Aluminium 7075 Eye Bolts manufactured at TorqBolt are low density,high strength and highly malleable.
Dimensional standards as per DIN 580,ISO 3266, are provided.
The raw material of these fasteners is classified as Non-Ferrous Alloys. Being a PED certified Fasteners Manufacturer by TUV Rheinland,our fasteners are accompanied with EN 10204 3.1/3.2 certification. Aluminium 7075 Eye Bolts are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.
Aluminium 7075 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 Aluminium 7075 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
Aluminium 7075 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
Aluminium 7075 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 Aluminium 7075 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.
Aluminium Alloys
Aluminium alloys are specified for fasteners where weight reduction, electrical conductivity, or non-magnetic / non-sparking properties dominate the design envelope — aerospace structures, marine spars, electronics enclosures, and industries where reducing reciprocating mass directly improves performance. Density of ~2.7 g/cm³ (one-third of steel) combined with self-passivating Al₂O₃ surface gives respectable corrosion resistance in atmospheric service.
2024 (Al-Cu-Mg) is the high-strength aerospace alloy: yield ~325 MPa in T3 condition, used for airframe structural fasteners. 6061 (Al-Mg-Si) is the general-purpose grade with excellent weldability and corrosion, the standard for marine + structural fasteners. 7075 (Al-Zn-Mg-Cu) is the highest-strength aluminium fastener alloy: yield ~505 MPa in T6 condition, comparable to mild steel at one-third the weight — the dominant material for civilian + military aircraft assembly.
Aluminium fasteners ship per AMS 7222 / 7223 / ASTM F468 (rod) with full mechanical certification including hardness (Rockwell B 60-87), tensile, and conductivity testing. Galvanic isolation is critical when aluminium fasteners contact dissimilar metals in moist environments — cadmium plating or insulating washer + sleeve combinations are commonly specified.
