This AAP galvanised hexagon backnut is a mild steel fitting with BSP threads. It is supplied in 9 sizes, 1/8 in (6 mm) to 2 in (50 mm).
A hexagon backnut is a flat hexagon nut threaded inside. It is tightened against a fitting, panel or bracket to lock a threaded pipe or fitting in place. B is the hexagon across flats and C the thickness, as lettered on the AAP drawing.
AAP states that its steel threaded pipe fittings are made to BS EN 10241:2000 (manufacturer-stated). It is galvanised. AAP does not state the galvanising process or coating thickness for this item. AAP states that all sizes of its fittings other than unions are sample tested to 5.2 MPa (manufacturer-stated). These are test pressures, not working pressures, so confirm the pressure and temperature for your application with AIMS before you order.

Selecting the right option
Choose the size to match your pipework. These fittings are BSP threaded, so check that your pipe or fitting is BSP and not NPT before you order. AAP also lists a size (SBN80G) in this range, which AIMS does not currently list. Ask if you need one.
