Carbon Steel L Type Anchor Bolts 7 Shape Foundation Bolts DIN Grade 4.8 8.8 10.9 12.9

These L type anchor bolts are used where a threaded fastener needs to be embedded into concrete or foundation structures. The bent end creates mechanical anchoring after the concrete cures, while the threaded end remains exposed for fastening nuts, washers, base plates, brackets, columns, or equipment frames.

The product type is anchor bolt, suitable for foundation connection and heavy-duty installation work. Steel material provides strong fastening capacity and stable structural support. Carbon steel is commonly selected for construction and industrial anchoring because it offers practical strength, cost-effective supply, and good processing flexibility. Stainless steel can be selected when corrosion resistance or special environmental requirements are important.

Surface Treatment Options

Bright uncoated finish gives the anchor bolt a plain silver surface and is suitable for general foundation use, further processing, or applications where the buyer needs an untreated surface according to project requirements.

White zinc finish provides a clean zinc plated appearance and basic corrosion protection for storage, transport, and general construction hardware supply. It is suitable for indoor or controlled installation environments where a neat surface and practical rust resistance are required.

Yellow zinc finish can be selected for buyers who need a yellow passivated surface appearance for hardware markets, construction channels, or project identification.

HDG, also known as hot dip galvanizing, is suitable for outdoor foundation anchoring, humid environments, exposed steel structures, and construction projects where stronger corrosion resistance is needed. HDG coating helps protect carbon steel anchor bolts during storage, transport, and long-term installation.

Application

These L type anchor bolts and 7 shape foundation bolts are suitable for concrete foundations, steel column bases, machinery bases, equipment installation, building construction, warehouse structures, guardrail supports, solar mounting systems, pipe supports, industrial frames, and infrastructure projects.

For construction projects, the L-shaped or 7-shaped bent end helps anchor the bolt into concrete, while the threaded end can be used with nuts and washers to fasten the connected part. This makes the product suitable for embedded installation before concrete curing or for customized foundation fastening systems designed by drawings.

The product can serve contractors, steel structure fabricators, machinery factories, construction hardware distributors, infrastructure suppliers, and fastener wholesalers that need bulk anchor bolt supply in inch or metric sizes.
