Halder Precision Slot Nuts

Halder Precision Slot Nuts | High-Accuracy Workholding Fasteners | Freer Tool

Halder precision slot nuts are workholding fasteners used to create a repeatable, threaded mounting point inside a machine table slot for clamps, fixtures, and tooling (application dependent). Compared to general-purpose slot nuts, precision styles are typically chosen when fit, alignment, and consistent positioning matter—helping fixtures seat more predictably and reducing play in the slot (application dependent). They’re commonly used on milling machine tables, fixture plates, and modular clamping setups where accuracy and repeatability are priorities.

Ground Slot Nuts with Narrow Tolerances for Very Precise Clamping - Precision slot nuts are ground slot nuts. Due to the narrow tolerances, they are ideal for very precise clamping. A precision slot nut is used for a fast and precise adjustment of fixtures and workholding systems on machine tables (with T-slots). The wide product range includes various versions from stock. Customized designs can also be designed and manufactured for special applications.
