VDI 5.45 bolts are compatible with mil-spec and non mil-spec carriers. This bolt is machined from C-158 to exceed all MIL TDP specifications and is enhanced using LifeCoat® treatment providing superior:

• Durability
• Lubricity
• Corrosive Resistance

LifeCoat is more than just an application or coating processes. It is the most technologically advanced coating processes, material and machining available on the market today. LifeCoat is the idea that certain processes and materials are superior for their applicable needs and when combined they offer efficiencies unparalleled to anything currently available.

There are numerous amounts of coating process available on the market today claiming to be “the best”; some are baths that can do blind holes while others are strictly line of sight applications. Some of these coatings have little to no tolerance buildup and are considered molecular/permeated processes. Some coatings are best for lubricity while others fill the need for surface hardness or corrosion resistance. This isn’t just about coating processes, it’s also the most technologically advanced machining capabilities and material applications. This allows us to be the first company to provide a lifetime warranty on all VDI components.

Our years of R&D as well as beta testing have developed recipes that only experience can achieve. As innovators of design and product development all VDI’s unique products utilize the best possible formulas for ultimate performance and reliability. Take the challenge, upgrade your jalopy and welcome to the revolution!
