Double End Threaded Bar (DIN 938)

Double End Threaded Bar (also known as Dual Threaded Rod or Double End Studs) are made to DIN 938 standard and available with equal threads (the same amount of thread at each end) and unequal threads (one end has more thread than the other).

Dual Threaded Rod (or Dual Ended Rod) is suitable for a wide range of applications, typically when the rod is fitted into an unthreaded hole, where the double thread enables fixing with nuts on either side, for example in doors and assembly housings.

Double End Studs are available from Fastenright in A2 and A4 Stainless Steel, with thread sizing from M6 to M24.

b1 measurements range from 6mm to 24mm (smaller end) and b2 measurements from 18mm to 54mm (larger threaded end).

Non-standard lengths and sizes are available to order, with short lead times.
