A stripped screw head, a fan that rattles against the case wall, or a fastener that corrodes after a single season — these are the complaints that separate a reliable set of pc fan screws from a cheap plastic bag of mismatched hardware. Fans are among the most vibration-prone components in a build, and the screws holding them must withstand constant thermal cycling without loosening or stripping.
What actually matters in this category comes down to thread compatibility, material grade, and quantity relative to your build size. A 120mm case might need four screws per fan and eight or more fans total, while a compact ITX build gets by with a fraction of that. We compared published specs, pricing, and recurring owner feedback across the options below to identify which sets deliver consistent threads, which include the right mix of lengths, and which simply waste your money on fasteners that will never fit a fan mount.

How We Picked
We evaluated each option on four criteria: thread standard compatibility (does the kit cover both #6-32 and M5 mounts?), material quality (stainless steel versus low-grade plated steel that rusts or strips), quantity-to-price ratio relative to typical build needs, and consistency of owner feedback regarding thread accuracy and packaging. Kits that included only one thread type scored lower because they limit versatility across motherboard, drive, and fan positions within the same case.
The 8 Best Pc Fan Screws in 2026
Easycargo PC Case Fan Screws (50 Pack Black)
This set suits builders who need a single affordable package covering fan sizes from 60mm through 140mm without thinking about thread length compatibility across multiple vendors. The black finish matches modern case interiors, and fifty pieces handle a mid-tower with five or six fans comfortably.
- Covers seven distinct fan sizes in one package
- Lowest per-screw cost among the multi-size options here
- Some owners report inconsistent thread depth on select screws from the batch
Skip this if your case uses rubber grommets or anti-vibration mounts — these are standard tapping screws and will not pair with those accessories.
Kernmax 507Pcs Professional Screws Assortment Kit
Targeted at system integrators and repair technicians, this 507-piece kit includes motherboard standoffs, SSD screws, hard drive screws, and fan screws in a single organizer. It is overkill for someone who only needs to replace two case fans, but ideal for a shop or a builder assembling from scratch.
- Complete hardware solution eliminates multiple separate purchases
- Sorted case keeps small fasteners accessible during assembly
- Bulk packaging adds weight and cost you will not use if you only need fan screws
Skip this if you already have a well-stocked hardware drawer or need only a handful of fan screws for a single upgrade.
30PCS Computer PC Fan Screws Kit
Designed for builders who need both long tapping screws (#6-32x30mm) for motherboard-adjacent fan positions and short M5x10mm screws for direct case mounts, this fifteen-and-fifteen split covers the two most common mounting scenarios in a single purchase. Stainless steel construction resists corrosion in humid environments.
- Stainless steel threads resist rust and stripping better than plated alternatives
- Dual-length design matches both common fan screw specifications
- Thirty pieces is tight for a case with more than five fans
Skip this if your build uses rubber grommet mounts or if you need more than thirty fasteners for a large multi-fan configuration.
Persberg 100pcs Cooling Fan Mount Screws (M5x10 Black)
For builders standardizing on M5 threads across 70mm to 140mm fans, Persberg delivers one hundred identical screws in black — enough to mount twenty-five fans with spares for replacement. The uniformity means you never waste time sorting by length or thread.
- Generous count handles large builds and provides a supply for future replacements
- Consistent M5x10 spec removes guesswork during installation
- Does not include longer screws for fan positions that pass through drive bays or thick brackets
Skip this if any of your fans mount with #6-32 threads or if you need varying screw lengths in one package.
Computer Case Fan Screws (20 Pack)
The entry point for pc fan screws on this list, this twenty-pack targets someone who has lost or stripped a single fan mount and needs a quick replacement without buying a hundred-piece kit. It covers the common 70mm through 140mm fan range at the lowest absolute price here.
- Lowest total cost of any option on this list
- Appropriate count for a one- or two-fan repair
- Plated steel rather than stainless, making it less durable over long thermal cycles
Skip this if you are building from scratch or need fasteners for anything beyond a simple replacement.
MroMax 34 Sets Cooling Fan Screws Kit (Black)
Thirty-four sets means thirty-four paired mounting solutions, each including both the screw and the rubber anti-vibration component that isolates fan noise from the case panel. This is the pick for silence-focused builds where grommet mounting matters as much as thread accuracy.
