What is 316 Garde Stainless Steel Boat Cleat?
A boat cleat is a fitting on a boat or ship used to secure ropes or lines for various purposes, such as tying off to a dock, securing fenders, or anchoring. Cleats are typically made of metal or strong plastic and are shaped like a pair of horns or a T-shape, providing multiple points for securing lines.
Boat cleats are mounted on the deck or gunwale of the boat and are designed to withstand the forces generated by wind, waves, and currents. They come in various sizes and designs depending on the size and type of boat they are intended for.
To use a boat cleat, a rope is typically wrapped around one of the horns of the cleat in a figure-eight pattern to create a secure and easily adjustable knot. This allows the boat to be quickly and securely tied up when docking or anchoring.
Cleats are essential for safely mooring a boat and are a fundamental part of a boat's deck hardware. They provide a reliable way to secure the boat in place and prevent it from drifting or moving unexpectedly.

Process Advantage: From Wax to Show‑Quality Hardware
A boat fitting lives in the harshest environment – salt spray, intense sun, and constant handling. It must look good and perform flawlessly for years. Here's how we deliver that:
① Precision Investment Casting
Complex geometry (undercuts, curved profiles) achieved via wax injection & ceramic shell.
316 stainless steel poured under controlled atmosphere – no inclusions, consistent chemistry.
② 4‑Axis CNC Machining of Functional Areas
Custom fixtures reference cast datums for repeatable accuracy.
Machined features:
Mounting holes & counterbores – positional tolerance ±0.05 mm
Sliding jaw surfaces – smooth adjustment without play
Any required threaded holes – Class 2 fit
③ Multi‑Stage Mirror Polishing
Step 1: Coarse belt grinding to remove gate stubs & scale.
Step 2: Progressive abrasive finishing (80 → 400 grit).
Step 3: Final buffing with compound → high‑gloss, defect‑free surface.
Every part inspected under LED lighting against a master gloss sample.
Quality Assurance – Beauty That Lasts
| Checkpoint | Standard |
|---|---|
| Salt Spray Resistance | Random samples pass ASTM B117 (48 hr) – no pitting. |
| Dimensional Accuracy | CMM inspection reports available for critical features. |
| Surface Finish Verification | Compared to physical master sample under controlled light. |
| Material Identity | PMI (Positive Material Identification) per heat. EN 10204 3.1 certificates supplied. |

Why This Jaw Slide Is Different
Many marine fittings are cast and sold as‑is, leaving rough surfaces and sharp edges that trap salt and detract from your boat's appearance. We go further:
CNC machining the functional surfaces ensures your canopy adjusts smoothly without binding.
Mirror polishing every visible face means the hardware complements your boat's finish rather than detracting from it.
Send us your drawing or sample. We'll provide first‑article castings with machined features and a polished finish for your approval before production.
