Knurled screw GN 653.2-M4-15-ST Z061436

Knurled screws – reliable fastening with the possibility of disassembly

Knurled screw GN 653.2 is a fastening element used wherever quick and convenient fastening with the possibility of disassembly without complete unscrewing is required. This is an ideal solution for covers, access panels and other elements that need to be regularly removed for servicing or maintenance. Made of ST steel, it provides good strength and corrosion resistance under typical operating conditions.

Construction and mounting

The key feature of this screw is the thread located only on the end part of the shank. The rest of the shank has a reduced diameter, which prevents the screw from being lost after it has been partially unscrewed – this is a very practical solution, especially in hard-to-reach places. Mounting is done through a threaded hole in the joined elements (d1). Depending on the design, it may be necessary to make an additional transition hole (d5) in one or both elements.

Applications and benefits

• Quick disassembly: Allows easy and quick removal of elements without completely unscrewing the screw.
• Preventing loss: The reduced shank diameter prevents the screw from being lost after it has been partially unscrewed.
• Versatility: Suitable for various applications, such as mounting covers, access panels and other elements requiring regular access.
• Durability: Made of ST steel provides good mechanical strength and corrosion resistance.

Screw GN 653.2 is a simple but effective solution for installers and end users looking for a reliable way to fasten elements with the possibility of quick disassembly. It is particularly useful in situations where access to the screw is limited or when frequent maintenance or repair of the device is necessary.
