ASTM A194
- 2H & 2HM – High-strength options for structural and industrial applications
- Grade 7 & Grade 7L – Ideal for low-temperature and cryogenic applications
- Grade 8 & Grade 8M – Corrosion-resistant stainless steel options for marine and extreme environments
- GI (Electro Galvanized) – Provides basic rust protection
- HDG (Hot Dip Galvanized) – Offers superior corrosion resistance for outdoor environments
- Black (Self-Color) – Maintains the natural metal finish
- PPTF (Polytetrafluoroethylene) – Enhances wear resistance and reduces friction
- Cadmium Plating – Ensures exceptional corrosion resistance, widely used in marine and aerospace applications
- Yellow Zinc Plating – Enhances rust resistance and aesthetic appeal
The Hex Nut, also known as the Heavy Hexagonal Nut, is a crucial fastener designed with internal threading to securely fasten onto a bolt shank. ASTM A194 Heavy Hex Nuts are commonly paired with mating bolts to create a strong, stable connection between multiple components. The friction and compression generated by the internal threads ensure tight and long-lasting fastening, making them ideal for high-pressure and high-temperature applications.
Key Features
- Strong internal threads for a secure grip on bolts
- Designed to resist loosening due to vibration and heavy loads
- Manufactured as per ASTM, AISI, BS, EN, ISO, DIN, and JIS standards
- Available in multiple strength grades and protective coatings
