越南采购需求：地脚锚栓、螺钉蝶形螺母、螺钉和蝶形螺母、螺钉杯、长螺栓和螺母、套筒锚栓

We are looking for Expansion Anchor Bolts that have no markings or prints on the outer sleeve. Our research shows that in the China market, the printed size indicates the outer sleeve diameter, whereas in Vietnam, it refers to the internal bolt diameter. This discrepancy can lead to confusion in our applications. To avoid any misunderstandings, we specifically require products that do not include any such size prints on the outer sleeve. Please confirm your ability to provide this type of product, along with any relevant specifications. Thank you!
