Crook Top Drop Bolt 20mm x 500mm, Forged End, Steel Bar for Gate Makers

A heavy 20mm drop bolt with a forged crook top, 500mm long. This is the heaviest of the crook top bolts we list: 20mm round steel bar, 500mm long, with a crook top bent over to form a handle that ends in a forged tip. It is the bolt to use on large or heavy gate leaves, where a thinner bolt would look undersized or bend. Eye guides and a hook are not included: order them separately to suit your gate. Plain steel, supplied ready to weld and finish with the gate. The price shown is for one bolt, with a minimum order of 5, because these are bought by gate makers for a batch of gates or larger sets.

Why this part works

Heavy 20mm bar. At about 2.2 kg, this bolt has real weight, and that matters on big leaves which need to be held down firmly.

Forged tip. The forged end gives the crook a finished, traditional look, and the shape is comfortable to lift.

Good length. At 500mm there is enough bolt to pass through two guides and reach the ground with room to spare, even on a gate with a higher bottom rail.

Finish it with the gate. Bare steel takes paint, powder coat or galvanising alongside the rest of the frame.

Where it is used

Large driveway and estate gates, heavy wrought iron gates, and agricultural or commercial gates where a smaller bolt would not stand up to the job. It is a fabricator's part and it needs welded eye guides on the stile, and a hole in firm ground for the bolt to drop into.

Specifications

Choosing the right option

Choose this bolt when the gate is large, heavy or subject to wind, because the 20mm bar gives you more strength than our 16mm and 12mm crook top bolts. If the gate is a typical domestic or light commercial gate, the 16mm bolt will be easier to work with and cost less. You will need 20mm eye guides, as a smaller eye will not let the bolt through.

Fitting and care

Close the gate and hold the bolt against the closing stile with the foot on the ground. Thread the two 20mm eye guides onto it and weld them to the stile, one close to the bottom rail and the other several hundred millimetres above it, in line so the bolt runs freely. Core a hole in the ground for the foot to drop into. Clean up the welds and paint or galvanise with the gate.

Keep the ground hole free of debris and grease the eye guides lightly on gates in regular use. Check the welds at each routine inspection of the gate.
