Description
A compact adjustable gate hinge for heavy steel gates. A zinc-plated M20 eye bolt screws into a flanged nut that you weld to the gate post, and its eye is pinned inside a small U bracket that you weld to the gate. Turn the bolt in or out of the nut to set the gap and bring the gate back square, now or years later. Rated for gates up to 500kg on two hinges. The price is for one complete hinge, minimum order 6.
Why choose this hinge
Small and strong. The whole hinge sits in the gap between gate and post, with a thick M20 bolt doing the work. Neat on modern box-section gates.
Adjust after hanging. Gates sag and posts lean over time. Wind the bolt in or out of the nut to pull the gate back level, with no cutting or re-welding.
Rated for 500kg. Two hinges carry driveway gates, yard gates and heavy pedestrian gates.
Everything included. Bolt, bracket, pin with socket cap and the flanged weld nut, all zinc plated.
Where it is used
Steel driveway gates, industrial and yard gates, heavy pedestrian gates, railings gates and replacing worn hinges on existing steel gates.

Fitting
Use two hinges per gate leaf, one near the top and one near the bottom. Grind off the zinc where you will weld, and weld with good ventilation. Weld each flanged nut to the side of the post, flange flat to the post face, with the two nuts in one vertical line. Screw the bolts in, fit each U bracket on its eye with the pin, then stand the gate on packers and weld the brackets to the gate stile. Keep heat away from the pin and thread. Take the packers out, turn the bolts until the gate hangs level, then paint the welds with zinc-rich primer.
Care
Grease the pin and the thread once a year. Check the gate still hangs level each spring and give the bolt a turn if it has dropped.
Frequently asked questions
Is the price for one hinge?
Yes, one complete hinge. The minimum order is 6, enough for three gate leaves.
Can I fit it without welding?
No. The nut welds to the post and the bracket welds to the gate. For a bolt-on fixing choose a hinge with a back plate.
How much adjustment does it give?
The bolt has 44mm of thread, so the gate can move in or out by roughly 20 to 25mm once enough thread is engaged in the nut.
Is it left or right handed?
Neither. It works on either side.
Will it carry a 500kg gate on its own?
No. The 500kg rating is for a gate hung on a pair of hinges. Heavy gates also need a firm post and a stop or wheel.
