## Long description

The Delock M5 x 40 mm Fan Screws Set 20 Pieces 42549 is an essential computer component accessory designed to provide secure and reliable mounting for cooling fans within custom PC builds and standard computer cases. This hardware kit ensures that fans remain firmly attached to radiators or chassis structures, minimizing vibrations and maintaining optimal airflow throughout the system. With precise thread dimensions and a standardized design, this screw set facilitates straightforward installation and maintenance procedures for desktop computers and liquid cooling setups.
Advantages
This hardware set offers precise M5 x 40 mm sizing, ensuring a snug and dependable fit for compatible computer fans and cooling radiators. The inclusion of 20 pieces in a single package provides sufficient quantity for installing multiple fans or maintaining a complete cooling array. Built from durable materials, these screws withstand the repetitive assembly and disassembly processes often required during hardware upgrades and system maintenance.
Suitable for
Mounting computer case fans to chassis walls
Securing cooling fans to liquid cooling radiators
Custom PC builds requiring M5 x 40 mm fasteners
Cooling system maintenance and hardware replacement
When it may not be suitable
This product may not be suitable if your computer case or cooling fan requires smaller or larger thread diameters, such as M3 or standard self-tapping fan screws. Additionally, the 40 mm length might be excessively long for standard direct-to-chassis fan installations that do not involve thick radiators or specialized mounting brackets.
Key specifications
Thread size: M5
Length: 40 mm
Quantity: 20 pieces
Application: Computer cooling fans and radiators
How to use
Align the mounting holes of the computer fan with the corresponding screw holes on the chassis or radiator. Insert the M5 x 40 mm screws through the fan frame and any intervening brackets or radiator surfaces. Tighten the screws manually using an appropriate screwdriver until the fan is held securely in place, taking care not to overtighten and damage the fan housing or cooling equipment threads.
What to consider before purchase
Verify the required screw diameter and length for your specific fan and radiator combination
Check the depth of the mounting holes to ensure the 40 mm length is appropriate
Ensure your hardware setup requires machine screws rather than self-tapping alternatives
Usage recommendations: Store unused screws in a dry container to prevent loss and corrosion. Periodically check installed screws during routine system maintenance to ensure they remain properly tightened and free from vibration-induced looseness.
