M12x300 Hex Head Bolt Zinc Plated

• These high tensile hex head bolts are made from 8.8 grade steel.
• Bright zinc plated for protection against corrosion.
• The bolts are part threaded and conform to DIN931 standards.
• The hexagonal head has been designed for use with spanners or sockets and offers maximum torque when used with these tools.

APPLICATION:
For fastening together numerous types of material or to be fastened into pre-tapped holes. Widely used in many engineering applications.

Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity
