Sealing Washer #8 18-8 Stainless

The MIDWEST FASTENER CORP 53789 is a sealing washer designed for bolt size #8. Made from 18-8 stainless steel, it provides corrosion resistance and a reliable seal in automotive and general hardware applications. The component is supplied new and ships directly from the manufacturer.

Suitable Uses and Limitations

This washer suits installers who need a stainless sealing washer for #8 bolts in wet or outdoor environments. It is not for buyers who require a different bolt size, a different material grade, or an assortment containing multiple washer types.

Capacity and Headroom

The 18-8 stainless construction handles typical automotive and hardware sealing tasks where moderate corrosion resistance is needed. It runs out when the application demands a larger inner diameter, a thicker profile, or a higher-grade alloy for extreme chemical exposure.

Questions about this item

What bolt size must I already have for the 53789 sealing washer to fit?

The washer fits a #8 bolt, so you need that exact bolt diameter for a proper seal.

Will the 18-8 stainless steel washer corrode when paired with older carbon-steel fasteners?

18-8 stainless resists rust, but contact with carbon steel can cause galvanic corrosion in wet conditions; isolate the metals if moisture is present.

How can I verify the 53789 washer is sealing correctly after installation?

Pressurise the joint or run water over it; no leakage around the bolt hole means the washer is compressing and sealing as intended.
