Barrel bolt buying guide

What size barrel bolt do I need?

Bolt length and gauge should suit the door's weight and gap — longer, heavier bolts suit gates and external doors, while shorter bolts are fine for internal doors and cupboards.

Where are barrel bolts used?

They're ideal for sheds, gates, garages and double doors, and as an extra bolt on a front or back door. Fit a keep on the frame or floor for the bolt to slide into.

Necked or straight?

Straight bolts fit flat surfaces, while necked (cranked) bolts step the bolt over a rebate or raised edge so it lines up with the keep.

Which finish should I choose?

For outdoor use pick a corrosion-resistant finish such as galvanised, stainless or black; indoors, match your other ironmongery in chrome, nickel or brass.
