Description
A heavy adjustable bolt-on strap hinge for timber gates, with a 300 x 50mm black steel strap and an M24 threaded pin. The thick pin passes through a 35 x 25mm slot in the turned-up lug of the strap and is held there by a nut and washer on each side. Its eye turns in a 50mm wide bracket on a 150 x 80mm post plate, which bolts to the face of the post, and the strap bolts to the gate through three 12mm holes. In the box are the strap, the post plate with its pin, two nuts and two washers. The price shown is for one hinge, minimum order 2.
What you get
| Strap | One black 300 x 50mm strap with a turned-up slotted lug |
|---|---|
| Post plate and pin | One black 150 x 80mm post plate with a 50mm bracket, carrying the M24 threaded eye pin |
| Nuts and washers | Two nuts and two washers to lock the pin in the lug |
| Not included | Coach bolts or screws for the strap and the post plate |
Why choose this hinge
The biggest pin on a 300mm strap. It shares its strap length and hole spacing with the M20 hinge, but moves up to an M24 pin, a wider post plate and a wider bracket. Use it when the gate is heavy and the strap still has to stay short.
A wider plate on the post. At 150 x 80mm, with four holes at 50 x 120mm centres, the plate spreads its fixings further across the post than the M20 version does. You need a post face of 80mm or more.
Adjustable in two directions. The nuts run along a 140mm threaded shank to set the gap at the post. The 35mm slot on a 24mm pin leaves about 11mm of movement across the thickness of the gate.
A published weight limit. The supplier gives a maximum weight limit of 600kg for this hinge. It weighs about 2.47kg.

Is this the right hinge?
These six hinges work the same way but differ by strap, pin and post plate. This M24 model is the heavier partner to the M20 on the same 300mm strap. If you want a shorter, much wider strap with a bigger post plate, look at the two 220mm hinges. If the gate is light and the post is narrow, the M16 hinges have a slimmer plate and longer strap.
| Hinge | Strap | Pin | Post plate | Published maximum weight | Choose it for |
|---|---|---|---|---|---|
| M16, 400 x 40mm strap | 400 x 40mm, 4 holes | M16 | 130 x 35mm | 300kg | A slim strap on a light gate, gold coloured, narrow post |
| M16, 800 x 40mm strap | 800 x 40mm, 6 holes | M16 | 130 x 35mm | 300kg | The longest strap here, spread across wide boards |
| M20, 300 x 50mm strap | 300 x 50mm, 3 holes | M20 | 145 x 70mm | 500kg | A compact black strap with a stronger pin than the M16s |
| This hinge | 300 x 50mm, 3 holes | M24 | 150 x 80mm | 600kg | The same strap with a thicker pin and wider post plate |
| M24, 220 x 80mm strap, round hole plate | 220 x 80mm, 4 holes | M24 | 150 x 100mm | 700kg | A short, wide strap with a post plate on round holes |
| M24, 220 x 80mm strap, slotted plate | 220 x 80mm, 4 holes | M24 | 150 x 100mm | 700kg | As above, with slotted post plate holes for levelling |
Fitting
Hang the gate on two hinges, one near the top and one near the bottom. Mark the post plates so the two brackets sit directly above one another, drill the post and bolt the plates to its face. Bolt each strap flat to the gate through its three 12mm holes, using M10 coach bolts. An M24 pin carries a gate of real weight, so support it on packers or a jack before the pins go in. Feed each pin through its lug, fit a nut and washer either side, and run the nuts until the gap and level are right. Tighten the nuts against the lug last.
Care
Grease the pivot and check the lock nuts each spring. Heavy timber gates shrink and settle in their first year, so go back to the nuts after the first season and take up any drop while it is still small.
Frequently asked questions
Is the price for one hinge or a pair?
One hinge, with a minimum order of 2 because most gates use a pair. A complete hinge includes the strap, post plate, pin, two nuts and two washers.
What is the difference between this and the M20 hinge?
The strap is the same 300 x 50mm. The pin goes up from M20 to M24, the post plate from 145 x 70mm to 150 x 80mm, and the published weight limit from 500kg to 600kg.
How heavy a gate will it carry?
The supplier publishes a maximum weight limit of 600kg for this hinge. That figure is for the hinge, not a calculated rating for your gate, and the timber, the fixings and wind on the gate will all limit what it can safely do.
Can it be used on either hand of gate?
Yes. The hinge is not handed, so it suits left and right hung gates.
