Trapezoidal thread design. Use with metric leadscrew thread listed in separate category.

Material: KSM = Carbon Manganese Steel S300 Pb (11 SMn Pb37) / LRM = Bronze CuSn8P. Carbon Manganese steel can be welded but difficulties may arise with bubbling due to sulphur content. KSM: Manual control control only - low rotational speeds only - for clamping or locking functions - for receiving dead weights. LRM: Manual or powered control - low and medium rotational speeds - for working under load. For power transmission and continuous use always use bronze nuts not steel.
