Barrel Bolts

A barrel bolt is one of the most widely recognised and trusted pieces of door security hardware. Simple, robust, and easy to fit, it provides a secondary fastening on doors and gates that supplements or replaces a latch, and adds an additional layer of physical security at the point of entry. At the DIY Hardware Store, our barrel bolts range covers the standard cylindrical sliding bolt format in sizes and finishes suited to interior and exterior applications.

The barrel bolt consists of a cylindrical steel rod that slides within a barrel-shaped housing, engaging into a loop or keep plate fixed to the door frame. It operates entirely by hand with no key required, making it the go-to solution for securing shed doors, garden gate bolts, bathroom and bedroom doors requiring privacy fastening, and any door that needs a simple, visible, manually operated lock-off.

Available in a range of sizes from small decorative models for internal cabinet and cupboard use through to heavy-duty versions for solid timber gates and external doors. Finishes include bright zinc, galvanised (for exterior use), and ornamental options in black and brass for heritage or period properties.

Barrel bolts are quick to install with basic tools and give years of reliable service. Browse the full range at the DIY Hardware Store and find the right size and finish for your door or gate.
