Corrosion-resistant fasteners, in the exact spec you need
316/A4 stainless steel and silicon bronze — in the quantity you need, even one piece. Every order is quoted and confirmed before you pay anything.
Most fastener sellers want you to buy a box. This store is built for the buyer who needs 12 pieces, or one piece, in a specific grade and size — and who would rather wait for a confirmed quote than gamble on a substitute.
Choose your alloy
316 / A4 Stainless Steel
The saltwater stainless. Molybdenum in the alloy gives 316 substantially better resistance to pitting and crevice corrosion in saltwater than 304 or 18-8 stainless. Hex bolts, machine screws, nuts, washers, threaded rod — in inch and metric sizes.
Silicon Bronze
The traditional boat fastener. Strong, non-magnetic, and highly resistant to saltwater corrosion — the standard choice for wooden boats, docks, and coastal work. Wood screws, machine screws, hex bolts, nuts, and washers.
Metric 316 — the hard-to-find sub-line
Metric 316/A4 sizes are often underserved in the U.S. market. If your project takes metric threads, say so in your quote request — diameter, pitch, and length — and we will confirm that exact size rather than offering an inch substitute. See the metric section on the 316 stainless page.
How ordering works
- Send a quote request with the exact specification: material, fastener type, diameter, thread, length, and quantity.
- We confirm in writing — availability, ship date, and price — against current supplier availability.
- You approve and pay only after confirmation. If we cannot confirm it, you pay nothing.
- We order and ship. If anything slips after you pay, you hear about it promptly, with the choice to wait or cancel for a full refund.

- Fabricators and maintenance buyers who need an exact grade and size, not a bulk box of almost-right.
What this store is not
We are a small seller, not a warehouse. We do not stock inventory, do not promise same-day shipping, do not claim certifications we do not hold, and do not substitute a different spec without your explicit agreement. If your job needs certified material, lot traceability, or delivery today, we will tell you plainly that we are not the right seller for it.
