Hex Bolts

Hex bolts have hexagonal heads (six-sided), machine threads, and typically used with a tapped hole and nut. The most common specifications include: ASTM A307A, A354, and F1554.

Hex head bolts can be partially threaded or fully threaded, which are commonly called tap bolts. They are manufactured by a hot-forging process and allow for a die seam across the bearing surface. If your application requires a thicker head, consider using a heavy hex bolt or structural bolt for structural steel-to-steel connections.

Hex Bolts vs Hex Cap Screws

Hex bolts are often mistakenly called hex cap screws, though the main difference is that hex cap screws feature a washer face under the head and a chamfered point, and a hex bolt does not have a washer face or chamfered threads. Hex cap screws are used in more precise applications like OEM where a tighter tolerance is required.
