g tolerance verify every thread before shipment. Dimensional checks using CMM, micrometers, and height gauges ensure DIN 912 geometric compliance.

Mechanical Testing: Tensile and yield strength are tested on sample batches to confirm ≥895 MPa and ≥828 MPa minimum values respectively.

Surface & Defect Inspection: Fluorescent Dye Penetrant Inspection (DPI) identifies surface fractures or laps caused by thread rolling – important stress raisers that are not visible to the naked eye.

Final Documentation Each batch is delivered with material test certificates (MTC), inspection reports and complete traceability records of materials.

Q: How does galling affect titanium M14 bolts during installation?

A：Titanium has a greater coefficient of friction than steel and galling (cold welding) under torque is an issue. Always install using an anti-seize substance such as molybdenum disulphide (MoS2). Specify an anodised surface finish and you will also greatly decrease the possibility of galling.

Q: What torque value should I use for an M14 titanium bolt?

A：Generally, torque titanium bolts to approximately 70–80% of the equivalent steel torque value to avoid yielding. Exact values depend on your lubrication method and k-factor. We recommend consulting your assembly engineer for critical joints.

Q: Are these bolts compatible with carbon fiber components?

A：Yes. Titanium is galvanically compatible with carbon fiber reinforced polymer (CFRP). Unlike aluminum or steel, titanium does not create a galvanic couple that accelerates corrosion, making it the preferred fastener material in composite structures.

Q: Can you supply small prototype quantities?

A：Yes. We support prototype, small batch, and full production runs. Contact us with your drawing or specification to discuss minimum order quantities and lead times.

Q: What material certifications are available?

A：We provide MTC (Material Test Certificates), EN 10204 3.1 certificates, and Certificates of Conformance (COC) upon request. XRF composition reports are available for PMI verification.
