Knurled screw GN 653.2-M4-17-ST Z067545

Slotted screws GN 653.2 are a practical solution wherever disassembly of components is required without completely unscrewing the screw. The design of these screws, with a thread located only on the end of the shank and a reduced diameter over the remaining length, prevents loss during initial unscrewing.

Design features and application

GN 653.2 screws are used in situations where frequent disassembly is necessary – e.g., for machine covers, access panels or adjustment elements. Mounting is done through a threaded hole in the joined elements (d1), and depending on the design, may require an additional transition hole (d5) in one or both elements. This solution will be appreciated by both installers and end-users who value convenience and quick access to components.

Material and durability

Made of steel, GN 653.2 screws provide good strength and resistance to mechanical damage. The ST version (steel) is suitable for most industrial and workshop applications. This ensures reliable operation for a long time.

It is worth noting the key features of the product: the thread diameter is M4, and the shank length is 17 mm. The knurling diameter is 3.2 mm with a height of 5.5 mm. In addition, the screw has smooth sections of the shank with lengths of 2 mm and 5 mm, which affects its functionality and ease of assembly. These parameters allow for precise selection of the screw for a specific application and ensure stable fastening of the elements.
