Halder Knurled Nuts & Thumb Screws | DIN Standards | Flat & Collar Designs

Halder knurled nuts and knurled thumb screws are hand-operated fasteners designed for tool-free tightening and quick adjustments in fixtures, machine guards, jigs, and industrial assemblies (application dependent). The knurled (textured) grip makes it easier to tighten by hand, which is especially useful for frequent changeovers, setup adjustments, and access panels where using a wrench or driver slows things down. These components are commonly used anywhere you want repeatable hand-tightening with good grip and consistent feel (application dependent).

Knurled nuts and knurled thumb screws are operating elements that comply with DIN or company standards. They are also commonly known as adjusting screws or adjusting nuts. These components are versatile and can be used across various industries for numerous applications.
