Dexter Marine Products

<h3>About Dexter Marine Products</h3><p><strong>Dexter</strong> has been a cornerstone of the trailer components industry since 1960, earning a reputation as one of the most trusted names in axles, brakes, suspension, and related hardware. Headquartered in Elkhart, Indiana, Dexter employs more than 3,800 skilled professionals across the United States and Canada, operating facilities dedicated to engineering, manufacturing, and rigorously testing every product they produce.</p><p><a href="/12891-dexter-marine-products">Dexter Marine Products</a> occupies a unique position in the market: while the parent Dexter brand serves a broad spectrum of industries — utility trailers, RVs, heavy-duty commercial vehicles, agriculture, and manufactured housing — the DexMarine line is purpose-built for the demanding world of boat trailers and watercraft transport. <a href="/12891-dexter-marine-products">Dexter's marine-focused components</a> are engineered to withstand the corrosive effects of saltwater and freshwater submersion that would quickly degrade lesser parts.</p><h3>Why Dexter Stands Apart</h3><p><a href="/12891-dexter-marine-products">Dexter</a> is widely recognized as a world leader in developing and producing safe, reliable trailer components. Their in-house laboratory performs rigorous stress, fatigue, and metallurgical evaluations, while computer-equipped test vehicles analyze real-world product performance. This commitment to quality is reflected in every axle, actuator, brake, and hub that leaves a Dexter facility.</p><p>The product lineup covers an impressive range of needs. <strong>Torflex&reg; torsion axles</strong> offer independent wheel movement and progressive torque action for a smoother, quieter ride — a major benefit when transporting boats over rough roads or boat ramps. <strong>Sprung axles</strong> utilize double-eye and slipper spring configurations and can be mounted in underslung or overslung arrangements. For braking, Dexter's legendary <strong>Nev-R-Adjust&reg; brakes</strong> are a go-to choice for boaters who need reliable, maintenance-friendly stopping power.</p><p>The DexMarine hydraulic brake actuator lineup — including the DX8.0, DX12.5, and DX20EX models — handles capacities up to 20,000 lbs., giving boat trailer owners confidence whether they&apos;re launching a small fishing boat or a full-size yacht. Hub and drum assemblies, wheel bearings, seals, and suspension components round out the portfolio, ensuring that every critical point of contact between trailer and road can be equipped with a genuine Dexter part.</p><h3>Serving Every Trailering Application</h3><p>Beyond the marine world, Dexter&apos;s product ecosystem extends into cargo trailers, utility trailers, recreational vehicles, and heavy-duty commercial applications. With over 50 distribution branches and 350 distributor partners across North America, finding the right replacement component is straightforward for dealers and do-it-yourself enthusiasts alike. All products are manufactured in an ISO 9001:2015 certified environment and backed by Dexter&apos;s Genuine Limited Warranty, underscoring the brand&apos;s commitment to long-term reliability.</p><p>Whether you&apos;re building a new boat trailer from scratch, performing seasonal maintenance on an existing rig, or upgrading to a higher-capacity braking system, Dexter Marine Products provides the engineered solutions that professionals and passionate boaters rely on every season.</p>

Product Details

The Dexter Marine Products 81170 wheel lug bolts are essential replacement hardware for boat and utility trailers with threaded hubs. This 5-pack of zinc-plated lug bolts provides reliable wheel mounting for trailer wheel hubs, brake drums, or disc brake rotors.

Key Features:

  • 1/2"-20 thread size with tapered seat design
  • Zinc plated finish for corrosion resistance in marine environments
  • 7/8" thread length for secure engagement
  • Overall length: 1-5/8"
  • Constructed from steel with chrome plating
  • Convenient 5-pack quantity

These lug bolts are designed for trailers with bolt-on wheel systems where the bolts thread directly into the hub, drum, or rotor rather than using separate studs and nuts. The zinc plating provides protection against rust and corrosion, making them ideal for marine applications and harsh environments. Compatible with Dexter and Tie Down Engineering trailer hubs requiring 1/2"-20 threaded fasteners.
