Custom-Developed Fastener Helps Protect American Troops

Improve Armored Vehicle Protection Explosives

When the US military determined that a type of armored vehicle needed improved protection from explosions in the field, a global manufacturer in defense and aerospace was contacted to develop a solution. 


Finding the right Mil-Spec Fastener Supplier

As a longtime Big Bolt customer, they called our team. We dove in to develop a dual internal/external shielding system fastener that's designed to meet the specific government contract military specifications.

“Nothing is more important than protecting soldiers in the field. When precision mattered, we connected with the Big Bolt team that quickly proposed options and we triangulated on a solution. Their fastener engineering expertise is unmatched. We were all fortunate to have them.” -Purchasing Manager, US Military


The resulting solution went into usage in combat situations overseas, made our customer shine as an industry-leading defense innovator, and most importantly, meaningfully reduced the potential impact of explosions in the field.
