Eye Bolts & Nuts

Eye bolts and eye nuts are threaded fixings with a circular loop, used to create secure suspension and lifting points for overhead rigging in theatre, TV studios and live events. Every eye bolt is rated to a specific Safe Working Load, making correct sizing essential for safe rigging practice.

MTN Shop stocks the full Doughty range in M8, M10 and M12 sizes, alongside U bolts with plates for tube and bar fixing, all rated to a specific SWL and manufactured to recognised rigging standards.

Eye Nuts by Size and Rating

The Doughty M10 Eye Nuts, available in plated, tested and plated, or black finish, cover general-purpose rigging points where an M10 thread matches your fixing. For heavier loads, the M12 Eye Nuts (340kg) and M12 Eye Nuts (500kg) give two SWL options on the same thread size, so check which rating your rigging plan calls for rather than assuming all M12 eye nuts carry the same load.

U Bolts for Tube and Bar Fixing

Where a rigging point needs to wrap around a tube rather than thread into a flat surface, the Doughty M8 U Bolts with Plates fit 32mm or 48mm tube diameters, and the Large U Bolt extends to 48-51mm tube for heavier bar and pipe fixing.

Pink Eye Nut

The Pink Eye Nut is rated to 750kg WLL, the highest capacity in this collection, suited to lifting, rigging and anchoring applications where the standard M10 and M12 options don't provide enough margin for the load.

Warranty and Load Ratings

All eye bolts and nuts sold by MTN Shop EU are genuine Doughty stock, sourced through official distribution, so full manufacturer warranty applies as it would from the brand directly. Every eye bolt and nut is stamped with its rated Safe Working Load, and this figure should never be exceeded or estimated by thread size alone, since the same thread size can carry different ratings depending on the specific model.

Choosing the Right Eye Bolt or Nut

Match the fixing to both the thread size your mounting point requires and the SWL your rigging plan calls for, checking both figures on the specific product rather than assuming a larger thread automatically means a higher rating. Where the fixing needs to wrap around a tube rather than thread into a flat surface, a U bolt is the correct choice instead of an eye nut.

Frequently Asked Questions

No, this collection stocks M12 eye nuts rated to both 340kg and 500kg. Always check the specific product's stamped SWL rather than assuming thread size alone determines the rating.
A U bolt wraps around a tube or bar to create a fixing point, while an eye nut threads directly into a flat, tapped surface. Use a U bolt where the mounting point is a tube rather than a solid, threaded structure.
SWL stands for Safe Working Load, the maximum load the fixing is rated to carry under normal use. It should never be exceeded, and every eye bolt and nut in this collection is stamped with its specific rating.
The Doughty M8 U Bolt is available for both 32mm and 48mm tube diameters, and the Large U Bolt covers 48-51mm, so check your tube's actual diameter before ordering.
