Stainless Steel Countersunk Washer Pack

This pack contains ten 18-8 stainless steel countersunk washers designed for use with Acorn wash fountains. The washers provide a flush finish when installed with compatible countersunk screws. They resist corrosion in wet environments typical of drinking fountain installations. The pack suits maintenance teams and installers servicing compatible units.

Replaces Worn Washers On Acorn Fountains

These washers replace original hardware on specific Acorn models including the 3402, 3423, 3424, 3506, 3508, 3543, 3544 and 3563 series. The upgrade is worth it when existing washers show corrosion, deformation or loss of clamping force. Using the correct 18-8 alloy prevents galvanic issues with stainless fountain bodies. They also match Grainger part numbers 10A312 through 10A325 for cross-reference ordering.

Limited To Countersunk Screw Applications

The countersunk profile only works with matching flat-head screws that sit flush in the washer. They cannot be used with pan, button or hex head fasteners without leaving a gap. The 18-8 stainless material is not suited for highly chlorinated or marine splash zones where 316 grade is specified. Buyers needing washers for non-Acorn equipment or different screw styles should verify compatibility before purchase.

Questions about this item

What size screw or bolt does the #10 countersunk washer fit?

The #10 designation matches a number-10 machine screw or bolt, so the washer seats under a #10 countersunk head.

How do I install the Acorn 0336-004-001 washer on an Acorn wash fountain?

Place the washer under the #10 countersunk screw head with the tapered side facing the screw, then tighten until the head sits flush; the step often missed is aligning the taper before final torque.

When should I replace these 18-8 stainless steel washers?

Replace them if you see pitting, deformation, or loss of spring tension during routine fountain maintenance, especially in high-chloride water.
