Trapezoidal threaded nuts - Import export

Steel C35Pb. Gunmetal Rg7. Plastic PA6.6 with MoS2). ISO trapezoidal thread based on DIN 103. Steel nuts for adjustments during manual operation and as fastening nuts. Not advised for use with motorised drives due to the steelsteel material combination. Gunmetal nuts for motion drives with low and medium speed. By insufficient lubrication, gunmetal trapezoidal thread nuts on steel spindles have good dryrunning properties. Plastic nuts for lownoise motion drives. Good dryrunning properties. Tolerance class 7H.

Steel 1.0401 (C15) or stainless steel 1.4301 (whirled spindles stainless steel 1.4305). Version Steel rolled, bright. Stainless steel up to Tr 40x7 rolled, above this whirled, bright. Note Rolled, high precision trapezoidal thread spindles. ISO trapezoidal thread based on DIN 103. The trapezoidal thread spindle is a transmission thread with relatively high friction. Standard thread forms are selflocking. This has the advantage that they generally do not need to be secured in the rest position. Tolerance class 7e Pitch precision 0.3/300 mm Length sawed with excess, ends not deburred.

When screwing the nuts onto the thread, the thread lock is plastically and elastically deformed. The elastic deformation causes a radial frictional lock against the nuts being loosened. The plastic thread lock is only effective when the nuts are fully screwed onto the male thread. The screw length must be selected so that at least two full threads protrude from the nut. Due to the plastic deformation of the thread lock, these nuts should only be used once.
