The RICHWITS Marine Grade Stainless Steel Diamond Pad Eye is a heavy-duty, precision-cast hardware fitting engineered for high-load attachment points on boats, yachts, and outdoor structures.
Manufactured from AISI 316 stainless steel, it survives lifelong exposure to salt spray, UV, and extreme temperatures without pitting, rusting, or losing mirror polish.
| Feature | Benefit |
|---|---|
| 316 marine-grade stainless steel | Ultimate resistance to chlorides & saltwater |
| Investment-cast diamond base | Zero porosity, higher breaking load than stamped plates |


Q1: Can I use the 5 mm version for a 250 kg swing?
A: No. Select the 8 mm (WLL 500 kg) or larger to maintain a 5:1 safety factor.
Q2: Will the mirror polish scratch when sand hits it?
A: Electro-polished surface is 30 % harder than raw 316; minor scuffs can be restored with a Scotch-Brite pad.
Q3: Do you supply matching backing plates?
A: Yes, laser-cut 316 plates with identical hole pattern, 3 mm or 5 mm thick, sold separately.
Q4: Is the ring welded all around?
A: Absolutely—full 360° circumferential TIG weld, dye-pen tested 100 %.
