Leadscrews
Trapezoidal thread design. Use with metric leadscrew thread listed in separate category.
Material: Carbon Manganese Steel S300 Pb (11 SMn Pb37). If welding, difficulties may arise with bubbling due to sulphur content. To be used with screws:- LFM, LSM, LRH, LSRH (Single Start). Manual control - Low rotation speeds - For clamping or locking functions - For receiving dead weights. For power transmission and continuous use, always use bronze nuts, never steel. Nuts and screws should always be lubricated with grease or oil.
