DIN 580 Lifting Eye Bolts & Nuts — Reliable Overhead Rigging in G80 & 12.9 Manganese Steel
When a lifting point fails mid-job, the consequences go far beyond a dropped load. Contractors, riggers, and maintenance engineers who work with hoists, cranes, and chain blocks need DIN 580 lifting eye bolts they can trust — hardware that won't stretch, crack, or strip under dynamic load. Whether you're rigging machinery in a fabrication shop or securing structural components on a job site, the wrong fastener grade is never an option.
Each piece in this lineup is a single DIN 580 lifting eye bolt or eye nut machined from manganese steel in your choice of two strength grades: G80 (Grade 80) — the industry-standard alloy for certified overhead lifting hardware — or 12.9 class for extreme-torque fastening applications. Thread sizes span M6 (≈1/4") through M36 (≈1-7/16"), covering the full range of light-duty rigging points up to heavy industrial anchor applications. Both bolts and nuts are available, letting you build a complete lifting attachment from a single source.
Typical use cases include attaching lifting points to engine blocks and gearboxes during overhaul, rigging structural steel beams on construction sites, securing load-bearing anchor points in warehouse racking systems, and serving as high-strength fasteners in heavy equipment assembly — all scenarios where a DIN 580 manganese steel eye bolt with a verified grade marking is the specification of choice.

❓ Frequently Asked Questions
How do I choose the right size lifting eye bolt for my application?
Match the thread size to your existing tapped hole or mating nut. Sizes in this range go from M6 (≈0.24" / 6 mm) up to M36 (≈1.42" / 36 mm). As a general rule, always select a size whose rated Working Load Limit (WLL) exceeds your actual load by a safety margin of at least 4:1. When in doubt, size up — an oversized eye bolt is always safer than an undersized one.
What is the difference between G80 and 12.9 grade manganese steel?
G80 (Grade 80) is a lifting-specific alloy steel grade standardized for overhead rigging hardware, with a minimum tensile strength typically around 800 MPa. It is the grade specified for certified lifting chains, hooks, and eye bolts used in hoisting applications. 12.9 is a metric property class for fasteners with a minimum tensile strength of 1220 MPa — making it suitable for high-stress structural and mechanical fastening. Choose G80 for certified overhead lifting; choose 12.9 for high-torque fastening where a lifting certification is not required.
What is the Working Load Limit (WLL) of these eye bolts?
WLL varies by size and grade. G80 DIN 580 eye bolts generally have a WLL ranging from approximately 0.16 t for M6 up to several tonnes for larger sizes such as M24 and above. The 12.9 grade variants are rated for tensile fastening loads rather than overhead lifting WLL. Please contact us to confirm the rated capacity for your specific size and grade before use in any lifting application.
Can these eye bolts and nuts be used outdoors or in wet environments?
Manganese steel provides excellent mechanical strength but is not inherently corrosion-resistant in the way stainless steel is. For outdoor or high-humidity environments, we recommend applying a rust-inhibiting coating or lubricant and inspecting regularly for surface oxidation. For permanently wet or chemically aggressive environments, a stainless steel alternative is generally more appropriate.
Are these compatible with standard metric lifting chains and shackles?
Yes. DIN 580 eye bolts use standard metric coarse threads and are compatible with ISO metric tapped holes, Grade 80 lifting chains, and shackles designed for the same thread pitch. Always verify that the ring opening diameter of the eye bolt is large enough to accept your shackle pin or hook, and that thread pitch matches your mating hardware.
Should I use an eye bolt or an eye nut for my setup?
Eye bolts are used when you need to thread a lifting point directly into a tapped hole in your workpiece, or pass through a clearance hole and secure with a standard nut on the back side. Eye nuts are used when a threaded stud or rod already protrudes from your structure — you simply thread the eye nut onto the stud to create the lifting attachment point. Both are available in this listing; select the appropriate type from the variant options.
Is this product sold individually or in sets?
Each listing is sold per piece (1 pc) by default. If you need multiple pieces, simply adjust the quantity at checkout or select a multi-pack option if available in the Pack of Quantity variant selector above. Ordering per piece lets maintenance teams and project engineers purchase exactly the count specified in their BOM without overstocking.
