: These have a hexagonal head and are easily tightened with a wrench. They are the standard for construction, machinery, and automotive projects.
Selecting the right bolt depends on the materials being joined and the required strength.
: Featuring a smooth, rounded head and a square neck to prevent rotation during installation, these are ideal for wood-to-wood or wood-to-metal projects like fencing and decking.
Bolts are externally threaded fasteners that create a strong clamping force (preload) to hold components together, typically requiring a matching nut or a pre-tapped hole. They are essential for applications ranging from furniture assembly to heavy-duty structural engineering. Common Bolt Types & Their Uses
: These heavy-duty bolts have coarse threads designed to screw directly into wood without a nut, providing high holding power for decks and heavy timber structures.
: Used where space is limited, these have a low-profile head and are tightened with an Allen (hex) wrench.
