Hex bolts are six-sided bolts made of low-carbon steel and frequently used in construction and repair applications. A few of the most common specifications include: ASTM A307A, A354, and F1554. Hex bolts can be partially threaded or fully threaded, which are more commonly referred to as a tap bolt. They are typically 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. We also carry Grade 8 hex bolts.

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.
