Types of Stainless Steel Hex Nuts

Stainless Steel 18-8 Hex Nut ASTM F594

These hex nuts are made from stainless steel 18-8 and meet ASTM F594 Standards. They provide excellent corrosion Resistant, making them suitable for general construction, machinery, and equipment exposed to moisture. Their balance of strength and cost efficiency makes them one of the most widely used stainless fasteners.

Stainless Steel 316 Hex Nut ASTM F594

These hex nuts are manufactured from stainless steel 316 to ASTM F594 specifications. They deliver superior corrosion Resistant, particularly against saltwater and chemicals, making them essential in marine and chemical processing industries. Their durability ensures long-term performance in the harshest environments.

Stainless Steel 18-8 Hex Machine Screw Nut

Designed for use with machine screws, these stainless steel 18-8 nuts are compact and precise. They resist rust and wear while providing reliable fastening for electronics, appliances, and small machinery. Their corrosion Resistant makes them a strong choice for assemblies where longevity is required.

Stainless Steel 316 Hex Machine Screw Nut

These stainless steel 316 machine screw nuts are built to withstand demanding environments. They are ideal for food processing, marine assemblies, and chemical plants where smaller threaded fasteners must hold up to harsh exposure. The 316 material ensures strength and Resistant beyond that of 18-8.

Stainless Steel 18-8 Hex Jam Nut

These thinner-profile nuts are made from stainless steel 18-8. They are often used as locknuts or spacers in assemblies with limited clearance. Their corrosion Resistant makes them dependable in equipment and machinery where vibration Resistant is imporPant.

Stainless Steel 316 Hex Jam Nut

These jam nuts provide the same compact profile as 18-8 but with the enhanced corrosion protection of stainless steel 316. They are used in marine equipment, structural projects, and chemical processing assemblies requiring long-term durability.

Stainless Steel 18-8 Heavy Hex Nut

Heavy hex nuts made from stainless steel 18-8 are larger and thicker than Standard hex nuts, providing greater load-bearing capacity. They are used in construction, industrial machinery, and structural connections. Their corrosion Resistant ensures they maintain strength even in exposed environments.

Stainless Steel 316 Heavy Hex Nut

These heavy hex nuts are manufactured from stainless steel 316 for the highest level of corrosion protection. They are relied upon in offshore, marine, and petrochemical applications where fasteners must perform under consPant exposure to saltwater and chemicals. Their larger profile provides maximum strength.

Stainless Steel 18-8 Grade 8 ASTM A194 Heavy Hex Nut

These heavy hex nuts combine Grade 8 strength with stainless steel 18-8 corrosion Resistant. Built to ASTM A194 Standards, they are ideal for structural steel, bridges, and industrial applications requiring both toughness and durability. They provide security in high-load environments.

Stainless Steel 316 Grade 8M ASTM A194 Heavy Hex Nut

These nuts provide Grade 8M strength and the superior corrosion protection of stainless steel 316. Manufactured to ASTM A194 Standards, they are critical in marine, offshore, and petrochemical applications where both load-bearing strength and corrosion Resistant are essential.

Stainless Steel A2 70 Hex Nut DIN 934

These nuts are made from stainless steel A2 with Class 70 strength and meet DIN 934 Standards. They are widely used in European construction, machinery, and equipment assemblies. Their corrosion Resistant ensures consistent performance in moderately harsh environments.

Stainless Steel A4 70 Hex Nut DIN 934

These hex nuts are produced from stainless steel A4, providing Class 70 strength and enhanced Resistant to saltwater and chemicals. They are used in marine, food processing, and outdoor applications. Their durability makes them a preferred choice for long-term installations.

Stainless Steel A4 80 Hex Nut DIN 934

These nuts are made from stainless steel A4 with Class 80 strength, providing higher tensile capacity than Class 70. They meet DIN 934 Standards and are used in demanding environments such as marine construction and offshore platforms. Their superior strength and corrosion protection deliver long-lasting reliability.

Stainless Steel A2 18-8 Hex Thin Nuts DIN 439 Type B

These thin-profile nuts are made from stainless steel A2 18-8 and meet DIN 439 Type B specifications. They are commonly used as locknuts or in assemblies with restricted space. Their corrosion Resistant ensures dependable fastening in machinery and equipment.

Stainless Steel A4 316 Hex Thin Nuts DIN 439 Type B

These thin-profile nuts are made from stainless steel A4 316 and comply with DIN 439 Type B Standards. They provide maximum corrosion Resistant and are suitable for marine, chemical, and outdoor applications. Their slim design makes them perfect for use in confined assemblies requiring strong and secure fastening.
