PC Case Fan Long Screws #6-32 — 30mm Nickel-Plated Carbon Steel Phillips Screws for 25mm Case Fans, Black or Silver
Standard fan screws are too short for thick radiators, aftermarket fan brackets, or any mounting point where the thread engagement depth is greater than a typical case panel. PC builders, water-cooling enthusiasts, and anyone replacing stripped or missing fan screws knows the frustration of hunting for the right length in the right thread size. These PC case fan long screws use the industry-standard #6-32 UNC thread at 30mm (≈1.18") total length, sized specifically for 25mm thick case fans, so they seat fully without bottoming out or leaving the fan loose.
Each order ships the quantity and color you select above: 50-piece or 100-piece, in black or silver. Every screw is 30mm (≈1.18") long with a 3.5mm diameter shank and a Phillips round head. Material is carbon steel with a nickel-plated surface finish; the black variant adds a black coating over the nickel for builds where dark hardware is preferred. Thread standard: #6-32 UNC, compatible with virtually all ATX, Micro-ATX, and Mini-ITX case fan mounting points.
Typical use cases include PC case fan installation and replacement on 80mm, 92mm, 120mm, and 140mm fans where the standard short screws have stripped or gone missing; radiator fan mounting in single-fan configurations on 25mm thick fans attached to 120mm or 240mm radiators; and PC build upgrades where matching black or silver hardware is needed for a consistent aesthetic inside a windowed case.
🖥️ Compatibility: Standard #6-32 UNC fan mounting holes on ATX, Micro-ATX, and Mini-ITX PC cases. Fits 25mm thick case fans including 80mm, 92mm, 120mm, and 140mm sizes. Compatible with most PC case fan brackets and radiator fan mounts.
⚠️ Note: These 30mm screws are designed for single 25mm thick fan mounting. For push-pull dual-fan radiator configurations, longer screws are generally required. Verify your mounting depth before ordering.
✅ Key Features of These PC Case Fan Long Screws
-
🔩#6-32 UNC Thread — Industry Standard — The #6-32 UNC thread is the universal standard for PC case fan mounting used by virtually every ATX, Micro-ATX, and Mini-ITX case manufacturer. These screws thread directly into standard fan mounting holes without adapters or modifications.
-
📐30mm Length for 25mm Fans — At 30mm (≈1.18"), these screws are long enough to pass through a standard 25mm thick case fan and engage the mounting threads fully, without bottoming out or leaving the fan with insufficient clamping force. Fits approximately 99% of standard 25mm PC case fans.
-
🔘Phillips Round Head — Easy to Drive — The round pan head sits flush against the fan frame without digging in, distributing clamping force evenly across the mounting point. The Phillips drive works with any standard #2 Phillips screwdriver, including magnetic-tip drivers that prevent dropping screws inside the case.
-
⚙️Nickel-Plated Carbon Steel — Carbon steel provides the thread strength needed to hold fans securely under vibration. The nickel-plated finish resists light surface oxidation in indoor PC environments and gives the screw a clean, polished appearance that suits both windowed and closed cases.
-
🎨Black or Silver — Match Your Build Aesthetic — The silver version uses the standard nickel-plated finish. The black version adds a dark coating for builds where all-black hardware is part of the design. Both colors use identical dimensions and thread specifications.
-
📦50 or 100 Piece Pack — Choose Your Quantity — The 50-piece pack covers a full build with spares. The 100-piece pack suits builders who work on multiple systems, manage a workshop, or want a long-term supply of replacement fan screws on hand. Each order ships the quantity and color you select.

❓ Frequently Asked Questions
What fan thickness do these screws fit?
These 30mm screws are designed for 25mm thick case fans, which is the standard thickness for 80mm, 92mm, 120mm, and 140mm PC case fans. The 30mm total length provides enough thread engagement through the fan body and into the case mounting point without bottoming out.
What thread size are these screws?
These screws use the #6-32 UNC thread standard, which is the industry-standard thread for PC case fan mounting in ATX, Micro-ATX, and Mini-ITX cases. They are compatible with the fan mounting holes on virtually all standard PC cases and fan brackets.
Can I use these screws for push-pull radiator fan configurations?
The 30mm length is specifically suited for single-fan mounting on 25mm thick fans. For push-pull configurations where two fans sandwich a radiator, you would typically need longer screws (generally 55mm or more, depending on radiator thickness). These 30mm screws are intended for standard single-fan-to-case or single-fan-to-radiator mounting.
What is the difference between the black and silver versions?
Both versions are made from the same carbon steel with a nickel-plated finish. The black version has an additional black coating over the nickel plating for a darker appearance that blends with black PC builds. The silver version retains the standard nickel-plated finish. Thread size, length, and diameter are identical between both colors.
Are these screws corrosion resistant? Can I use them in a water-cooled build?
The nickel-plated finish provides moderate corrosion resistance suitable for indoor PC use, including water-cooled builds where the screws are not directly exposed to coolant. They are not rated for outdoor or high-humidity environments. For builds with significant moisture exposure, stainless steel screws would generally be a more appropriate choice.
How many screws come in each order?
You can choose between a 50-piece pack or a 100-piece pack, in either black or silver. Each order ships the quantity and color you select above.
What screwdriver do I need to install these screws?
These screws have a Phillips cross-head drive. A standard Phillips #2 screwdriver is typically the correct size for #6-32 fan screws. A magnetic-tip screwdriver is recommended to avoid dropping screws inside the case during installation.
