Recommended for domestically produced stainless bolts! Stainless hex nuts with excellent cost performance.
Stainless steel can generate friction heat during tightening, causing the screw part to expand and potentially leading to the phenomenon of "seizing/binding." To address this issue, our product applies a fluoropolymer resin thoroughly to control the friction coefficient during tightening, thereby preventing the occurrence of seizing in bolt-nut engagements under normal conditions. Compared to domestic products, it offers excellent cost performance and does not reach the level of seizing even under conditions of repeated use up to five times. 【Features】 ■ All units selected from domestic manufacturers ■ Manufacturer's product warranty included (with engraving) ■ Superior cost performance compared to domestic products ■ Does not reach the level of seizing even under conditions of repeated use up to five times *For more details, please refer to the PDF document or feel free to contact us.
