M16 Eye Bolt 304 Stainless Steel Threaded Ring Lifting Screw — 60mm to 200mm

Measure the thickness of the material you are bolting through, then add enough length for full nut engagement. As a general rule, thread engagement should be at least 1× the bolt diameter (16mm minimum). For example, if your material is 50mm thick, a 80mm (≈3.1") bolt typically provides enough thread for a nut and washer. Available lengths run from 60mm (≈2.4") to 200mm (≈7.9") — when in doubt, size up.

M16 eye bolts in 304 stainless steel typically support a vertical working load in the range of 500–1,000 kg, but the actual limit depends on the load angle, installation method, and anchor material. Side-loading (off-axis) significantly reduces capacity. For safety-critical lifting applications, always verify with a qualified engineer and use hardware with a certified WLL rating.

Yes. 304 stainless steel provides strong resistance to rust and atmospheric corrosion, making it well-suited for outdoor catenary wire installations, garden structures, and covered marine applications. For continuous saltwater immersion or highly corrosive coastal environments, 316 stainless steel is generally recommended. Rinse with fresh water periodically to extend service life in coastal areas.

This bolt uses a standard M16 × 2.0mm metric coarse thread, which is the most common M16 thread pitch used worldwide. It is compatible with any standard M16 hex nut, flange nut, lock nut, or threaded insert. It is not compatible with UNC/UNF inch-standard hardware.

Full Thread (available in 60mm and 70mm lengths) means the threaded shank runs the entire bolt length, giving you maximum flexibility for shallow tapped holes or thin materials. b=70mm variants (80mm–200mm) have a fixed 70mm threaded section at the end of the shank — the upper portion is unthreaded. This is the standard configuration for longer structural bolts where only the end needs to engage a nut.

Yes — these M16 stainless steel eye bolts are commonly used as fixed anchor points for catenary wire systems, suspended string lights, hanging cables, and overhead rigging. Ensure the bolt is fully threaded into a structurally rated anchor (timber beam, concrete insert, or steel plate) and that the total load, including dynamic forces, stays within the working load limit. Use a shackle or wire rope clip rated for M16 hardware.

In most through-bolt applications, yes — a standard M16 nut and flat washer are required and are not included with this listing. If you are threading the bolt directly into a tapped hole or a threaded anchor plate, no nut is needed. A lock washer or nylon insert lock nut is recommended in vibration-prone environments to prevent loosening over time.
