Stainless Steel Tam Anchor

We are producing stainless steel fish scale expansion bolts at Aojia Fasteners. These materials are made of high-quality and corrosion-resistant stainless steel. The stainless steel fish scale expansion bolt is a popular fastener that uses a fish scale shape on its expansion part to effectively improve fastening force and prevent loosening. The correct installation method is to place the expansion bolt into the hole and then rotate the nut to expand the expansion part outward and fix the material in place.
