DIN 508 T-slot Nut
FLOK supplies DIN 508 T-slot nuts: M5–M48, steel 40/40Kh/45, property class 8 and 10, as well as versions in 12×18N10E and aluminium.
DIN 508 standard covers nuts used for T-slots, also known as T-nuts. Such nuts have a rectangular shape with a T-shaped cross-section, with a through hole with internal metric thread located in the center.
Guide chamfers are removed from the bearing side of the head — this simplifies installation of the fastener into the slot. Nuts of this type are in demand in mechanical engineering: they are used in machine tool building, assembly of various instruments, equipment, and vehicles.
Technical specifications
The fastener is designed for repeated assembly and disassembly of the joint, so it is made of high-strength carbon steel grades 40, 40Kh, 45. The property class of the metal is 8 or 10, and no protective zinc coating is provided. The standard also provides for manufacturing T-slot nuts from steel grade 12×18N10E or from aluminium — fasteners made of non-ferrous metals can be used in highly corrosive environments.
The product has the following characteristics:
- Hole thread diameter – from M5 to M48. The wide range simplifies the selection of a fastener for a specific task.
- The overall height of the product can range from 8 to 70 mm.
- Nut head height – from 4 to 34 mm.
- Equivalents are manufactured to the international standard ISO 299, which may have a number of differences.
The nut is used together with bolts, studs, and other types of fasteners of the corresponding diameter to securely fix the components of various assemblies.
Application
The main application area of T-slot nuts is heavy machinery. They are used as a fastening element of various fixtures for securing parts on machine tools equipped with tables, as well as for assembling components and equipment on T-slot plates. The fastener is designed for long-term continuous use with repeated tightening and loosening.
