Stainless Steel Eye Bolts with Nuts & Washers — A2 304 Longshank Metric M3–M20

Match the thread diameter to your tapped hole or existing hardware. As a general guide: M6 (≈1/4") suits light anchoring tasks, M8–M10 (≈5/16"–3/8") covers medium-duty rigging, and M12 and above (≈1/2"+) is typically used for heavier structural or lifting applications. Also confirm the shank length — it should be long enough to pass fully through your material with enough thread exposed for the nut and washer to seat properly.

Common conversions: M3 ≈ 1/8", M4 ≈ 5/32", M5 ≈ 3/16", M6 ≈ 1/4", M8 ≈ 5/16", M10 ≈ 3/8", M12 ≈ 1/2", M14 ≈ 9/16", M16 ≈ 5/8", M20 ≈ 3/4". For shank lengths, multiply mm × 0.0394 to get inches — for example, 50mm ≈ 2".

Working load limits vary by thread diameter, shank length, and the angle of the applied load. Generally, larger diameters support greater loads — M12 and above are typically used for heavier rigging. In-line (vertical) loading generally allows higher working loads than angled loading. Always consult a load rating table for your specific size and never exceed the rated working load limit. For critical lifting, have a qualified rigger verify the setup.

Yes — A2 304 stainless steel provides good corrosion resistance for most outdoor, garden, and light marine applications. It performs well in rain, humidity, and occasional saltwater splash. For prolonged immersion or highly aggressive coastal/marine environments, A4 316 stainless steel is generally recommended. If you're unsure, contact us to discuss your specific conditions.

These eye bolts use standard ISO metric coarse threads, compatible with standard metric hex nuts, threaded inserts, and tapped holes. The included nuts and washers are matched to the same thread diameter, so no additional hardware sourcing is needed for a basic installation.

Longshank eye bolts are typically used for in-line (vertical) lifting and for anchoring ropes, cables, bungees, and chains. For angled lifting loads, a shoulder-type or swivel eye bolt rated for angular loading is generally recommended. Always follow safe rigging practices and applicable load standards for your region.

Each pack includes eye bolts, matching hex nuts, and flat washers — all in A2 304 stainless steel. The nuts and washers are sized to match the bolt's thread diameter, giving you a complete fastening set ready for installation. Pack quantities range from 1 to 40 pieces depending on the variant you select.

For one-off repairs or single anchor points, a 1- or 2-piece pack is typically the most economical choice. For larger installations — such as fitting out a workshop, deck, or trailer — bulk packs of 10, 20, or 40 pieces generally offer a lower per-unit cost. Select the pack quantity that matches your project scope to avoid over-ordering or running short mid-job.
