Low Profile Socket Barrel Nuts

SKU: SB004 Category:

Low Profile Socket Barrel Nuts In Stock

Socket Barrel Nuts with a low profile head are ideal for use in architectural applications that require two or more pieces of material to be clamped together whilst also leaving an aesthetic finish. This is particularly useful for applications where a flat countersunk head is required but the material is too thin to countersink.

These barrel nuts can be referred to as sleeve nuts.

  • Smooth, thin head – no need to countersink holes to achieve a low profile finish
  • Ideal for architectural applications
  • Male screw fastens into internally threaded female barrel nut (sex bolt)
  • Standard socket drive
  • Closed end
  • A4 stainless steel as standard for superior corrosion resistance

Low Profile barrel nuts are available as standard in A4 stainless steel which makes them ideal for applications that require protection from salt water corrosion, however they can be used in any application that requires stainless steel. They are available as standard from M5 to M8 thread, with other threads available to order. These sleeve nuts are suitable for use with any machine screw with the same thread.

Please contact us with your requirements to further your enquiry.
