Lewmar Pro Series Fastening Kit (Metric)

Essential Mounting Solution for Reliable Anchoring Performance

Upgrading or repairing your boat's anchoring system starts with the right hardware. The Lewmar Pro Series fastening kit in metric sizing delivers precisely engineered components designed to secure Pro Series windlasses firmly in place. Whether you're replacing worn fasteners during routine maintenance or assembling a new installation, this kit ensures a rock-solid hold against the relentless motion of waves and wind.

Crafted from high-grade stainless steel, these fasteners resist corrosion from saltwater exposure, a common culprit in marine environments. Boaters often overlook the importance of quality mounting until vibrations loosen connections, leading to unreliable operation. This kit addresses that head-on, providing all necessary pieces for a professional-grade setup that withstands heavy loads and repeated use.

Seamless Compatibility Tailored for Pro Series Windlasses

Engineered specifically for Lewmar's Pro Series windlasses, this metric kit matches the exact specifications required for models across the lineup. No guesswork or mismatched parts—everything fits perfectly, from deck mounts to base plates. Metric threading is ideal for vessels built or serviced in regions favoring SI standards, ensuring smoother integration without adapters or custom drilling.

• Complete set includes bolts, nuts, washers, and screws optimized for windlass gypsy and motor housing.
• Prevents slippage during retrieval of heavy chain and rode under load.
• Supports both horizontal and vertical windlass orientations common in modern yachts.

Pro tip: Inspect your existing setup for elongated bolt holes or thread wear before installation. Pairing this kit with anti-seize compound extends fastener life in harsh conditions.

Step-by-Step Installation for Confident DIY Boaters

Installing this fastening kit transforms a potentially daunting task into a straightforward project. Begin by powering down the windlass and removing the old hardware. Clean the deck surface thoroughly to remove marine growth or residue, then apply marine sealant around bolt holes for a watertight seal.

1. Position the windlass base and mark drilling points accurately using a template if available.
2. Drill pilot holes slightly undersized for metric bolts to ensure a tight grip.
3. Torque fasteners to manufacturer specs—typically 20-30 Nm for most Pro Series mounts—to avoid over-tightening that could crack gelcoat.
4. Test operation with light loads before full deployment.

Common pitfalls include ignoring deck backing plates, which distribute load and prevent pull-through. For fiberglass hulls, reinforce with plywood or aluminum plates beneath for added strength.

Built to Endure Marine Demands

Durability defines this kit's value. AISI 316 stainless steel construction offers superior resistance to pitting and crevice corrosion compared to lesser alloys. In real-world testing by offshore sailors, these fasteners maintain integrity after thousands of anchoring cycles in tropical waters.

Beyond strength, the kit's precision machining minimizes play, reducing noise and wear on the windlass gearbox. It's a small investment that safeguards your larger anchoring system, potentially averting costly breakdowns mid-voyage.

Pro Maintenance Practices to Maximize Longevity

Keep your setup performing like new with simple habits. Annually inspect for galvanic corrosion, especially if dissimilar metals are nearby—use dielectric grease on threads as prevention. After extended layups, re-torque fasteners as wood or deck materials can shift with humidity.

For racing or charter boats under constant use, consider UV-resistant covers over exposed bolts to combat sun degradation. Integrating this kit into your seasonal service routine ensures peace of mind when dropping anchor in remote bays.
