Abstract
A new bolt head design is disclosed and claimed. The bolt head has a radius between the shaft and the first side of a washer which spreads the shaft load more evenly to the washer. A concave dome is located between the second side of the washer and the driver of the head. These elements more evenly distribute the load, increase the bolt head strength and help prevent the washer, shaft and washer driver interfaces from failing when the bolt is loaded either in a linear or non-linear fashion.
