DIN508 T-Slot Nuts
DIN 508 T-Slot Nuts provide a movable threaded fastening point inside the T-slots of machine tables and other compatible profiles. The nut can be positioned along the slot before tightening, allowing fixtures, tools, brackets, and other components to be mounted at the required location without drilling additional holes in the table or profile.
The T-shaped body is designed to engage with the slot and resist rotation when the mating bolt is tightened. This allows the fastening position to be changed during setup while keeping the nut captured within the slot. Compared with fixed threaded holes, the sliding arrangement gives greater flexibility when the position of a fixture or component needs to be adjusted. DIN 508 T-Slot Nuts are commonly used with machine-tool tables, workholding fixtures, clamping systems, machining equipment, and compatible T-slot profiles. Different thread sizes and materials can be selected to match the bolt, slot dimensions, clamping requirements, and working environment.
Specification:
DIN 508 T-Slot Nuts are specified by the thread size, T-slot dimensions, nut length, and material, with the body geometry matched to the corresponding machine-table or profile slot. The T-shaped body is designed to remain captured within the slot while providing a threaded point for the clamping bolt.
The standard range covers different metric thread sizes and slot configurations. Carbon steel and stainless steel versions are available, allowing the same T-slot fastening concept to be used across different equipment and operating environments. Carbon steel nuts can be supplied with finishes such as zinc plating or black oxide, while stainless steel versions can be supplied in plain or passivated condition.

Dimension Chart of DIN508 T-Slot Nuts :
The DIN 508 dimension chart provides the key measurements needed to match the T-slot nut with the corresponding machine-table or profile slot. In addition to the metric thread size, the chart covers the body dimensions that determine how the nut sits and moves inside the T-slot.
When selecting a DIN 508 T-Slot Nut, the thread size should match the clamping bolt, while the nut width and height should correspond to the available T-slot dimensions. The nut length and other body dimensions can also affect the available clamping area and installation clearance. Refer to the dimensional values below when checking compatibility with an existing machine table, fixture, or T-slot profile.

Application of DIN508 T-Slot Nuts:
DIN 508 T-Slot Nuts are used wherever components need to be clamped to a T-slot while retaining the ability to adjust their position before tightening. The nut slides or is positioned inside the slot and provides a threaded fastening point for the mating bolt, making it particularly useful for modular workholding and fixture systems.
Machine Tables and Workholding Fixtures
DIN 508 T-Slot Nuts are commonly used on machine-tool tables, workholding fixtures, clamping plates, and machining setups. They allow clamps, stops, brackets, and other tooling components to be positioned along the available T-slots and secured with matching bolts.
Clamping and Adjustable Mounting Systems
The sliding connection is useful for clamping devices, adjustable supports, mounting brackets, positioning fixtures, and modular tooling systems where the fastening location may need to change between different setups. Instead of relying on fixed threaded holes, the T-slot provides a continuous range of mounting positions.
Industrial Equipment and T-Slot Structures
DIN 508 T-Slot Nuts can also be incorporated into industrial machinery, assembly fixtures, inspection equipment, workbenches, machine frames, and compatible T-slot structures where removable or repositionable components need to be attached without drilling additional mounting holes.
