Aisi 410 Stainless Steel Eye Bolts manufactured at TorqBolt are corrosion resistant,low maintainence,silver finish.
Dimensional standards as per DIN 580,ISO 3266, are provided.
The raw material of these fasteners is classified as Martensitic Stainless Steel. Being a PED certified Fasteners Manufacturer by TUV Rheinland,our fasteners are accompanied with EN 10204 3.1/3.2 certification. Aisi 410 Stainless Steel Eye Bolts are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.
AISI 410 Stainless Steel Eye bolts are externally threaded fasteners with an integral head, manufactured per ASME B18.2.1, ISO 4014/4017, and DIN 933/931. TorqBolt produces AISI 410 Stainless Steel Eye bolts in metric (M6–M100) and imperial (1/4"–4") diameters with custom lengths from 10 mm up to 3000 mm.
Head Styles Available
Hex head — ASME B18.2.1, the workhorse for general bolting
Heavy hex head — thicker head for high-load joints, ASTM A325 / A490 patterns
Socket head cap (SHCS) — ASME B18.3 / DIN 912, ideal where space is limited
AISI 410 Stainless Steel Eye bolts are supplied with full or partial threading. Full-thread (UNC, UNF, ISO metric coarse/fine) for tension-only joints; partial-thread shank for shear loads where the unthreaded grip carries the load. Thread fits per ASME B1.1 (Class 2A) or ISO 965 (6g) by default; tighter Class 3A / 4h6h fits available on request. Engagement length follows the 1.5×D rule for tapped holes; 1.0×D minimum on through-bolting.
Mechanical Performance
AISI 410 Stainless Steel Eye bolts achieve characteristic tensile strength, yield, and elongation per the source-material spec, with proof-load testing and hardness verification per ASTM F606 / ISO 898-1. Torque-tension calibration is published per ASME PCC-1 for critical joints. Each lot ships with EN 10204 3.1 (or 3.2 on request) certificates listing chemistry, mechanicals, hardness, and dimensional inspection.
Custom Configurations
TorqBolt can produce AISI 410 Stainless Steel Eye bolts to drawing, with non-standard heads, drilled-shank variants, double-end, captive, or matched-set configurations. Coatings include zinc, PTFE, Xylan, hot-dip galvanized, and electroless nickel. NACE MR0175 / ISO 15156 sour-service certification on request.
Martensitic Stainless Steel (400-series)
Martensitic stainless steels are body-centered tetragonal Fe-Cr alloys (typically 12-17% Cr, >0.1% C) that respond to quench + temper heat treatment, achieving high hardness and tensile strength while retaining moderate corrosion resistance. They are magnetic and used where mechanical strength is critical and corrosion exposure is mild.
AISI 410 (UNS S41000) is the general-purpose grade for valve trim, pump shafts, turbine blades, and high-strength bolting; quench from 950-1010°C + temper at 200-700°C dial in tensile strength from 600 to 1200 MPa. AISI 416 is the free-machining variant (S+P additions). AISI 420 raises C for higher hardness (cutlery, surgical instruments). AISI 431 adds Ni for marine + aerospace fasteners. AISI 440A/B/C are the highest-hardness grades (HRC 56-60) for bearings and ball valves.
Martensitic fasteners are supplied per ASTM A276 / A479 with hardness, tensile, and impact testing per the heat-treat condition. EN 10204 3.1 / 3.2 certs standard. NACE MR0175 service is restricted — martensitic grades are SSC-susceptible above HRC 22 hardness, requiring careful temper-control for sour applications.
