Expansion Anchor Eye Bolts Hook — Grade 8.8 Galvanized Steel for Concrete & Brick | M6.5 M8 M10 M12

Match the bolt diameter to your anchor hole size and load requirement. As a general guide: M6.5×40mm (≈1/4") suits lighter fixtures typically up to ~30 kg; M8×45mm (5/16") handles medium loads; M10×60mm (3/8") is suited for heavier applications; M12×70mm (1/2") is appropriate for structural or high-load anchoring. Embedment depth should generally be at least 10× the bolt diameter for reliable grip in concrete.

Grade 8.8 carbon steel typically provides a tensile strength of 800 MPa and a yield strength of 640 MPa. Actual working load limits depend on the installed size, embedment depth, base material condition, and the safety factor applied. For critical overhead or structural applications, always consult a licensed structural engineer and apply an appropriate safety factor (commonly 4:1 or higher).

Yes, for general outdoor use. The galvanized zinc coating provides corrosion resistance against moisture and mild atmospheric exposure. For permanently submerged installations or highly corrosive environments such as coastal saltwater or chemical exposure, stainless steel anchors are generally recommended instead.

These anchors use standard ISO metric coarse threads. M6.5, M8, M10, and M12 are compatible with standard metric nuts, washers, and hardware. They are not designed for UNC or UNF inch-thread systems. If you need to attach a nut or additional hardware to the shank, use the corresponding metric size.

These expansion anchor eye bolts are designed for solid concrete and solid brick. They are generally not recommended for hollow block, aerated concrete (AAC/Ytong), soft masonry, or drywall without first verifying pull-out values for that specific substrate. In hollow or lightweight materials, use a toggle bolt or chemical anchor instead.

Each listing lets you select 1, 3, 5, 10, or 20 pieces. For a single hanging point — such as a heavy bag or a single cable drop — 1 piece is sufficient. For a cable tray run, gym rig, or suspended shelf system, the 10- or 20-piece option typically offers better per-piece value. Order a few extras to account for installation adjustments.

Yes. Use a carbide-tipped masonry or SDS hammer drill bit matching the anchor's nominal diameter (e.g., an 8 mm bit for M8 anchors). Drill to the required embedment depth, blow or vacuum out the dust, insert the anchor, and tighten the bolt until the expansion sleeve grips the base material firmly. Do not over-torque, as this can crack the surrounding concrete.
