* Left-hand thread screws: availability and price on request

* Commercial lengths every 0,5m +/- 5mm

Trapezoidal screws with single thread according to DIN 103 (unified with ISO), are made by rolling a drawn bar made of low-carbon structural steel, grade Ck15 (PN-93 / H-840 191). The rolling method is a very effective treatment that does not damage the thread structure (so-called graining), the thread is smooth, without jamming, thanks to which the nut-bolt cooperation is better (reduced frictional resistance), and the life of the screw connection is also increased. One should also pay attention to the better anti-corrosion properties of the rolled thread. Maximum length performed trapezoidal screws is 3m (other lengths on request). The thread of the bolt is made with the tolerance e7 and the nut H7

  • available diameters: from 10mm to 70mm
  • standard thread pitch: from 2mm to 10mm
  • accuracy of execution: +/- 0,15mm / 300mm (depending on the diameter of the screw)
  • straightness (bend radius): 0,1mm-0,5mm / 300mm (depending on the diameter of the screw)

Commercial sections of the screws: 0,5 m, 1 m, 1,5 m, 2,0 m, 2,5 m, 3,0 m

Cutting tolerance: +/- 5mm

Left screws - can be cut to size
