rail nut , Iran

The rail nut features a rectangular body with two symmetrical side wings on both sides. These side wings exactly match the internal T-shaped groove of the rail for controlled sliding movement. The rail nut height ranges from 6 to 24 millimeters depending on the rail size. Wing width varies between 8 and 32 millimeters with each wing thickness of 2 to 5 millimeters. The central internal metric thread with sizes M4 to M20 is positioned perpendicular to the nut surface. Thread pitch is selected according to coarse or fine thread series based on application requirements. A 15 to 20 degree angle on the upper edges of wings provides better locking inside the rail groove. Dimensional tolerances for these nuts are manufactured in class h11 for length and width and class h13 for height.

Rail nuts are manufactured from medium carbon steel with property class 8.8 or 10.9 strength grades. Hardening and tempering heat treatment produces surface hardness of 28 to 32 Rockwell C. White or yellow galvanized coating with 8 to 12 microns thickness provides corrosion resistance. Stainless steel grades A2 and A4 are also produced for wet and marine corrosive environments. The spring rail nut features a spring steel sheet with 0.5 to 1 millimeter thickness positioned under the wings. This spring sheet prevents vibration-induced loosening of the nut during machine operation. Primary applications include assembly of CNC machine rails, production line rails, industrial molds, and aluminum profile workbenches.You can order and buy rail nut from Iran by contacting us through whatsaap and email.
