Product Description

Product Parameters

Welcome to our collection of high-quality bolts, perfect for a wide range of applications. Our screw-in back bolts are designed to provide secure and reliable fastening, ensuring your projects are built to last. Made from durable materials, these bolts are resistant to corrosion and wear, making them ideal for both indoor and outdoor use.

The screw-in back bolt consists of a conical expansion sleeve, a hexagonal screw and a flange locking anti-skid nut. During installation, the expansion sleeve is placed in the wedge-shaped hole, and then the screw is rotated to form a mechanical locking state, thereby achieving the purpose of fixing the plate. This back bolt is particularly suitable for thin plates.

The material of the screw-in back bolt is usually stainless steel, which has good seismic resistance and corrosion resistance. In addition, due to its simple structure and clear force, the screw-in back bolt requires high precision requirements during construction to ensure safety.

In practical applications, the screw-in back bolt is widely used in various construction projects. Its unique stress-free post-cut mechanical locking technology makes it perform well in seismic and wind load resistance, and has passed the relevant seismic tests of the National Engineering Quality Supervision and Inspection Center.

Whether you're working on a DIY project at home or need industrial-grade bolts for a large-scale construction job, our bolts are up to the task. With precise threading and a strong grip, you can trust our bolts to hold everything together securely. Shop with confidence knowing you're getting top-notch bolts that meet the highest standards of quality and performance.
