HOW TO DETERMINE YOUR THREAD SIZE
We stock products in two different thread sizes: 3/8 BSW or 5/16 BSW. These are the two standards that are used in Australia. If you are unsure of which size you need, there are a number of ways to confirm this:
- If you have an existing leg/castor/glide, and you want to buy the same product, you can purchase a nut that is either 3/8 or 5/16 BSW and try to screw it on to the thread of your existing leg/castor/glide (the thread size corresponds to the nut that fits onto it). Alternatively, you could take the existing leg/castor/glide to your local hardware store. The staff there should be able to confirm the thread size for you.
- If you do not have an existing leg/castor/glide, you can purchase a bolt that is either 3/8 or 5/16 BSW and try to screw it into the existing hole on your bed base (that the leg/castor/glide normally screws into).
These are best ways to accurately determine the thread size you require. Alternatively, you could call the manufacturer of your bed base or the retail store where you purchased your bed base and ask them to confirm the thread size of the leg/castor/glide used.
There is also a quick “cheat” to help determine the thread size, but it is not 100% accurate. You can take a standard pencil or BIC brand pen and try to insert it into the existing hole on your bed base (that the leg/castor/glide normally screws into). Generally, if the pen/pencil fits into the hole, you have a 3/8 BSW thread. If it does not fit, you have a 5/16 BSW thread. Please note, while this “cheat” works the majority of the time, it does not account for the pitch of the thread, and therefore is not a fool-proof way of determining thread size. Furthermore, imported products may use metric thread sizes which would also render this method inaccurate. Please note, we do not offer refunds for incorrectly ordered products and therefore highly recommend that you use one of the first two options listed above.
