Bolts

Bolts are the backbone of countless construction, engineering, and DIY fixing applications. At the DIY Hardware Store, our bolts range covers the most widely used bolt types in sizes, grades, and finishes suited to everything from furniture assembly to structural timber connections and outdoor metalwork.

The range includes hex head bolts (the standard workhorse fastener for general structural and engineering use), cup square bolts (coach bolts, with a domed head and square shoulder that locks into timber), roofing bolts, U-bolts, and more specialist types for specific applications. Paired with the correct nut and washer, a bolt creates a secure, removable connection that can be tightened to load and replaced when worn.

Bolt selection depends on the load being carried, the environment (internal, external sheltered, or fully exposed), and the materials being joined. Zinc-plated bolts suit most internal and sheltered external uses; hot-dip galvanised provides enhanced protection for exposed outdoor applications; stainless steel is the choice wherever corrosion resistance is paramount.

Whether you're building a garden structure, fitting gate hardware, assembling steel framework, or working on a joinery project, the DIY Hardware Store has the bolt specification you need in stock.
