FAQs
Are these nuts compatible with metric bolts?
No, these are British Standard Whitworth (BSW) nuts and have a different thread pitch than standard metric hardware.
What does the 5/16" specification refer to?
It refers to the nominal diameter of the bolt that the nut is designed to fit.
Can these be used in outdoor environments?
Yes, the silver finish offers corrosion resistance, making them suitable for many outdoor applications, though consistent maintenance is recommended for coastal or high-salt areas.
What does 'Full Nut' mean?
A full nut is a standard-height hexagonal nut, as opposed to a 'lock' or 'half' nut, providing maximum thread surface contact for better holding power.
Are they reusable?
Yes, provided the threads remain clean and are not stripped during the initial removal process.
Troubleshooting
Nut does not thread onto the bolt
Verify that your bolt is 5/16" BSW and not a metric or UNC equivalent. Check for damaged or deformed threads on the bolt end.
Nut is difficult to turn mid-assembly
Back the nut off completely and check for grit or metal shavings inside the threads. Clear debris and re-thread carefully.

Setup, Compatibility & Care
To ensure the longevity of your assembly, always verify that your bolts feature a matching 5/16" BSW thread pitch. Do not attempt to force these onto metric or UNC bolts, as this will cross-thread the components. When installing, turn the nut by hand until finger-tight to ensure the threads are aligned, then finish with a calibrated torque tool or standard spanner. For maintenance, keep the threads free of debris; in outdoor or high-moisture environments, a light application of machine oil or anti-seize compound is recommended to further prevent oxidation.
