Titanium Grade 2 Screws manufactured at TorqBolt are of Excellent stiffness,toughness and high strength low density combination.
Dimensional standards as per ANSI B18.2.1 in imperial and ANSI B18.2.3.1M in metric are provided.
The raw material of these fasteners is classified as AeroSpace Titanium Alloys. Being a PED certified Fasteners Manufacturer by TUV Rheinland,our fasteners are accompanied with EN 10204 3.1/3.2 certification. Titanium Grade 2 Screws are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.
Titanium Grade 2 Is Stronger As Compared To Grade 1.it Has Excellent Corrosion Resistance And Cold Forgeability. This Is The Most Common Grade Used In Titanium Worldwide. We Offer Heavy Hex Bolt As Per Asme B18.2.1, B18.2.3.6m, Heavy Hex Nut As Per Asme B18.2.2 & B18.2.4, Flange Studs As Per Asme B16.5 For High Pressure, High Temperature Requirement.
Titanium Grade 2 screws are externally threaded fasteners typically driven into a tapped hole or self-tapped material. TorqBolt manufactures Titanium Grade 2 screws per ASME B18.3 (socket products), ASME B18.6.3 (machine screws), DIN 912 / 7991 / 6912, and ISO 4762 / 10642, in metric M3–M48 and imperial 0–1/2".
Drive Types
Hex socket (Allen) — ASME B18.3 / DIN 912, primary for high-torque industrial use
Titanium Grade 2 screws are available in cap (cylindrical), button (low-profile dome), countersunk / flat (82° or 90°), pan, fillister, truss, and shoulder configurations. Countersunk per DIN 7991 with 90° head angle is standard for metric; 82° per ASME B18.6.3 for imperial.
Thread & Length
Titanium Grade 2 screws use full-thread or partial-thread (length-under-head) configurations. Machine screws are typically full-thread; cap screws use partial thread for grip control. Threading per ASME B1.1 (UNC/UNF) or ISO 965 (metric coarse/fine), Class 2A or 6g default. Length-under-head is measured from the bearing surface for hex/cap, from the largest face for countersunk. Custom lengths quoted to drawing.
Specialty Screws
TorqBolt produces Titanium Grade 2 set screws (cup-point, cone-point, dog-point, flat-point, hex-socket DIN 913/914/915/916), shoulder screws (precision-ground shoulder for pivot applications), and self-tapping screws (Type AB, Type 25). All certified per EN 10204 3.1 / 3.2 with optional NACE MR0175 sour-service compliance.
Titanium & Titanium Alloys
Titanium alloys deliver an exceptional strength-to-weight ratio (density ~4.5 g/cm³, half of steel) combined with outstanding seawater + chloride corrosion resistance — the spontaneously-formed TiO₂ surface film is impervious to chlorides and most oxidizing acids. Titanium is the default for marine offshore, desalination, chemical-process, and aerospace fasteners requiring weight reduction with corrosion immunity.
Grade 2 commercially-pure (CP-Ti) is the workhorse: yield ~275 MPa, fully formable, weldable, the standard for heat-exchanger tubing and chloride-service bolting. Grade 5 (Ti-6Al-4V) is the alpha-beta alloy delivering yield ~828 MPa after solution + age treatment per AMS 4928 / ASTM B348 — the dominant aerospace + medical grade. Grade 7 / Grade 11 add Pd for crevice + reducing-acid resistance. Grade 9 (Ti-3Al-2.5V) is the high-strength tubing alloy. Grade 12 (Ti-Mo-Ni) trades strength for hot-brine corrosion performance.
Titanium fasteners ship per ASTM B348 (Grade 2 / 5) and AMS 4928 / 4965 with EN 10204 3.1 / 3.2 certificates including hydrogen (≤ 125 ppm), oxygen, and tensile testing. Welding requires inert-gas shielding (back-purged Ar) to prevent embrittlement. NACE MR0175 sour-service is fully qualified across all common grades.
