Washer, Galvanized Steel

Product Details

How do I check the washer size is right for my bolt or screw?

This Washer D6.4/18x1.6mm is designed for an internal diameter of 6.4 mm and an external diameter of 18 mm, with a thickness of 1.6 mm. If your bolt shank measures around 6.4 mm at the washer contact point, this size is a good match. Using the correct internal diameter helps ensure a secure fit and proper load distribution.

Is this washer suitable for general steel fixing applications?

Yes. The Washer D6.4/18x1.6mm is made from steel and is zinc plated, which is commonly used to improve resistance to corrosion in indoor and many outdoor environments. It is a practical choice for clamping tasks such as mounting brackets, securing panels, and other typical fixing jobs where a larger contact area helps.

What standards does this washer meet?

These washers comply with DIN EN ISO 7093 and DIN 9021. Meeting recognised standards helps ensure consistent dimensions and performance, making it easier to match parts across projects and replacements.

Will the zinc plated finish hold up against rust?

The zinc plated finish provides corrosion resistance, which helps protect the steel washer during normal use. For applications exposed to heavy moisture, salt air, or harsh chemicals, you may want to consider a more specialised protection approach, but for many everyday fixing and workshop uses, zinc plating is a reliable choice.

How many washers are included in the pack?

This product comes as a 250 pack, which is useful if you are stocking up for ongoing maintenance, repeat jobs, or larger installation tasks. Buying in bulk can also help reduce the need for frequent re orders.

Why choose a washer thickness of 1.6 mm for a connection?

A thickness of 1.6 mm can provide the right spacing and bearing surface for many assemblies. Using a washer of the correct thickness helps improve load spreading, reduces the risk of damage to softer surfaces, and supports more consistent tightening results.
