Description
A clean, strong weld-on hinge for steel gates. This 150mm bullet hinge is turned from solid steel in two halves: the bottom half carries an 18.5mm pin and welds to the post, the top half welds to the gate and drops over the pin. Once painted it disappears into the gate line, with nothing to bolt, adjust or work loose, and the gate lifts straight off the pin when you need to take it down. The price is for one hinge (both halves), minimum order 6.

Why choose a machined bullet hinge
Solid, not pressed. Both halves are machined from solid steel bar with a turned pin, so the pin runs true in its bore and the hinge does not rock or rattle.
Neat. A plain round barrel with domed ends, no straps or bolts on show. It suits ornamental railings and modern flat-bar gates alike.
Lift-off. The gate lifts off for painting, repairs or wide deliveries, and drops back on with no tools.
Ready to weld. Bright, uncoated steel takes a clean weld with no plating to grind off first.
Where it is used
Steel garden, side and driveway gates, railing gates and pedestrian gates, metal doors on bin stores and plant rooms, steel shutters, trailer gates and tailboards, and fabrication work where a strong hidden pivot is needed.

Fitting
Use two hinges per gate leaf, one near the top and one near the bottom. Stand the gate in the opening on packers with an even gap at the hinge side. Put the two halves of each hinge together, pin end down, and hold the barrel in the corner between the gate stile and the post. Check both hinges are in one vertical line, then tack the bottom halves to the post and the top halves to the gate. Lift the gate off to check it swings freely, then weld out fully. Keep weld spatter out of the joint, let it cool, and add a few drops of oil through the hole.
Care
Paint the barrel with the gate, keeping paint out of the joint. Oil through the hole twice a year so the gate stays quiet and does not wear the pin. If the gate drops over the years, a hardened washer between the halves lifts it back.
Frequently asked questions
Is the price for one hinge?
Yes, one complete hinge in two halves. The minimum order is 6, enough for three gate leaves.
Can I bolt it on?
No. It is made to be welded. For a bolt-on fixing see our adjustable gate hinges with back plates.
Which way up does it go?
The half with the pin goes at the bottom, on the post. The gate half drops over it.
Will it rust?
It is bright bare steel, so paint it with the gate after welding. The rubbing faces stay oiled.
Does it work on both left and right hand gates?
Yes, it is the same either way.
