M5 bolts

M5 bolts are used across a wide range of construction tasks, including assembling steel fixtures, fixing brackets, securing electrical boxes, and joining timber sections. Paired with nuts and washers, they offer reliable fastenings where a moderate load-bearing connection is needed. M5 refers to the 5mm thread diameter, making these bolts suitable for lighter applications than larger metric bolts.

You’ll find M5 bolts in several types, such as hex head, socket cap, and countersunk, with variations in length, thread pitch, and finish. Stainless steel and zinc-plated versions are widely used in both interior and exterior settings. Compared with M6 or M8 bolts, M5 bolts are easier to install in tight or delicate assemblies.
