Zinc Finish Serrated Hex Flange Nuts DIN 6923 M5 To M20 Class 8

Metric Medium-Strength Steel Serrated Flange Locknuts—Class 8

Product Description:

Flange nuts have a washer like base to distribute pressure over a greater surface area and ensure the fastener stay tight.They are commonly used in manufacturing assembly lines where operations are speeded by using a single fastener instead of a nut and washer.

Product Features:

Strong enough for use in most machinery and equipment, these medium-strength metric nuts have serrations on the underside of the flange. The serrations prevent the nuts from loosening in applications with mild vibration.

Also known as collar nuts, they do not require a washer, which saves assembly time. Instead, the flange spreads the holding force across a wide area. Because the flange makes them wider than standard nuts, they may not fit into tight spots.

Zinc-plated steel nuts have a layer of zinc on the outside that prevents the steel from rusting in wet environments, extending the life of the nut.

To ensure compatibility with other parts and tools, some nuts meet ISO 4161 (formerly DIN 6923).
