Import Anchor Bolts — Buy in Bulk from Supplier in China

L-shaped anchor bolts from Haiyan Haiyu Hardware Co., Ltd. are custom-engineered fasteners designed for structural anchoring in concrete or masonry. Each bolt is manufactured to customer specifications, with high tensile strength suitable for heavy-load applications and corrosion-resistant finishes to extend service life in harsh environments. The bolts are produced from industrial-grade carbon steel or alloy steel, ensuring consistent performance under dynamic stress.

Standard variants include hot-dip galvanized, stainless steel, or zinc-plated coatings to match environmental exposure levels, with typical thread sizes ranging from M8 to M36 and lengths from 50 mm to 600 mm. Industry practice allows for custom head configurations such as hex, square, or L-shaped bends, with typical tolerances for diameter and length following ISO 2768-mK for machined parts. These bolts are commonly paired with washers and nuts conforming to DIN 934 or ASTM A194 standards.

Primary buyers include construction contractors, infrastructure developers, and industrial machinery installers who require reliable anchoring for columns, bases, and equipment. Trade terms for this supplier are confirmed on request, with packaging typically in wooden crates or steel pallets to prevent damage during transit.
