<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-SC30087 is a marine-grade hex cap screw manufactured from premium 316 stainless steel for superior corrosion resistance in harsh saltwater environments. This fastener features 5/16"-18 threading and measures 3-1/2" in length, making it ideal for heavy-duty marine applications where strength and durability are critical.

Key Features:

  • 316 stainless steel construction offers excellent resistance to saltwater corrosion and pitting
  • Hex head design allows for high-torque installation with standard wrenches or sockets
  • 5/16"-18 thread size provides strong holding power for structural connections
  • 3-1/2" length suitable for through-bolting and thick material applications
  • Marine-grade quality meets demanding boating and marine equipment standards

This hex cap screw is commonly used for securing deck hardware, mounting brackets, engine components, and other critical fastening applications on boats and marine equipment. The 316 stainless steel alloy provides superior corrosion resistance compared to 304 stainless steel, making it the preferred choice for below-waterline and saltwater-exposed installations. Sold in a convenient 10-piece bag.
