Knurled screw GN 653.2-M6-34-NI Z061505

Slotted screws GN 653.2 are a practical solution for applications where disassembly of a component 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 on the remaining length, prevents the loss of the component after it is loosened. This is particularly useful in situations where access to the screw is difficult or frequent disassembly is necessary during servicing.

Features and application

GN 653.2 screws are widely used in machines and equipment where quick and convenient fastening of cover elements, access panels or other components is required. Mounting is done through a threaded hole in the joined elements – d1. Depending on the design, an additional transition hole with a diameter of d5 may be required in one or both of the joined elements. Made of AISI 303 NI stainless steel, they provide corrosion resistance and durability in various environmental conditions.

Advantages and benefits

• Connection retention: The reduced shank diameter prevents the screw from being lost after loosening, increasing safety and facilitating servicing.
• Quick disassembly: The thread on the end of the shank allows for quick screwing and unscrewing without full removal.
• Corrosion resistance: Made of AISI 303 NI stainless steel guarantees durability and resistance to external factors.
• Versatility: Can be used in various constructions thanks to the flexible mounting system (threaded hole d1 and optional transition hole d5).
• Precision: Accurate dimensions (a1: 12-16 mm, a2: 16-22 mm, a3: 22-26 mm) allow for adaptation to specific applications.

It is worth noting the dimension l1, which is 34 mm – this is the length of the knurled part, which provides a comfortable grip when tightening and loosening the screw. The thread diameter M6 and the diameter d4 of 4.8 mm are crucial for proper fit into the appropriate threaded holes.
