304 Stainless Steel Lifting Eye Bolts — M8 to M24, Multiple Lengths

Match the thread diameter to your existing tapped hole or nut — for example, M8 fits an 8mm threaded hole (≈5/16"). For shank length, choose a size that provides at least 1.5× the thread diameter of engagement into the material. As a general guide, M8 x 20mm (≈3/4") suits light-duty panel lifting, while M12 x 50mm (≈2") is more appropriate for structural steel work. If in doubt, go one size longer — you can always add a nut to limit insertion depth.

Working load limits vary by thread size, shank engagement depth, and installation method. Generally, a properly installed M8 eye bolt can handle loads in the range of 100–200 kg in straight vertical pull, while M16 and larger sizes are typically rated for 500 kg or more. Always consult a qualified engineer and verify the rated WLL for your specific size and application before use in any lifting operation.

Yes — 304 stainless steel offers good corrosion resistance in outdoor, humid, and mildly marine environments, making it a solid choice for most exterior applications. For highly aggressive saltwater exposure or chemical environments, 316 stainless steel is generally recommended. In most standard outdoor rigging and tie-down applications, 304 SS performs reliably over the long term.

These eye bolts use standard ISO metric threads (M8 through M24), compatible with metric nuts, threaded rods, and tapped holes following DIN/ISO standards. They are not compatible with UNC/UNF (imperial) threads. If your existing hardware uses inch-based threads, please check your specifications before ordering.

Standard non-shouldered eye bolts like these are designed primarily for in-line (vertical, straight-pull) lifting. Angled or side loading significantly reduces the safe working load — in some cases by 50% or more at 45°. If your application requires multi-directional loading, consider shouldered eye bolts or swivel hoist rings rated for angular loads.

Each listing is for a single size and length combination. You can select your preferred pack quantity — 1, 2, 3, or 5 pieces — using the Pack Quantity option above. To order multiple different sizes, simply add each size as a separate item to your cart. Larger packs offer better per-unit value for projects requiring multiple anchor points of the same size.

The first number (M8) is the thread diameter; the second number is the threaded shank length. M8 x 15mm (≈19/32") has a short shank suited for thin panels or sheet metal, while M8 x 200mm (≈7.9") provides deep thread engagement for thick structural members or applications where the eye bolt must pass through a significant material thickness. Choose based on the thickness of the material you're threading into.
