Our company specializes in producing carbon steel grade 8.8 threaded screws, identifiable by the distinctive color associated with carbon steel. These screws adhere to the American standard B7 material and are primarily utilized as connecting parts located beneath finger racks. Widely employed in construction and decoration, they offer versatility across various applications. Ensuring optimal functionality, the threaded section's length is adjusted to expose the nut by 1-2 spacing units upon tightening. We also offer stainless steel variants in materials 304 and 316 to suit specific requirements. With a longstanding dedication to fastener production, our company boasts a professional testing department holding relevant certifications. Rigorous production management practices underscore our commitment to quality assurance, ensuring top-tier products. We specialize in customization, offering tailored solutions for non-standard parts based on customer requirements. Our team accommodates customer specifications, providing drawings aligned with their needs. Customers can expect secure transactions and count on us for establishing enduring partnerships built on trust and reliability for long-term cooperation.
