Our company specializes in manufacturing carbon steel grade 8.8 threaded screws, characterized by the typical color of carbon steel. Additionally, we offer American standard B7 material, commonly used for connecting parts under finger racks. These screws find versatile applications in construction, decoration, and other assembly purposes.
Typically, the length of the threaded section is adjusted to ensure that, after tightening, the nut is exposed by 1-2 spacing lengths. We provide stainless steel variants in materials 304 and 316.
With years of dedicated experience in fastener production, our company boasts a professional testing department equipped with relevant certifications. Our stringent production management ensures top-quality products and guaranteed performance. We offer customization services for non-standard parts tailored to meet specific customer requirements. Moreover, we accommodate customization requests based on customer needs, providing drawings to match their specifications.
We prioritize safe and reliable purchases, fostering long-term partnerships built on mutual trust and satisfaction.
