Product Description

Product Description & Key Specifications

Titanium socket head cap screws are high-value lightweight fasteners used where corrosion resistance, strength-to-weight ratio and internal hex drive access are important. This range is supplied in Grade 5 Ti-6Al-4V to DIN 912 / ISO 4762 / ASTM F468 references with M3-M16 size coverage.

Grade 5 titanium offers higher strength than commercially pure titanium while retaining strong corrosion resistance. These screws are used in aerospace equipment, medical devices, marine hardware, renewable energy accessories and specialized machinery. They are not interchangeable with steel 12.9 socket screws without checking the design load and torque behavior.

Anodized finish can be specified for appearance, identification and surface requirements. RFQs should confirm size, length, thread pitch, head dimensions, drive socket, grade, anodizing color, mating nut or tapped material, galling control and certificate requirements.

FAQ

Common Questions Before RFQ

What is Grade 5 titanium?

Grade 5 is Ti-6Al-4V, a high-strength titanium alloy used when strength-to-weight ratio and corrosion resistance are important.

Can titanium socket screws replace alloy steel 12.9 screws?

Not automatically. Titanium has different mechanical and torque behavior, so substitution should be checked against the joint design.

Are anodized colors available?

Yes. Anodized finish can be specified for appearance or identification, subject to project requirements.

Can matching titanium nuts and washers be supplied?

Yes. Matching titanium hex nuts and flat washers can be supplied for through-bolted assemblies.

What information is needed for an RFQ?

Send standard, size, length, grade, anodizing requirement, quantity, mating material and certificate scope.

Need Grade 5 titanium socket head cap screws?

Send size, length, standard, anodizing requirement, quantity and certificate needs. We can quote M3-M16 Ti-6Al-4V socket screws with matching titanium nuts and washers.
