A family-owned California fastener and industrial supply company — anchor bolts, structural and industrial fasteners, CNC machined parts, and the everyday hardware your projects run on.

California Fastener (founded 2020) carries on a Bay Area fastener business that’s been serving the trade since 1964. We bought the inventory, the customer relationships, and six decades of tribal knowledge — and have spent the years since adding our own.
We built the business on repeat customers, not one-off transactions — in-stock, dependable hardware from the leading manufacturers, backed by in-house CNC machining for the parts a catalog won’t cover.
Need it fast? Orders placed before 3 PM PST ship the same day. Need it after 3? Call us — we’ve gotten more than a few crews out of a same-day jam. Whether it’s one specialty bolt or a full bill of materials, you’re working with people who know the inventory and stand behind it.

The basics are simple, and we hold ourselves to them on every line item — whether it’s one Hollo-Bolt or a thousand-piece anchor assembly run.
Real inventory of the grades and sizes critical projects actually use — not a virtual catalog of someone else’s stock.
Mill test reports, heat numbers, and lot traceability included by default. Domestic-only certs available on request.
The CNC shop is in our building. The person quoting your job is the one routing it through the floor.
We don’t pad our dates and we don’t promise what we can’t ship. If a job is tight, we’ll tell you up front.
A snapshot of what’s in the building, what we ship, and what we hold to. We’ll keep this honest as we grow.
Across every industry we serve, hardware ships to a recognized standard with the documentation to match. A working list of the specifications and provenance requirements we routinely supply and certify to.
A working summary — for the long form, see the products and CNC pages. If you need something that isn’t here, ask. Most “custom” jobs are routine for us.
We’re a real address with real hours. Walk-ins welcome — call ahead if you’re driving more than an hour and we’ll have someone meet you.
Manufacturing, distribution, and CNC machining under one roof. Twenty minutes from the Bay Bridge, one block off I-680.
Every quote gets a real person. Drawings, specs, even a back-of-napkin sketch — we’ll work with what you have.
