Titanium Alloy Socket Head Cap Screws with Washer

Premium Titanium Alloy Socket Head Cap Screws with Washer – Lightweight Fastening Solutions for High-Performance Applications

Baoji Chuanglian New Metal Material Co., Ltd. manufactures M5 Titanium Alloy Socket Head Cap Screws with Washer using aerospace-grade Ti-6Al-4V material with a verified tensile strength of minimum 950 MPa. Each screw weighs approximately 1.5g—delivering 45% weight reduction compared to steel equivalents—while maintaining structural integrity under extreme conditions. Available in lengths from 8mm to 50mm with 0.8mm pitch precision, these fasteners include flat washers (OD 10mm × ID 5.2mm) and feature cylindrical socket heads compatible with 4mm hex keys. Manufactured under ISO 9001 certification, every batch undergoes tensile testing and chemical composition verification to ensure compliance with international aerospace and industrial standards.

Why Choose Ti-6Al-4V Grade 5 Titanium Socket Fasteners

The selection of Ti-6Al-4V alloy for socket head cap screws delivers measurable performance advantages across critical applications. This Grade 5 titanium contains 5.5–6.75% aluminum and 3.5–4.5% vanadium, creating an alpha-beta phase structure that provides superior fatigue resistance compared to commercially pure titanium grades.

Your engineering projects benefit from a material density of 4.43 g/cm³—enabling significant mass savings in aerospace assemblies, racing vehicles, and robotic systems where every gram impacts performance. The spontaneous formation of a TiO2 passive oxide layer ensures exceptional corrosion resistance in marine environments, chemical processing equipment, and medical devices exposed to bodily fluids.

Unlike stainless steel fasteners that suffer stress corrosion cracking in chloride-rich environments, Titanium Alloy Socket Head Cap Screws with Washer maintain structural integrity when exposed to saltwater, acids, and industrial solvents. The included flat washer distributes clamping loads evenly, preventing surface deformation on composite materials and soft alloys.

Technical Specifications

Application Scenarios You Can Trust

Aerospace manufacturers integrate these fasteners into fuselage panels and UAV frames where low-profile heads minimize aerodynamic drag. The reduced weight directly translates to extended flight duration and increased payload capacity—critical factors in commercial and defense aviation.

Motorsport teams rely on socket head cap screws for securing carbon fiber bodywork and suspension components. The material's low galvanic potential difference with carbon composites prevents the aggressive corrosion that destroys aluminum fasteners within weeks of track exposure.

Medical device manufacturers specify these screws for external fixation frames and surgical instrument assemblies. Titanium's biocompatibility eliminates toxic leaching risks, while the included washer provides uniform pressure distribution across bone interfaces and polymer housings.

Marine engineering projects utilize Titanium Alloy Socket Head Cap Screws with Washer in desalination plants, offshore platforms, and submersible vehicles. The fasteners withstand continuous saltwater immersion without pitting or crevice corrosion that compromises structural joints.

Installation Guidelines and Anti-Galling Protection

Proper installation techniques prevent the cold welding phenomenon known as galling—a common issue when titanium contacts titanium under high pressure. You should apply molybdenum disulfide (MoS2) anti-seize compound to threads before assembly, reducing the friction coefficient by approximately 40%.

Torque specifications for M5 titanium socket screws typically range from 70–80% of equivalent steel fasteners due to the material's lower modulus of elasticity (114 GPa versus steel's 200 GPa). We recommend using calibrated torque wrenches and consulting dry versus lubricated torque charts to prevent head shearing or thread stripping.

The cylindrical socket head design requires clean hex key engagement to avoid cam-out during tightening. Ensure the 4mm Allen key fully seats into the socket before applying rotational force. Worn or damaged keys should be replaced immediately to maintain proper torque transfer.

Quality Assurance and Manufacturing Excellence

Baoji Chuanglian operates CNC machining centers and thread rolling equipment that produce fasteners meeting ASTM B348 and AMS 4928 specifications. Thread rolling follows the material's grain structure rather than cutting through it, resulting in 30% higher fatigue strength compared to machined threads.

Every production batch undergoes spectrometry analysis to verify aluminum and vanadium percentages, preventing material substitution fraud. Tensile testing confirms minimum 950 MPa ultimate strength, while Rockwell hardness verification (HRC 30–39) ensures proper heat treatment efficacy.

Hydrogen embrittlement testing protects against delayed fracture in aerospace-grade applications. Thread metrology using Go/No-Go gauges ensures Class 6g fitment tolerance, guaranteeing consistent assembly performance across your production line.

Packaging and Logistics

Titanium Alloy Socket Head Cap Screws with Washer ship in anti-rust polyethylene bags containing 100 pieces per unit. Each bag displays laser-etched labels identifying material grade, thread size, length, and batch traceability codes required for aerospace documentation.

Bulk orders utilize moisture-barrier foil pouches with desiccant packs, maintaining material integrity during sea freight transit. Lead times range from 10–20 days depending on order volume and customization requirements. Air freight options expedite delivery for urgent projects requiring rapid prototyping or production line continuity.

Frequently Asked Questions

What causes galling during installation of titanium socket screws?

Titanium's thin oxide layer can wipe away under clamping pressure, causing metal-to-metal adhesion. Always use MoS2 anti-seize paste or specify DLC-coated fasteners to reduce friction coefficients and prevent cold welding.

Can these screws directly replace Grade 12.9 steel bolts?

Grade 5 titanium offers strength comparable to Grade 10.9 steel (approximately 1000 MPa), not the 1200+ MPa of Grade 12.9. For high-stress joints, perform structural analysis or increase bolt diameter to compensate for strength differences.

How do these fasteners perform with carbon fiber components?

Titanium creates minimal galvanic potential difference with carbon composites, preventing the rapid corrosion that destroys aluminum fasteners. This makes Titanium Alloy Socket Head Cap Screws with Washer the preferred choice for composite assemblies in aerospace and automotive applications.

What torque specifications should I follow?

Apply 70–80% of standard steel bolt torque values to prevent thread stripping. Always use calibrated torque wrenches and follow manufacturer-provided charts that account for dry versus lubricated installation conditions.

Are rolled threads stronger than cut threads?

Yes. Thread rolling aligns with the material's grain structure, producing 30% higher fatigue strength and superior shear resistance compared to machined threads—making rolled threads mandatory for aerospace applications.
