2026 witnesses continuous technological iteration and performance optimization in the fastener industry, with breakthroughs in material improvement, structural design and anti-loosening technology for expansion bolts, screws, bolts and nuts, greatly expanding their application boundaries in high-end engineering and precision manufacturing fields. Traditional fastener products are gradually upgrading to high-strength, corrosion-resistant, anti-fatigue and intelligent anti-loosening types, meeting the extreme working condition requirements of aerospace, marine engineering, high-speed rail and intelligent equipment.

In the field of expansion bolts, the new-generation integrated anchoring structure has solved the problems of insufficient bearing capacity and easy loosening of traditional expansion structures. The optimized wall-thickened expansion tube and tooth-shaped locking design significantly improve the anchoring stability in concrete, brick and stone base materials, and the product tensile strength and shear resistance are increased by more than 20% compared with traditional products. This upgraded expansion bolt is widely used in large-scale engineering anchoring, mechanical equipment fixing and building renovation projects, effectively improving the safety and durability of engineering installations.

For standard screws, bolts and nut supporting products, anti-loosening structural innovation has become a key technological hotspot. The improved self-locking thread structure and anti-backlash matching design effectively avoid loosening and failure caused by long-term vibration, high temperature and alternating load. In addition, the industry has continuously promoted the application of new alloy materials and surface treatment processes such as hot-dip galvanizing and stainless steel passivation, which greatly enhance the corrosion resistance and service life of fasteners in humid, high-salt and extreme temperature environments. The continuous technological upgrade has accelerated the elimination of low-performance backward products and promoted the high-quality development of the entire fastener industry.
