Stainless Steel Hexagonal Nuts are an adaptable fastener suitable for many different uses, typically chosen due to their corrosion resistance in harsh environments. While standard stainless steel nuts cannot provide the same level of strength as carbon steel bolts and screws do, premium BUMAX hexagonal nuts offer both corrosion protection and strength for more challenging applications.
Norway-based customer recently required hex nuts to secure new road signs. Since their sign masts are intended to break under heavy impact from vehicles, their fasteners must withstand considerable amounts of stress. After testing several types of fasteners and opting for two 109 Stainless Steel Hexagonal Nuts due to their strength and corrosion resistance.
BUMAX provides stainless steel hex nuts to meet most requirements, such as DIN 934 Hexagonal Nuts. Constructed using cold-worked stainless steel with exceptional ductility and corrosion resistance properties compared to other classes of alloys, Grade A2-70 (often known as 18-8 stainless steel) these cold worked hex nuts can elongate over time without losing their dimensional stability or hardness, yet still maintain tensile strength without losing tensile strength over time.
These hexagonal nuts are designed for use with hex-headed bolts and screws, featuring six-sided hexagonal bodies which can be tightened using a spanner or wrench. Hex nuts are easy to tighten or loosen and come in various sizes - the A2-70 graded stainless steel used in their production makes for lasting corrosion protection, perfect for many applications.
Hex nuts come in various sizes and thread types, from metric to imperial threading as well as UNC and UNF threading, making them suitable for production across a range of material categories and ASTM specifications. Furthermore, these nuts can also be coated with zinc plating or galvanizing finishes which provide corrosion resistance even in harsh environments; although this option comes at a premium.
These hex nuts are designed to connect two female threaded parts together for coupling purposes, such as tubular components. With both inch and metric threads on one side and tightenable by standard wrench, these nuts feature an irregularly shaped thread which grips tightly to resist loosening from vibration. Crafted from 18-8 stainless steel they may even be slightly magnetic.
