A new kind of stainless alloy combines 410 hardened with a touch of 316 (molybdenum)

Marutex® means
1. High hardness for drilling
2. Far superior corrosion resistance

The Special Ingredient in Ultra Stainless™

Marutex® adds 2% molybdenum (moly) to 410 stainless.

Moly is the significant component of 316 stainless that provides extra corrosion resistance.

Now moly is added to 410 self drilling screws to produce Ultra Stainless™ providing unprecedented corrosion resistance combined with hardness for drilling.

Marutex® screws are tempered and quenched; regular T-410 self-drilling screws are case hardened. The additional carbon in Marutex® provides hardness for better drilling.
