We fabricate a wide variety of Stainless steel Hexagon Nut Types with coarse thread density. We also offer the best quality Heavy Duty Hex Nuts and Stainless Flange Nuts that are in compliance with international standards. These nuts are often made from steel of high strength material like high strength alloy steel, often used in general-purpose applications requiring both corrosion resistance and high strength.
Stainless Steel fasteners application Stainless steel is the material of choice for external applications and environments where corrosion is a factor. Most of Hebei Hanwang stainless steel fasteners are available in the standard grade of A2 stainless steel to suit the majority of requirements. For applications located in marine environments where salt water corrosion is a concern, many of our stainless fastener are also available in A2 and A4 stainless steel. In addition to this, some stainless steel fasteners are available in specific tensile strengths including A2-50, A2-70, ,A4-50, A4-70. for further information. please contact Hebei Hanwang sales apartment. Quality Control of Heibei Hanwang Fasteners Hanwang Fasteners operate a fully controlled quality system maintaining traceability of products from their initial source of supply, into stock, directly through to dispatch to the customer. For that Hebei Hanwang Fasteners established a fully functioning quality control lab and a active quality control office with quality-enthusiasm crew members. Heibei Hanwang Fasteners Testing Facility To check that the products we supply conform to the relevant standards and specific requirements of customers, Heibei Hanwang Fasteners operate specialist inspection equipment such as:- Tensile Machine for pulling kinds of Bolts / nuts
- Hardness Machine (portable and lab)
- Spectrum detection and metallography detection equipment
- Suitability Test Machine for assembly testing
- Both Rockwell hardness and Brinell Testing Machine
- Thread Gauges for bolts and nuts
- Plating Thickness Tester
