Hook Bolt ALPAR S3024 M20 L‑350 Galvanized (ocynkowana)

ALPAR hook bolt S3024 M20 L‑350 Galvanized is a heavy‑duty threaded hook designed for secure anchoring and load transfer in construction and industrial settings. The bolt features an M20 thread and a 350 mm overall length, with a galvanized zinc coating that improves corrosion resistance and extends service life in exposed or humid environments. It is intended for situations where a robust hook connection is required to support structural elements, fixtures, or suspended loads.

Advantages

The galvanized finish provides enhanced resistance to rust and weathering compared with untreated steel, making the hook bolt suitable for outdoor and indoor applications. Its M20 thread size and substantial length allow for strong mechanical engagement and flexibility in installation depth. The hook form permits easy attachment of cables, chains, or other fittings while maintaining a reliable mechanical anchor when fixed into compatible substrates.

Suitable for

• Anchoring structural supports and steel frameworks
• Mounting fixtures, brackets and suspended equipment
• Securing cables, chains and light to medium suspended loads
• Use in construction, workshops, warehouses and industrial installations

When it may not be suitable

This hook bolt is a mechanical fastener intended for use with appropriate anchors or embedded fixings and is not a chemical anchor or adhesive solution. It may not be suitable where stainless corrosion resistance is required for highly aggressive environments or where electrical conductivity must be avoided. For critical load‑bearing applications, a structural engineer should verify suitability and load ratings for the chosen substrate and fixing method.

Key specifications

• Thread size: M20
• Overall length: 350 mm
• Finish: galvanized (zinc coated)
• Form: hook head for attachment of cables, chains or fittings
• Material: steel (galvanized surface treatment)

How to use

Install the hook bolt by drilling or preparing a compatible hole or anchor point in the chosen substrate, then insert and secure the bolt according to the selected anchoring method and manufacturer guidelines for the anchor system. Tighten to the recommended torque and verify that the hook orientation and engagement are correct before applying load. Regularly inspect installed bolts for corrosion, loosening or deformation and retighten or replace as necessary.

What to consider before purchase

• Confirm that M20 thread and 350 mm length match the mounting and embedment requirements
• Check substrate type and choose an appropriate anchor or fixing method for the hook bolt
• Assess environmental conditions to determine if galvanized protection is sufficient
• Verify load requirements and consult engineering specifications for safety margins

Usage recommendations

Use with compatible mechanical anchors or embedment systems rated for the intended load. For outdoor or corrosive environments where higher resistance is needed, consider alternative materials or coatings. Periodic inspection and maintenance will help ensure long service life and safe performance.
