M20x90 Hex Head Set Screw Galvanised

• These set screws are made from grade 8.8 steel.
• Galvanised for increased resistance to corrosion.
• They are fully threaded and conform to DIN 933 standards.
• Can be used with many nut types and washers.

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

Galvanised 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. Galvanising is a plating that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity as it is formed. The galvanising, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
