M4 x 10 mm countersink screws

These black-oxide alloy steel fasteners use a hexagonal drive for straightforward installation with a 2.5 mm key. The countersunk head sits flush once driven, making them suited to PC water-cooling builds and general hardware assembly where a low-profile finish is required.

7 mm thread engagement limit

Only 7 mm of the 10 mm length is threaded, so the screw cannot clamp thicker panels or bite deeper than that allowance. Over-length fasteners risk contacting radiator fins or internal components, so the short thread length defines the maximum material stack the screw can safely secure.

Single-length pack constraint

The kit supplies one fixed 10 mm length, so it covers only joints that match this exact reach. Builds needing longer engagement, different diameters or a variety of lengths will require separate fastener packs.

Questions about this item

How do I pick the right screw length for my radiator?

The 10 mm total length with 7 mm thread should sit flush in standard M4 countersunk holes; screws that are too long may damage the radiator.

What does the 2.5 mm drive size mean when I am assembling the loop?

A 2.5 mm hex key fits the head, giving positive torque transfer and reducing the chance of stripping during installation.

What standard governs the thread and dimensions of these M4 screws?

They are manufactured to DIN guidelines, so the M4 pitch and countersink profile match industry-standard metric fasteners.
