Wooden Round Bun Foot | Sofa Legs - Stained and Natural

Information

Thread Size

These sofa bun feet are connected by threaded rods into matching metal fittings. If other methods of connecting legs have been used on your furniture, then new 10mm diameter drill holes may be required to use these legs.

The two metal thread size options available with these legs are Imperial 5/16" or Metric M8. Please note that although both are 8mm in diameter or very close to it, they will not connect, and it is difficult to visually tell them apart.

Therefore, to determine if you need to choose 5/16" or M8 threads (or something else) for your existing furniture, do the following:

• Take an existing leg to a local hardware store and check the thread on a nut in the Fasteners Dept.  Some stores have a sizing board with various-sized nuts for this purpose.  Try your bed leg on a metric M8 nut if there is no sizing board. 
  • If on a metric M8 nut it goes on after 4 or 5 turns it is metric M8.  If it jams after 4 or 5 turns it is Imperial 5/16". 
  • If the thread on your bed legs is too big for an M8 nut, try it on a metric M10 nut.  Once again, if it goes on after 4 or 5 turns, it is metric m10. If it jams after 4 or 5 turns, it is an Imperial 3/8" size. 

Based on that, you will have identified the correct size.

• Alternatively, you may send one leg to us for sizing.  We will identify the thread size immediately and advise you on what to order. We will return your leg with your order (freight will be charged).
• Or buy the option leg + Fitting and drill 10mm (d) x 22mm (d)  holes approximately 30mm from the existing fittings (to avoid splitting the timber) and screw in the fittings supplied.  They will exactly match the threaded rods on your new legs.  You will need either an 8mm Allen Key tool or an 8mm straight blade screwdriver to screw in the new Insert Screw metal fittings.  In this situation, it will not matter if you order 5/16" + Fitting or M8 + Fitting. Attaching these new fittings is considered a good DIY project and is not particularly difficult.  Once the fittings are screwed in then your new bun feet will simply screw into the middle of the fittings.