- Paired rubber grommets reduce vibration transfer for quieter operation
- Black tone finish blends with dark case interiors without visible contrast
- Higher per-mount cost than bare-screw alternatives
Skip this if your case uses direct metal-on-metal mounting or if you do not care about vibration isolation.
400PCS Screws Motherboard Standoffs Assortment Kit
Similar in philosophy to the Kernmax kit but with a broader component spread, this four-hundred-piece set includes standoffs, HDD, SSD, fan, power supply, and graphics card screws. It is the right call when you want one box that handles every fastener position from the case panel to the GPU bracket.
- Covers more motherboard and drive positions than any dedicated fan-only kit
- Universal compatibility across standard ATX and micro-ATX layouts
- Only a portion of the contents are fan-specific, so dedicated buyers pay for hardware they will not use
Skip this if you only need fan screws and already own the other hardware types in your collection.
80Pcs PC Fan Screws (#6-32x30mm + M5x10mm)
This kit is built for AIO cooler installations, where the radiator typically uses #6-32x30mm screws and the case fans mount with M5x10mm hardware. Thirty long screws and fifty short ones map directly to a 360mm AIO with six fans plus spares.
- Thread-and-length combination is pre-matched to common AIO mounting requirements
- Eighty pieces provides comfortable margin for multiple radiator positions
- Not optimized for builders who only mount standard case fans without a liquid loop
Skip this if your build is air-cooled and every fan uses the same thread specification.
Buying Guide
Thread Standard: #6-32 Versus M5
Case fan mounting screws come in two dominant thread standards. The #6-32 coarse thread (American) and the M5 metric thread (European) are not interchangeable. A screw that looks similar but has the wrong thread will either strip the fan frame or refuse to start. Check your fan specification sheet before buying. Multi-kit solutions that include both types in a single package remove the guesswork, especially for builders who mix fan brands across a single case.
Screw Length and Fan Position
Fan screws range from ten millimeters for a direct case-panel mount to thirty millimeters when the screw must pass through a drive cage, a thick bracket, or an AIO radiator. Using a screw that is too short leaves the fan unsupported at the far side; one that is too long can bottom out against the frame and crack plastic housings. Match length to the total material thickness at the mounting point, and buy kits that offer both options if your layout includes mixed positions.
Material and Finish
Stainless steel fasteners resist corrosion from internal humidity and do not gall or seize over repeated removal cycles. Plated carbon steel screws — common in the lowest-price options — can develop rust spots within months, especially in non-sealed case environments. For a one-time installation in a climate-controlled office, plated steel is acceptable. For gaming rigs, homelabs, or systems in coastal or high-humidity areas, the jump to stainless is worthwhile and only adds a marginal cost difference per screw.
Our Verdict
The Kernmax 507Pcs kit wins as the top overall pick because it eliminates the need for a second purchase and includes fan screws in proper context alongside every other fastener a build requires. For pure budget buyers who only need to secure a handful of fans, the Computer Case Fan Screws 20 Pack at $3.99 is the lowest-risk entry point, provided you do not expect long-term corrosion resistance. However, if your build is centered on an AIO liquid cooler, the 80Pcs PC Fan Screws kit wins outright because its 30mm long and 10mm short split matches radiator-and-fan mounting geometry precisely, making other options on this list a poor fit.
FAQ
What size screws are used for PC case fans?
Most case fans use either #6-32 or M5 thread screws, with lengths of 10mm or 30mm depending on the mounting surface thickness. The correct size depends on your specific fan and case, not on the fan diameter alone.
Can I use any screw to mount a PC fan?
No. Using the wrong thread will strip the fan frame threads or fail to engage properly, and an incorrect length can crack plastic housings or leave the fan inadequately secured. Always match the screw specification to the manufacturer’s documentation for your specific fan model.
Are fan screws different from other computer screws?
Fan screws are shorter and have a finer or coarser thread depending on the standard used, and they often feature a small head diameter to fit within the recessed mounting holes on fan frames. They differ from motherboard screws, which are typically longer and use a different head profile.
Do I need anti-vibration mounts with my fan screws?
Anti-vibration grommets or rubber washers reduce noise transfer from fan rotation into the case panel, which matters most in silence-oriented builds. They are optional for standard setups where fans operate at moderate RPM and case side panels already dampen some vibration.
