High-performance fasteners known for their exceptional strength and resistance to corrosion, SS 316 Hex Bolts are made from premium-grade stainless steel metal 316 (AISI 316/EN 1.4401). These hex bolts are perfect for use in high-temperature settings, chemical processing, food preparation, and maritime applications. SS 316 is more resistant to pitting and crevice corrosion when molybdenum (Mo) is present, particularly in environments with a high concentration of chloride. Precision-engineered SS 316 Hex Bolts in a range of sizes, thread types, and finishes are manufactured and provided by Stainless Bolt Industries, guaranteeing strength, dependability, and longevity in every application.
Solid stainless- grade 316, which is used to make SS 316 Hex Bolts, is renowned for its remarkable resistance to heat, corrosion, and chemical exposure. Molybdenum (Mo) is added to SS 316 to improve its resistance to pitting and crevice corrosion, particularly in conditions that are rich in chloride and are found in maritime situations. For crucial applications in sectors including oil and gas, chemical processing, maritime engineering, food and beverage, and pharmaceuticals, these hex head bolts are perfect. Because of their exceptional mechanical qualities and long-lasting performance, SS 316 Hex Bolts are a reliable option for structural applications both indoors and outdoors.

The key difference lies in corrosion resistance. SS 316 contains molybdenum (Mo), which enhances its ability to resist chlorides, pitting, and crevice corrosion—making it ideal for marine, coastal, and chemical environments compared to SS 304.
SS 316 offers excellent corrosion resistance. While no metal is completely immune to corrosion under all conditions, SS 316 resists rusting far better than standard steel, especially in marine and chemical settings.
Absolutely. Their superior corrosion resistance makes them ideal for outdoor use, as well as submerged or saltwater applications such as docks, ships, and offshore platforms.
We offer SS 316 hex bolts in sizes ranging from M3 to M64 (metric) and from 1/8" to 2.5" (imperial), with custom sizes available upon request.
Yes. SS 316 hex bolts can withstand continuous exposure to temperatures up to 870°C (1600°F), making them suitable for high-heat environments like furnaces and boilers.
