Import Din22795 Expansion Anchors — Buy in Bulk from Supplier in China

DIN22795 expansion anchors are mechanical fasteners designed for anchoring into concrete and masonry substrates, manufactured in carbon steel, alloy steel, or stainless steel. These anchors expand radially when a bolt is tightened, creating a secure hold in drilled holes. The product line includes sizes from M6 to M24, with thread types matching DIN 13 metric standards and mechanical grades ranging from 4.8 to 12.9.

Typical industry specifications for DIN22795 anchors include a conical expansion sleeve with a split body that deforms under bolt tension. The standard requires a minimum pull-out resistance of 8 kN for M12 anchors in C20/25 concrete. Surface finishes include plain, zinc plated (clear, blue, yellow, black), black oxide, nickel, chrome, and hot-dip galvanized. The zinc plating thickness typically ranges from 5 to 15 microns, depending on finish type.

These anchors are widely used in structural steel erection, wind turbine towers, oil and gas piping supports, and heavy machinery mounting. Buyers include construction contractors, industrial equipment installers, and infrastructure firms in Europe, North America, and Southeast Asia. Packaging is in 25 kg cartons on wood pallets, with bulk orders accepted. Trade terms include FOB, CIF, CFR, EXW, DDU, and DDP, with lead times typically 30 - 45 days after order confirmation.
