Black yellow zinc HDG surface treatment DIN934 Hex Nuts

Hex nuts in metric Grade 8 and above are commonly considered as high tensile hex nuts. These nuts are made of medium carbon steel or alloy steel and have been quenched and tempered. As we fully realize the significance of heat treatment as an integral supplement to good quality forging, we introduce our own heat treatment furnaces. In addition, surface treatment lines are also built to satisfy different demands, such as finishes in black oxide, zinc plating, HDG and dacromet. So the quality of our fasteners can be guaranteed at every stage of the process and costs can be more competitive among our domestic exporters.
We offer a wide range of hex nuts in different materials and finishes to suit different applications. All our nuts are available in a variety of threads from Standard Metric Coarse Thread, Metric Fine, to Imperial and Unified Threads.
Besides, we will select the most suitable packaging to ensure the safe delivery of the hex nuts.
Decent quality, the best possible prices and on-time delivery make us establish a long term cooperation with more and more customers from our domestic and overseas customers.
