Perma-Seal Neo/Bonded Sealing Washer - No. 10 x 5/8-in - Bag of 100

Seal Fastener Holes Against Leaks - Bag of 100

Screws driven through panels, covers or reservoirs can leave a path for water and humidity. A sealing washer sits under the fastener head and closes that gap. This Perma-Seal Neo/Bonded sealing washer is made for No. 10 x 5/8-in hardware, so you can seal each fastening point as you assemble.

One bag holds 100 washers. That suits a grower building or repairing benches, covers, enclosures or hydroponic system parts, and it gives a commercial crew enough to work through a run of fastening points.

Key Features & Benefits

• Sealing washer design — helps block moisture at the fastener hole.
• Neo/Bonded construction — pairs a sealing layer with the washer body so it stays in place under the screw head.
• No. 10 x 5/8-in size — matches common small-fastener assemblies.
• Bag of 100 — covers many fastening points in one order.

Who Should Use Perma-Seal Neo/Bonded Sealing Washer

Home gardeners building shelving or enclosures, and commercial growers maintaining greenhouse or indoor cultivation structures, can use these washers wherever a fastener passes through a surface that needs to stay watertight.
