Flanged Rivet Nut

Flanged rivet nuts are manufactured in three primary material families including carbon steel, stainless steel, and aluminum. Carbon steel typically uses grades 1008 or 1010 with yellow zinc chromate coating according to standard industrial plating methods. Stainless steel comes in two austenitic grades including A2 for general environments and A4 for superior resistance against marine and chemical corrosion. Aluminum grades 5056 or 6061 are used for lightweight applications in aerospace and transportation industries. The main production standards for these components include ISO 15983 and DIN 7337 for large flange types. Aerospace specifications NAS1329 and NAS1330 are also defined for applications requiring tight tolerances and high quality control.

Nominal sizes of these nuts range from M3 to M12 in the metric system and from 4-40 to 1/2 inch in the imperial system. Flange diameter for size M4 equals 9 millimeters while size M8 reaches approximately 16 millimeters. Flange thickness varies between 1.0 to 2.0 millimeters depending on size to ensure proper clamping force distribution. Tensile strength for a carbon steel M8 sample reaches approximately 5700 Newtons with shear strength around 4900 Newtons. Grip range for each nut depends on its body length; for example an M6 nut

rail nut

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 sh

Lock nut

Prevailing torque lock nuts are made from Grade 5 or 8 carbon steel with hot-dip galvanized or dichromate coating. Their common inner diameter ranges from M3 to M24 per ISO 7040 standard. The total nut height is typically 0.8 to 1.5 times the nominal diameter. The locking element features an integrated washer or a nylon-6,6 ring with 30% glass fiber. The operational temperature range for this polymer ring is -40 to +120°C. The minimum breakaway torque after locking is 0.5 to 1.5 times the nominal tightening torque. The steel body hardness reaches 70 to 100 Rockwell B after heat treatment. Coating thickness on the body is between 8 and 12 microns. This coating ensures corrosion resistance for up to 500 hours in salt spray tests.

The nut structure consists of a hexagonal base and an integral locking section. The internal nylon ring typically covers 180 to 360 degrees of the thread circumference. The effective diameter of the polymer ring is about 1.1 times the base thread diameter. This design creates a radial pressure of 50 to 100 MPa on the screw. The recommended tightening torque with a torque wrench is between 5 and 400 Nm. Grade 8 nuts maintain their locking capability under vibrations of 10 to 2000 Hz. The tensile strength of these nuts ranges from 520 to 830 MPa. The int
