Marine‑Grade Hardware: The Advantages of 316 Stainless Steel
From salty coastlines to chemical plants, A4 / 316 stainless steel is the gold standard for corrosion‑critical applications. While many suppliers stick with lower‑cost 304 or 18‑8 alloys, Monster Bolts makes 316 our first choice across screws, nuts, bolts, washers, lag bolts, and anchors. The secret? Extra molybdenum that blocks pitting, crevice corrosion, and chloride attack—exactly what harsh environments throw at you.
Why 316 Stainless Outperforms 304 & 18‑8
- Enhanced Corrosion Resistance – excels in salt spray, acidic runoff, & industrial chemicals.
- Longevity – fewer replacements mean lower lifetime cost for docks, coastal buildings, and food‑grade systems.
- Heat & Cryo Stability – maintains strength from ‑150 °F to 1500 °F.
The same molybdenum that makes 316 stainless tough against rust also makes it tougher on drills and taps—why precision 316 hardware costs more and lasts longer.

Machining 316: A Tough Metal with Tougher Benefits
Yes—316 is harder to cut, requiring slower feeds and premium tooling. But that density translates into higher tensile strength, better galling resistance, and hardware that simply lasts longer once installed.
