Frequently Asked Questions on Titanium Socket Head Bolts
Expert engineering insights regarding torque specifications, galling prevention, material selection, and custom order logistics.
Why choose Titanium Socket Head Bolts over Grade 12.9 Steel or Stainless Steel?
Titanium Grade 5 (Ti-6Al-4V) socket head bolts deliver an extraordinary strength-to-weight ratio (950+ MPa tensile strength while being ~45% lighter than steel). Unlike standard 304/316 stainless steel, titanium will not suffer pitting in harsh seawater or chemical environments. Furthermore, titanium exhibits superior fatigue resistance and does not become brittle in cryogenic environments.
How do you prevent thread galling (cold welding) during titanium bolt installation?
Like stainless steel, titanium fasteners can experience galling under high frictional torque. BJCJTi recommends applying an anti-seize lubricant (such as molybdenum disulfide, nickel-based paste, or copper anti-seize) to the threads. Additionally, we provide precision rolled threads with smoother micro-surface finishes and optional low-friction PVD coatings to eliminate galling tendencies.
What standards and head styles are available for your socket bolts?
We manufacture DIN 912 (ISO 4762) Socket Head Cap Screws, DIN 7991 / ISO 10642 Countersunk Flat Socket Screws, ISO 7380 Button Head Socket Screws, DIN 913/914/916 Set Screws, Tapered Allen Screws, Flanged Socket Bolts, and bespoke 12-point bolts in Metric sizes from M2 to M36 and Imperial sizes from #4-40 up to 1-1/2".
Can BJCJTi provide customized OEM/ODM machining from CAD drawings?
Yes. Over 40% of our production consists of custom-engineered OEM/ODM fasteners. Send us your 2D/3D STEP/DWG drawings, required tolerances, alloy grade, and finishing specs. We offer rapid prototype sampling within 7 working days.
