Seachoice

<h3>About Seachoice: Built by Boaters, for Boaters</h3><p><strong>Seachoice</strong> has been one of the most trusted names in the marine industry since its founding in 1988. What started as a focused supplier of marine hardware — cleats, hinges, and hasps — has grown into a comprehensive resource for boating enthusiasts of every level. Today, Seachoice offers more than 5,000 high-quality marine parts and accessories across 17 categories, backed by distribution from 18 warehouse locations for fast, reliable availability wherever you are on the water.</p><p>The philosophy behind Seachoice is straightforward: deliver the products boaters actually need, at a quality level they can depend on, without breaking the bank. That commitment has made Seachoice a go-to brand for both weekend recreational boaters and serious on-water professionals alike. Every product in the lineup is covered by a no-hassle warranty, reflecting the brand&quot;s confidence in its own craftsmanship.</p><h3>Anchoring Solutions for Every Vessel</h3><p>Anchoring is arguably the most critical system on any boat, and Seachoice has built an extensive anchoring ecosystem to match. Their <a href="/7548-seachoice-anchors-200101">Anchors</a> lineup includes a wide variety of styles suited to different bottom types and vessel sizes — from lightweight folding grapnel anchors ideal for personal watercraft to hot-dipped galvanized plow anchors engineered for boats in the 24-to-31-foot range. For boaters who need a permanent or semi-permanent solution, Seachoice&quot;s <a href="/7548-seachoice-mooring-anchors-200693">Mooring Anchors</a> are cast from heavy iron and sized for vessels from small runabouts all the way up to large cruisers, with improved shaft designs and oversized eyes to accommodate heavy-duty shackles.</p><p>For those who prefer traditional styles, the <a href="/7548-seachoice-slip-ring-traditional-anchors-200970">Slip Ring &amp; Traditional Anchors</a> collection offers classic navy and river anchor designs, many featuring vinyl or PVC coating for corrosion resistance in both fresh and saltwater environments. Whether you&quot;re anchoring in sand, gravel, shale, or soft mud, Seachoice has an anchor engineered for the job.</p><h3>Marine Rope and Cordage</h3><p>No anchoring system is complete without reliable cordage, and Seachoice&quot;s <a href="/7548-seachoice-rope-17207">Rope</a> category delivers just that. From solid-braid nylon dock lines that are rot-proof and abrasion-resistant to hollow-braid polypropylene anchor lines for smaller boats and PWC applications, Seachoice rope products are built for the demanding conditions of the marine environment. UV protection and corrosion-resistant hardware are standard features across the lineup, ensuring longevity whether you&quot;re in freshwater lakes or open saltwater.</p><h3>On-the-Water Comfort: Coolers &amp; Ice Chests</h3><p>A great day on the water also means keeping food and drinks cold, and Seachoice&quot;s <a href="/7548-seachoice-coolersice-chests-200288">Coolers/Ice Chests</a> round out the brand&quot;s on-board comfort offerings. Designed with the marine environment in mind, these coolers are built to handle sun, spray, and the rigors of life aboard a boat.</p><h3>A Brand You Can Count On</h3><p>Seachoice operates with a simple promise: quality you can trust, backed by worry-free protection. With a product line that spans lighting, electrical components, safety gear, hardware, anchoring, and more, Seachoice continues to be the brand boaters reach for when reliability matters most.</p>

Product Details

The Seachoice RP-SC1337 is a 3/8-16 nylon insert locknut constructed from corrosion-resistant stainless steel, ideal for marine and outdoor applications. This locknut features a nylon insert that creates friction against the threads, preventing loosening due to vibration and ensuring a secure, long-lasting connection.

Key Features:

  • Thread size: 3/8-16 (3/8 inch diameter, 16 threads per inch)
  • Stainless steel construction resists rust and corrosion in marine environments
  • Nylon insert provides self-locking action without requiring additional locking devices
  • Reusable design maintains locking effectiveness through multiple installations
  • Suitable for boats, marine equipment, trailers, and outdoor hardware applications

These locknuts are commonly used in applications where fastener security is critical, particularly in marine settings where saltwater exposure and constant vibration can compromise standard nuts. The nylon insert grips bolt threads firmly while still allowing for hand-starting and removal with standard tools.
