The heads of the BYG hexagonal bolts are 20% higher than the American standard ANSI B 18.2.1 and that the norm DIN931 (ISO 4014) DIN933 (ISO 4017) DIN960 (ISO 8675) DIN961 (ISO8676), providing the BYG bolts with more capacity and wear resistance.
For greater strength and durability of the BYG fasteners, use them with BYG high-strength HD nuts and washers.
