DOTTIE HNBZ516 5/16"-18 Hex Nuts
These DOTTIE HNBZ516 hex nuts have a 5/16"-18 thread and are made from silicon bronze. The pack contains 50 pieces for hardware assemblies. They suit automotive, marine and general fastening tasks where corrosion resistance matters. The silicon bronze material resists saltwater and chemical exposure.
Replacing standard steel hex nuts
Swap these in when steel nuts corrode or gall in wet or salty environments. The jump is worth it on boats, dock hardware or outdoor brackets that see repeated moisture. Silicon bronze prevents the rust streak and seizure common with plated steel. They also avoid the galvanic reaction that damages aluminium or stainless parts.
Build fit: 5/16"-18 thread compatibility
These nuts mate with any 5/16"-18 bolt or threaded rod in the build. The 50-count pack covers multiple joints without re-ordering. Silicon bronze frees up maintenance time because the nuts do not fuse to the bolt threads. No special tools are needed beyond a standard wrench or socket for the hex head.

Questions about this item
What thread size and pitch do these silicon bronze hex nuts use?
Each nut has a 5/16"-18 thread, meaning 18 threads per inch on a 5/16 inch diameter bolt.
How are these hex nuts installed, and what is the common mistake?
Thread the nut onto the matching 5/16"-18 bolt by hand, then tighten with a wrench; the common mistake is cross-threading by forcing it before the threads engage.
When will these silicon bronze hex nuts need replacement?
Silicon bronze resists corrosion well, so replacement is only needed if threads strip, the nut rounds off, or the joint is disassembled and the nut is damaged.
