Phobya Screw UNC 6-32 x 40 cross (4xpcs) black nickel

Cross-recessed screws for mounting fans on radiators. The special UNC thread, from the non-metric unit system, has been specifically designed for radiators from the USA or the United Kingdom. They form an intermediate size between M3 and M4 threads. With a flat, slightly larger head, the screw sits well and can also cover larger holes that may be present with various types of covers. Therefore, they not only serve a structural function but are also visually appealing and look nice after installation. The thread length has been kept deliberately short to prevent damage to the fins from over-tightening during the installation of the fan, cover, or housing with the radiator. However, we would like to emphasize checking the length of the screw before installation! Important: These screws should only be used in combination with a 25 mm fan, as they are too long for narrower fans and can damage the radiator. If a fan cover is used with narrower fans (20 mm), they will fit again. Compatibility: XSPC, Swiftech, and others. Technical details: Material: brass, black nickel plated; Shaft length: 40 mm; Thread length: 8 mm; Head height: 3 mm; Wrench size: 6 mm. Delivery includes: 4x Phobya screw UNC 6-32 x 40 cross - black nickel. Caution: Over-tightening can damage the radiator; ensure the correct length of the screws. These screws may not be suitable in every case.
