Product Description

Product Description & Key Specifications

Stainless L/J anchor bolts are supplied in SS304 / SS316 with A2-70 / A4-80 grade options for cast-in concrete foundations, exposed deck equipment, light structures and corrosion-resistant anchorage. DIN 529 references and OEM drawings are supported, with common project range from M12-M36.

Unlike post-installed wedge anchors, L/J anchor bolts are positioned before concrete placement so that the bent leg provides mechanical anchorage inside the foundation. Correct specification should confirm thread diameter, total length, thread length, bend radius, hook length, projection above concrete and template requirements.

SS304 / A2 suits general outdoor foundations, while SS316 / A4 is preferred for marine, coastal, water-treatment and chloride-exposed environments. Passivation improves stainless surface condition after forming and threading, and anchor bolt templates or nut-washer sets can be supplied for installation control.

Selection

Selection Advantages by Application

Construction Foundations

M16, M20, M24 and M30 stainless L/J anchor bolts are used for light steel columns, exposed base plates, railings and outdoor equipment foundations where corrosion resistance is required.

Construction fasteners

Marine Deck Equipment

SS316 / A4 anchor bolts are preferred for coastal or marine deck equipment foundations, bollards, brackets and stainless support frames. Confirm projection height and template layout.

Marine fasteners

Water Treatment Equipment Bases

Passivated SS316 L anchor bolts support pumps, skids and pipe supports in wet service. Common RFQs include M16 x 300, M20 x 400 and M24 x 500 with nuts and washers.

Water treatment fasteners

Renewable Outdoor Structures

Stainless cast-in anchor bolts can be used for selected outdoor renewable equipment bases where corrosion resistance and embedded anchorage are required. Confirm foundation design before procurement.

FAQ

Common Questions Before RFQ

What information is needed for stainless L/J anchor bolts?

Confirm diameter, total length, thread length, hook or leg length, bend radius, projection above concrete, material, finish, quantity and whether templates, nuts and washers are needed.

What is the difference between L anchor bolts and wedge anchors?

L/J anchor bolts are cast into concrete before placement, while wedge anchors are post-installed into drilled holes in existing concrete. The correct option depends on the foundation design and installation stage.

Should I choose SS304 or SS316 anchor bolts?

SS304 / A2 is suitable for general outdoor foundations. SS316 / A4 is preferred for marine, coastal, washdown, water-treatment or chloride-exposed environments.

What sizes are commonly requested?

Common RFQ models include M16 x 300, M20 x 400, M24 x 500, M30 x 600 and M36 x 800. Final dimensions should follow the foundation drawing.

Can anchor bolt templates be supplied?

Yes. Anchor bolt templates, nuts, washers and project tagging can be supplied when layout drawings and installation requirements are provided.
