Titanium fasteners—including bolts, screws, nuts, washers

Name: Titanium fasteners—including bolts, screws, nuts, washers
Brand: ROBUST
Availability: InStock

1. Strength-to-Weight Advantage: Offers the strength of high-grade steel bolts (like Grade 8.8) but at roughly 57% of the weight.

2. Corrosion & Saltwater Immunity: Unlike steel, they do not rust or "bleed" orange streaks, even after decades of submersion in seawater.

3. Non-Magnetic: Ideal for medical devices, MRI equipment, and sensitive electronics where magnetic interference must be zero.

4. Anti-Fatigue: High resistance to vibration and cyclic stress, preventing the "snapping" common in brittle high-carbon steel.

5. Biocompatible: Often used in bone fixation and dental implants because they are non-toxic to human tissue.

Titanium Fasteners

Titanium fasteners—including bolts, screws, nuts, and washers—are the preferred hardware for applications where high strength, low weight, and total resistance to environmental degradation are required. While stainless steel fasteners are common, titanium fasteners are used when the cost of failure or the weight penalty of steel is too high.

They are primarily manufactured through Cold Heading (for smaller sizes) or Hot Forging (for larger/high-strength bolts) followed by precision thread rolling.

1. Common Grades & Specifications

Fastener selection is almost always a choice between Grade 2 (for chemistry/corrosion) and Grade 5 (for structural strength).

Grade	Strength Type	Tensile Strength	Primary Use Case
Grade 2	Standard	~345 MPa	Chemical tanks, pool equipment, marine trim
Grade 5	High Strength	~895 MPa	Racing (bikes/cars), aerospace, turbines
Grade 23	Medical	~860 MPa	Surgical implants, high-end orthodontic tools

2. Available Head Styles & Drive Types

Titanium is versatile enough to be machined into any standard fastener configuration.

Head Style	Common Drive	Typical Application
Hex Head	Wrench/Socket	Structural framing, engine mounts
Socket Cap	Allen/Hex Key	Aerospace components, precision machinery
Torx (6-Lobe)	Torx Bit	High-torque electronics, disc brake rotors
Countersunk	Phillips/Flat	Flush-mount panels, marine decks
12-Point	Multi-hex Socket	Extreme torque aerospace "flange" bolts

3. Thread Manufacturing: Cut vs. Rolled

How the threads are made is the single most important factor for titanium bolt safety.

Rolled Threads (Preferred): The metal is squeezed into shape. This compresses the grain structure, making the threads much stronger and significantly more resistant to fatigue. All aerospace and racing bolts use rolled threads.

Cut Threads: Material is removed by a lathe. This "cuts" the grain flow, creating weak points at the root of the thread. These are generally only used for low-load decorative or chemical applications.
