Based on a survey, the bolts mounted on the outer shell of the helmet act as lethal secondary fragments that endanger the soldiers wearing it. In order to increase soldier's confidence, it should be ensured that the ideal ballistic helmet must be free from bolts to provide uniform protection all around the outers of the helmet shell.

Boltfree helmets from MKU feature a shell which is based on no-drill concept, that not only provides enhanced comfort but also increases protection against ballistic threats. These helmets are available in both PASGT and ACH configurations.

The 3 point harness system in the Boltfree helmets provides a snug fit to the soldiers and the spacious air ventilation reduces sweating. These helmets are capable of withstanding high speeds of FSP’s and can withstand Level III A bullets as specified by NIJ.
