Robust hexagon head bolt for reliable fastening

This hexagon head bolt with metric thread M4 and a length of 60 mm is made from grade 8.8 steel, providing high tensile strength and durability. The hexagonal head allows the bolt to be securely tightened with a standard wrench, which is essential for a safe and stable fastening.

Electrolytically galvanized finish for extra protection

The electrolytic galvanization offers excellent protection against corrosion, making this bolt suitable for use in humid environments or wherever extra protection against rust is desired. This extends the lifespan of the fastening and maintains the aesthetic quality of the end product.

Precise dimensions according to DIN 933 standard

• Diameter (d-D): M4
• Length (L): 60 mm
• Head height (k): 2.8 mm
• Wrench size (s): 7 mm
• Thread pitch (P): 0.7 mm

These specifications comply with the DIN 933 standard, ensuring consistency and compatibility with other DIN-standardized components.

Versatile use in various applications

Thanks to the combination of strength, corrosion resistance, and precise dimensions, this hexagon head bolt is ideal for use in:

• Automotive sector: Fastening of body and engine parts.
• Construction sector: Assembly of metal structures and frames.
• Mechanical engineering: Assembly of machines and equipment.

Important considerations when using

When using electrolytically galvanized bolts, it is important to consider the possibility of hydrogen embrittlement, especially in applications where high tensile loads occur. Ensure proper installation and avoid excessive loading to maintain the integrity of the fastening.
