■ ArmorMax: Enhanced Durability with Ultra-Hard Surface Treatment Our proprietary ArmorMax features a specially developed ultra-hard surface treatment. With a high-strength surface finish, it is resistant to scratches, wear, and corrosion, making it a "bolt tensioner with significantly improved durability." ■ Improved Fatigue Strength with ArmorMax Protection Metal fatigue, which occurs when repeated loads cause tiny scratches on the metal surface that lead to crack propagation, reduces lifespan. ArmorMax protection retains compressive surface stress that counteracts this, significantly increasing fatigue strength and providing crack suppression for a longer lifespan. ■ Enhanced Wear Resistance ArmorMax is treated with an ultra-hard surface that is resistant to scratches and marks. With high surface hardness and low friction coefficient, it not only improves wear resistance and fatigue strength but also reduces sliding wear, preventing damage to bolt tensioners and hydraulic nuts, thus extending their lifespan. ■ Improved Corrosion Resistance In neutral salt spray tests for corrosion resistance (over 800 hours), ArmorMax demonstrates superior corrosion resistance compared to other metal surface treatments like zinc plating and nickel plating, offering more than three times the rust prevention effect of standard black oxide treated bolt tensioners and hydraulic nuts.
