A1: DIN 508 specifies the dimensions and technical requirements for T-Slot Nuts. These are specialized square nuts designed to slide into the T-shaped channels (T-slots) commonly found on machine tool tables, milling machines, lathes, rotary tables, and modular framing systems. Their primary function is to provide a secure, adjustable, and removable threaded anchor point within the T-slot for attaching clamps, fixtures, workpieces, or other components.
A3: The key features revolve around their integration with standardized T-slots and their material-dependent properties for different environments.
| Feature / Material | Description & Purpose |
| Primary Function | To be inserted and slid along a T-slot channel, providing a movable threaded connection point for setup studs, bolts, and clamping elements. |
| Common Pairing | Typically used with setup studs, clamping kits, and shoulder bolts to create flexible and secure workholding solutions. |
| Standard Strength | Tempered to a high strength grade of 10.9 (according to European standards), ensuring they can withstand significant clamping forces without failure. |
| Slot Compatibility | Designed to fit standardized T-slot widths. Common sizes cover slot widths from 6mm to 18mm. |
| Material | Key Properties | Ideal Application Environment |
| Steel (Black-Oxide Finish) | Provides a dark, matte appearance. Offers minimal corrosion resistance. | Dry, indoor environments (e.g., standard machine shops) where appearance is a consideration and rust is not a concern. |
| Stainless Steel A2 (18-8) | Offers excellent corrosion resistance. Non-magnetic in annealed state. | Wet, humid, or washdown environments; applications requiring non-magnetic properties; EDM (Electrical Discharge Machining) applications; or when used with stainless steel components. |
Note on Installation:
Always ensure the T-slot nut is properly oriented (usually with the threaded hole facing upwards) and fully seated in the slot before applying torque to the fastener.
For maximum holding power and to prevent damage to the T-slot, use a nut that correctly matches the slot width and pair it with a bolt of appropriate grade and length.
