High Quality J Type Anchor Bolts M20 M24 M30 Galvanized Steel Foundation Bolts

These J type anchor bolts are used when a threaded fastener needs to be embedded into concrete foundations or structural bases. The J-shaped hooked end helps improve anchoring after concrete curing, while the threaded end remains exposed for fastening nuts, washers, base plates, brackets, columns, or equipment feet.

The product is suitable for concrete, metal, plaster, panel, and general construction fastening applications. It is commonly used in steel structures, machinery foundations, building columns, equipment bases, warehouse frames, road facilities, solar mounting support systems, guardrail posts, pipe supports, and industrial installation projects.

The material is steel, and the listed product description focuses on high quality carbon steel anchor bolts in different types. Steel anchor bolts are widely used because they provide practical strength, reliable embedding performance, and cost-effective bulk supply for construction and industrial projects. The listed capacity is 800, and the fastener type is bolt.

Available grades include 4.8, 8.8, 10.9, and 12.9. Grade 4.8 is suitable for general foundation anchoring and light to medium-duty fastening. Grade 8.8 is commonly selected for stronger steel structure and machinery base installation. Grade 10.9 and 12.9 can be used for higher-strength applications where the connected parts, installation torque, nut grade, washer type, and project load are properly matched.

The available diameter range includes M8, M10, M12, M16, M20, M30, and up to M100. The listed model range is M8-128, and the thread size includes M10. Length can be supplied from 100mm to 1000mm, supporting different concrete embedding depths and foundation thickness requirements.

Surface Treatment Options

Galvanized finish provides practical surface protection for anchor bolts used in construction, equipment installation, warehouse storage, and general foundation fastening. It helps reduce surface oxidation during transportation, storage, and normal use.

Plain finish can be selected when the anchor bolt will receive additional surface treatment, be embedded in controlled conditions, or be supplied according to a project’s own coating specification.

PZ finish is suitable for buyers who require zinc plated anchor bolts with a clean surface appearance and basic corrosion protection. It is commonly used for construction hardware and industrial fastening channels.

HDG, also known as hot dip galvanized finish, is suitable for outdoor foundations, steel structure projects, humid environments, and infrastructure applications where stronger corrosion resistance is needed. HDG coating is often selected for anchor bolts exposed to weather, long storage cycles, or demanding installation environments.

Bright uncoated finish is suitable when a clean uncoated surface is required for further processing or project-specific surface handling.

Application

These J type anchor bolts are suitable for concrete foundations, steel column bases, machinery bases, industrial equipment installation, warehouse structures, bridge and road support systems, guardrail support posts, construction brackets, solar mounting foundations, pipe supports, embedded metal plates, and heavy-duty fastening work.

For embedded installation, the J-shaped end is placed into the concrete foundation, while the threaded section remains above the surface. After the concrete cures, nuts and washers can be used to fasten base plates, support brackets, and equipment components. This makes J anchor bolts a practical choice for projects requiring stable foundation anchoring and easy top-side assembly.

The product can serve construction contractors, steel structure companies, machinery factories, infrastructure suppliers, fastener distributors, and project buyers who need bulk anchor bolt supply in M20, M24, M30, and customized diameters or lengths.
