M10 Titanium 12-Point Nut

Product Overview

The M10 Titanium 12-Point Nut (also known as Bi-Hex or Double Hex) is engineered for applications where weight reduction, high strength, and compact tool access are critical. Unlike standard hex nuts, the 12-point design allows for higher torque transmission without rounding off corners and fits into tighter spaces using smaller sockets.

Material Selection: Gr5 vs. Gr2

We offer two distinct material grades tailored to your specific application requirements:

• Grade 5 (Ti-6Al-4V): The aerospace standard. With a tensile strength of ≥895 MPa, it is suitable for high-stress structural components, suspension systems, and racing wheel hubs.
• Grade 2 (Commercially Pure Titanium): Provides excellent protection against rust for parts that don’t carry heavy loads, like cases for marine,

Why Choose Our CNC Titanium Nuts?

• Micron-Level Precision: Manufactured via Swiss-type CNC turning centers, achieving dimensional tolerances of ±0.002mm to ±0.005mm, far exceeding cold-forged standards.
• Anti-Galling Thread Finish: Threads are precision-cut and polished to Ra ≤0.4μm, minimizing friction and the risk of cold welding (galling) during installation.
• Drawing-Based Customization: We accept STEP/IGS/DXF files to customize thread pitch (e.g., M10x1.0/1.25), flange diameter, or add safety wire holes.
• Full Traceability: Every batch is supplied with an EN10204 3.1 Material Test Certificate (MTC), tracking the chemical composition back to the titanium sponge.

Key Technical Specifications

Note: Dimensions for “Across Flats” (AF) and Flange Diameter can be customized according to your drawings. Please upload your .STEP or .PDF file in the inquiry form for a precise quote.

Surface Treatment & Aesthetics

We provide a range of surface finishes that enhance both the visual appeal and functional performance of the titanium nuts.

1. PVD Coating (Physical Vapor Deposition)

Recommended for high-wear applications. PVD creates a hard, thin ceramic layer on the titanium surface.

• Benefits: increase surface hardness (HV > 2000), provide excellent scratch resistance, and significantly reduce the friction coefficient to prevent thread galling.
• Colors Available: PVD Black, PVD Gold.

2. Anodizing

Ideal for color coding or aesthetic customization in motorsport and modification.

• Benefits: Creates a vivid, uniform oxide layer without adding dimensional thickness.
• Colors Available: Burnt Blue (Gradient), Purple, Green, Gold, and Rainbow.

3. Functional Finishes

• CNC As-Machined: Standard bright silver finish with visible precision turning lines.
• Mirror Polish: Hand-polished to Ra 0.1, creating a jewelry-like chrome effect.
• Bead Blasted: Matte grey finish, non-reflective, suitable for tactical or industrial instruments.

Manufacturing & Quality Assurance

Quality is not inspected in; it is manufactured in. Our facility utilizes advanced CNC technology to ensure every M10 titanium nut meets aerospace specifications.

The CNC Difference

Unlike mass-produced cold-forged nuts which often suffer from micro-cracks and rounded corners, our CNC Machined nuts are turned from solid titanium bars. This ensures:

• Perfect Concentricity: Ensuring the nut seats perfectly flat against the flange.
• Sharp 12-Point Corners: Providing maximum grip for sockets without slipping.
• Burr-Free Threads: Microscopic inspection ensures no metal shavings remain, protecting your bolts.

Quality Control Protocol

• 100% Thread Gauging: Every production lot is checked with Go/No-Go gauges (Class 6H) to guarantee fitment.
• Spectral Analysis: We verify Fe, O, C, N, and H content to ensure compliance with ASTM B348.
• Visual Inspection: 100% visual check for surface defects under 10x magnification before packaging.

Application & Installation Tips

Industry Applications

• Motorsport & Racing: Wheel nuts, sprocket nuts, and exhaust manifold fasteners. (Reduces unsprung weight for better handling).
• Aerospace: Non-structural and secondary structural fastening requiring high strength-to-weight ratios.
• Medical & Marine: Wheelchair assembly, marine sensors, and chemical processing equipment (Grade 2 recommended for seawater).

Installation Guide: Preventing Galling

Titanium threads can be prone to “galling” (cold welding) when tightened against other metals without lubrication.

1. Use Anti-Seize: We strongly recommend applying a high-quality Molybdenum Disulfide (MoS2) or Copper-based anti-seize paste to the threads before installation.
2. Recommended Torque: For M10 Gr5 Titanium Nuts, typical torque settings range from 45Nm to 55Nm (varies by application and lubrication). Always consult your equipment manual first.
3. Do Not Over-Torque: Titanium has a lower modulus of elasticity than steel; use a calibrated torque wrench.

Frequently Asked Questions (FAQ)

Q1: What is the difference between Gr5 and Gr2 titanium nuts?

A: Gr5 (Ti-6Al-4V) is an alloy with high strength (Tensile ≥895MPa), suitable for racing and load-bearing parts. Gr2 is commercially pure titanium, softer but with excellent corrosion resistance, ideal for chemical or marine use.

Q2: Can you manufacture M10 nuts with a custom fine pitch (e.g., 1.0mm)?

A: Yes. Since we use CNC machining, we can produce any thread pitch (1.0, 1.25, 1.5) according to your requirements. Just specify the pitch in your inquiry.

Q3: Is there a Minimum Order Quantity (MOQ)?

A: For standard sizes (M10x1.25/1.5 Gr5), we have stock with no MOQ. For custom dimensions or PVD colors, the MOQ starts from 50-100 pieces depending on the complexity.

Q4: Do you provide drawings for validation?

A: Yes, we accept your STEP/DXF files for review. For custom orders, we can provide a CAD drawing for your approval before mass production.
