* Left-hand thread screws: availability and price on request
* Commercial lengths every 0,5m +/- 5mm
Trapezoidal screws with a single thread according to DIN 103 (unified with ISO) are made by rolling a drawn bar made of low-carbon structural steel of the Ck15 grade (PN-93/H-840 191). The rolling method is a very effective treatment that does not damage the thread structure (so-called fiberization), the thread is smooth, without jams, which makes the cooperation between the nut and the screw more perfect (reduced friction resistance), and the life of the screw connection increases. Attention should also be paid to the better anti-corrosion properties of the rolled thread. The maximum length of trapezoidal screws is 3m (other lengths on request). The screw thread is made in 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
