Marine Fasteners

<h3>About Marine Fasteners</h3><p>For decades, <strong>Marine Fasteners</strong> has built its reputation on a straightforward promise: stock quality hardware, keep plenty of it on the shelf, and back every order with knowledgeable customer service. Recognized as America's leading supplier of marine, solar, and industrial fasteners, the company has followed this philosophy since 1975. That long track record of reliability has made Marine Fasteners a go-to source for boatbuilders, solar installers, contractors, and industrial maintenance crews alike.</p><h3>A Specialist in Corrosion-Resistant Hardware</h3><p>What sets Marine Fasteners apart is its deep focus on materials engineered to survive punishing environments. The brand carries a full line of 304 and 316 stainless steel bolts, socket products, screws, nuts, washers, pins, and specialty fasteners, and also offers multiple secondary processes along with a proprietary line of chrome-plated inventory. This breadth of material options means customers can match the exact alloy grade to their application — whether that's a saltwater-exposed through-bolt on a boat deck or a structural anchor in a solar panel array.</p><p>With more than 35 years of thriving in demanding conditions and a team boasting over 700 years of combined experience, Marine Fasteners understands the nuances of stainless steel fastener requirements across a wide range of industries. That institutional knowledge translates directly into better product selection guidance and fewer costly specification mistakes.</p><h3>A Comprehensive Catalog Under One Roof</h3><p>The Marine Fasteners catalog spans an impressive range of hardware categories. Core product lines include bolts, nuts, screws and threaded products, washers, U-bolts, anchors, socket products, cable ties, rivets, rods and studs, snaps, hose cable and cushion clamps, clips and retaining rings, drill bits, pins, driver bits, hex keys, and kits and assortments. This single-source approach simplifies procurement for professionals who need a wide variety of fastener types without juggling multiple suppliers.</p><p>The brand also distributes specialty sub-lines to meet niche demands. The <strong>Fasco Fastener</strong> division — a proprietary Marine Fasteners line — covers packaged cable ties, packaged chrome fasteners, packaged cushion clamps, and packaged hose clamps, making it easy for retailers and distributors to merchandise pre-packaged hardware. For self-drilling applications, Marine Fasteners stocks the <strong>Elco</strong> product line, which includes 18-8 and bi-metal steel self-drilling screws in a range of diameters and lengths with Stalgard finish for superior corrosion protection.</p><h3>Materials Built for the Elements</h3><p>Choosing the right fastener material is critical in marine and outdoor environments. Stainless steel grades such as AISI 304 and AISI 316 are common choices due to their strength and corrosion resistance, with 316 offering superior resistance to chlorides found in seawater and deck hardware exposed to spray. Marine Fasteners stocks both grades across its full product range, along with silicon bronze, brass, nylon, aluminum, and hot-dip galvanized options to suit every substrate and exposure level.</p><p>Whether you're sourcing a few hundred bolts for a dock repair or placing a large industrial order for a manufacturing facility, Marine Fasteners has the inventory depth, material expertise, and product variety to get the job done right.</p>

Product Details

Marine Fasteners RP-6699 is a #10 fender washer made from 18-8 stainless steel, engineered for reliable fastening in marine, industrial, and outdoor environments. With a disproportionately large outer diameter relative to the inner bore, fender washers provide a significantly wider bearing surface than standard flat washers, helping to distribute clamping load and prevent fastener pull-through on thin or soft substrates.

Key Specifications:

  • Screw Size: #10
  • Inner Diameter (ID): 0.203 in
  • Outer Diameter (OD): 0.687 in (11/16 in)
  • Thickness: 0.050 in
  • Material: 18-8 Stainless Steel
  • Finish: Passivated Stainless (natural)
  • Quantity: 100 pieces per bag

Key Features:

  • 18-8 stainless steel construction delivers excellent corrosion resistance in saltwater, humid, and chemically exposed environments
  • Large OD-to-ID ratio distributes clamping forces over a wider area, preventing pull-through on fiberglass, wood, and thin sheet metal
  • Consistent 0.050 in thickness ensures uniform load distribution across fastened surfaces
  • Suitable for use with #10 screws, bolts, and machine fasteners in marine, RV, automotive, and construction applications
  • Sold in a convenient 100-piece bag for jobsite and shop use

These fender washers are cross-referenced as item F-010NFDWS-6699 and WFESS10-11/16 in the Marine Fasteners catalog, making them easy to source as a direct replacement or upgrade from standard flat washers.
