M6 Stainless Steel Eye Bolts — Threaded Ring Screws for Catenary Wire & Resin Hanging

Measure the thickness of the material you are threading into. The M6×30mm (≈1.18") shank works well for thinner substrates such as resin panels or light timber up to about 20mm thick. The M6×60mm (≈2.36") provides deeper engagement and is generally preferred for thicker beams, concrete anchors, or applications where pull-out resistance is critical. As a rule of thumb, aim for at least 1.5× the bolt diameter of thread engagement in the base material.

Working load limits depend on the installation angle and base material. For a vertically loaded M6 stainless steel eye bolt in a solid substrate, the working load is typically in the range of 50–100 kg (110–220 lb) when properly torqued. Always apply a safety factor of at least 4:1 for overhead or dynamic loads. Contact us to confirm load ratings for your specific application.

Yes. Stainless steel offers strong resistance to rust and oxidation in most outdoor environments, making these eye bolts a solid choice for patio catenary wire installations, garden structures, and exterior lamp mounts. For coastal or marine applications with prolonged saltwater exposure, we generally recommend verifying the specific grade (304 vs 316) before installation, as 316 stainless provides superior chloride resistance. Contact us to confirm the grade for your order.

These eye bolts use the metric M6 thread standard with a standard coarse pitch of 1.0mm. They are not compatible with imperial (UNC/UNF) threaded holes. If your project uses imperial hardware, you will need an adapter or a different fastener. M6 metric threads are widely used in European-standard fixtures, flat-pack furniture inserts, and most modern DIY hardware.

Yes — this is one of the most common use cases for this style of eye bolt. The closed ring provides a secure anchor point for hooks, carabiners, or wire loops used in pendant lamp and chandelier installations. Thread the bolt into a pre-tapped hole or threaded insert in the resin lamp body, then attach your hanging wire or chain through the ring. Always ensure the ceiling or beam anchor point is rated for the combined weight of the fixture.

A standard catenary wire run between two anchor points requires a minimum of 2 eye bolts — one at each end. For longer spans with intermediate support points, you will need additional eye bolts at each support. The 5-pack option is a cost-effective choice for multi-point installations across a pergola, fence line, or workshop ceiling, or when you want spares on hand for future projects.

For installation into pre-tapped holes or soft materials like resin, these can often be hand-tightened or turned with a screwdriver or rod passed through the eye. For harder substrates such as timber or masonry (with an anchor), pre-drill a pilot hole slightly smaller than 6mm and use a wrench or pliers for final torquing. Always ensure the shank is fully engaged before applying any load.
