Product Overview
Product Application
GB/T 22795 Expansion Anchors are mechanical fastening components specifically designed for secure installation in concrete. When tightened, the expansion sleeve expands against the wall of the drilled hole, creating a strong frictional and mechanical interlock capable of withstanding high tensile and shear loads.

Common Questions
What is a GB/T 22795 expansion anchor?
A mechanical anchor designed to create a secure connection in concrete through sleeve expansion.
What is the difference between a sleeve anchor and a wedge anchor?
A sleeve anchor expands along its sleeve for versatile applications, while a wedge anchor expands at the base for higher load capacity.
What material is best for outdoor expansion anchors?
SUS316 stainless steel offers the best corrosion resistance for outdoor and marine environments.
Can GB/T 22795 screws be customized?
Yes. Custom materials, sizes, coatings, and packaging are supported.
