ISO14580 M4 Titanium Bolts — Hexalobular Socket Cheese Head Fasteners for Lightweight Precision Applications

ISO14580 m4 titanium bolts are hexalobular socket cheese head screws manufactured from titanium alloy, designed for applications where weight reduction, corrosion resistance, and drive reliability are critical. These M4 bolts meet the dimensional requirements of ISO 14580. These bolts include a low profile cylindrical head with a Torx drive mechanism and 0.7mm thread pitch. They are made from Titanium Grade 5 (Ti-6Al-4V) which has a tensile strength of 895 MPa or more and are around 45% lighter than steel counterparts. 8–30mm long. Anodized or brilliant polished finish.

Why Choose Our ISO14580 M4 Titanium Bolts

This is a big reason purchasers step up from regular hex or Phillips fasteners to the hexalobular (Torx) drive mechanism. It distributes the driving power equally to six contact lobes . This prevents cam-out failure, and allows more torque to be transferred without harming the titanium head .

Titanium Grade 5 (Ti-6Al-4V) has a high strength-to-weight ratio. Bolts have about 60% the density of steel (4.51 g/cm³) yet may retain their structural integrity under high loads. Their spontaneous passive oxide coating renders them almost impervious to seawater, chlorides and oxidizing acids.

Whether you are creating racing drones, maritime enclosures or medical imaging equipment these bolts are built to perform where dependability and accuracy matter most.

Lightweight Drone Bolts: M4 titanium bolts hold the arms of a carbon fiber frame together where every gram counts. The Torx drive provides for accurate torque without stripping during field maintenance and titanium’s galvanic compatibility avoids frame corrosion at the fastener contact.

Marine Navigation & Sensor Enclosures: Salt spray and constant moisture demand corrosion-proof fasteners. The hexalobular drive maintains reliable torque for O-ring compression even after repeated exposure to seawater — a point where stainless steel hex bolts commonly fail.

Medical Imaging Equipment (MRI): Titanium's non-ferromagnetic property makes these bolts essential in MRI assembly. The secure Torx drive prevents tool slippage near sensitive superconducting magnets, making them a preferred choice for precision instrument builders.

Cycling & Instrumentation: Weight-conscious cyclists and instrument designers use these bolts for component mounting where a combination of low weight, corrosion resistance, and aesthetic finish is required.

Material Features

Baoji Huacan New Metal Materials Co., Ltd. operates from China's "Titanium Valley" in Baoji, Shaanxi Province — the heart of China's titanium industry. Our facility runs 40+ high-precision CNC lathes, CNC machining centers, and gantry machining centers.

With 10+ years of titanium machining experience and annual production capacity exceeding 1,000 tons, we support everything from prototype batches to high-volume orders. Our upstream capabilities — including VAR melting and precision bar rolling — give us full traceability from raw ingot to finished fastener.

We serve 100+ international clients across aerospace, marine, medical, and industrial sectors.

Production begins with verified titanium bar stock meeting ASTM B348 standards. Material composition is confirmed by XRF spectrometry before machining starts.

CNC precision turning shapes each bolt's cheese head geometry and M4 thread to ISO 14580 tolerances. Our 40+ CNC lathes and machining centers ensure consistent dimensional accuracy across both prototype and bulk production runs.

Thread rolling or cutting is followed by Go/No-Go gauge verification to confirm the 6g thread fit class. Surface finishing — anodizing or bright polishing — is applied as the final production step before inspection.

Q: What is the torque recommendation for M4 Grade 5 titanium ISO 14580 bolts?

A：A general guideline is 3.0–4.0 Nm. Always use a calibrated torque wrench — tactile tightening frequently causes thread yield in titanium fasteners.

Q: How do I prevent galling during installation?

A：Apply a molybdenum disulfide-based anti-seize paste. Alternatively, specify an anodized finish to modify surface friction and reduce cold-welding risk.

Q: Should I choose Grade 2 or Grade 5 for my application?

A：Choose Grade 5 (Ti-6Al-4V) for structural or load-bearing assemblies requiring ≥895 MPa tensile strength. Choose Grade 2 if chemical resistance and ductility take priority over strength.

Q: Are these bolts compatible with carbon fiber frames?

A：Yes. Titanium is galvanically compatible with carbon fiber, unlike aluminum which corrodes rapidly in contact with CF in the presence of moisture.

Q: Can you produce custom lengths outside 8–30mm?

A：Yes. We manufacture according to customer drawings and specifications. Submit your requirements to sherry@hc-titanium.com for a tailored quote.
