507Pcs Professional Computer Screws Assortment Kit, Includes Motherboard Screws, Standoffs, PC Case, SSD, Hard Drive, Fan, CD-ROM Screws
Quick take
This 507-piece PC screw assortment kit is built for everyday DIY PC builds and common repairs, covering motherboard hardware, standoffs, SSD and hard drive mounting screws, case screws, fan screws, and CD-ROM screws. It stands out for broad practical coverage and an organized storage box that makes it easier to find the right piece mid-build.
The main buying caveat is compatibility by threading and component brand. Some specialty parts (for example, certain fan systems) may require a screw type or threading not included.
Pros and cons
Pros
- Large 507-piece assortment aimed at frequent PC build and repair tasks (motherboard, standoffs, SSD, HDD, case, fan, and CD-ROM screws).
- Durable alloy steel screws with black oxide plating for corrosion and oxidation resistance.
- Organized, compartment-style storage box designed for quicker identification of screw sizes/types.
- Multiple screw head styles included to match different components’ fastening needs.
Cons
- Threading and part-specific standards vary, so a few specialty components may not match exactly (limited evidence of missing a screw type for at least one brand setup).
- There may be extra pieces included that are not useful for your specific build, so you still need to check what your case and components require.
- Includes washers, but washer sizes may not match every use case (some buyers may prefer using their own washers).
What buyers think
Buyer-review evidence is limited in volume, but the recurring themes are clear. The kit is consistently described as having “a lot of variety” and being genuinely handy for building and repair work, especially when you are missing a screw mid-project. Many buyers highlight that it includes commonly needed hardware for typical PCs, and that the value is strong when you only need one or two screws for the money. There are also mentions of sturdy screws that should hold up for standard installation use.
On limitations, one comment points to at least one screw type not being present for a particular fan threading standard, which suggests the assortment may not cover every niche or vendor-specific hardware convention. Another buyer notes washer sizing did not fit their need, indicating that washers may not be universally useful.
What this kit includes, and why it matters
This assortment focuses on the screws and standoffs you typically reach for when assembling a desktop PC or fixing something after the build. The kit is marketed as an all-in-one option that covers motherboard screws and standoffs, SSD mounting screws, hard drive mounting screws, PC case screws, PC fan screws, and CD-ROM screws. In practical terms, that means fewer “right now” trips to the hardware store when a stripped, missing, or mismatched screw slows you down.
Build quality and finish
The screws are made from alloy steel and finished with black oxide plating, which is intended to improve corrosion and oxidation resistance. That finish choice is a reasonable fit for PC cases where parts can be exposed to normal workshop humidity or occasional handling over time.
The kit also specifies a fine UNC thread size (#6-32) and uses fully threaded machine-screw style fasteners. If your PC hardware uses this common threading standard, you are likely to find many of the included screws match your needs.
Organization is part of the product value
A lot of screw kits look like “a bag of mixed fasteners,” which is frustrating when you are trying to complete an install quickly. This kit is supplied in a durable transparent storage box with clearly labeled compartments, designed to help you identify the right screw or standoff faster during building or repairs. That matters most for DIYers who assemble more than one system, do troubleshooting, or want an easier workflow.
Compatibility and fit: who this is for
This kit is best suited to buyers assembling or repairing a typical desktop PC where common mounting points (motherboard, drives, case fans, and case panels) use standard machine screw conventions. It is especially attractive if you want a single starter assortment rather than buying separate bags of motherboard screws, standoffs, and drive/case fasteners.
Who should buy it
- You build PCs as a hobby and want an “always have it on hand” screw kit for replacements.
- You do occasional repairs, upgrades, or cable and hardware changes and expect to reuse mounting hardware frequently.
- You prefer organized storage that makes it easier to find the right screw type mid-build.
Who should avoid it (or double-check first)
- Your components or aftermarket hardware use special threading standards or vendor-specific screw types that may not align with #6-32 UNC.
- You need a very specific screw type or washer size for a niche mounting scenario, and you want guaranteed one-to-one match without any substitutions.
Pros and cons recap
- Key advantage: broad practical coverage for common PC building and repairs, plus organized storage.
- Key tradeoff: like most assortment kits, it may not match every vendor-specific fan, panel, or mounting standard perfectly.
- Best use case: DIY desktop builds, upgrades, and keeping a replacement hardware kit ready.
Verdict
If you want a single, organized kit that covers many of the screws and standoffs used in standard desktop PC builds and maintenance, the 507-piece assortment is a strong fit. The black oxide, alloy steel construction and #6-32 UNC focus support dependable everyday use, and the compartment box helps reduce build-time friction. Just be prepared to verify threading and component-specific requirements before assuming every screw will match, especially for specialty fans or hardware.
FAQ
What thread size does this PC screw kit use?
The kit is specified for #6-32 thread size (UNC), which is a common desktop PC fastener standard. Still, it is smart to compare against the threading required by your specific case, motherboard, and components.
Does it include motherboard standoffs and drive mounting screws?
Yes. The kit is designed to include motherboard screws and standoffs, along with SSD and hard drive mounting screws for typical desktop installation points.
Will it fit every motherboard and PC case?
It is intended for broad compatibility with standard components, but universal fit is never guaranteed across every vendor or specialty part. Some buyers report missing a screw type for a specific setup, which suggests you should confirm your component’s required screw style and threading.
Is the storage box useful or just extra packaging?
The organized, compartment-style transparent box is part of the kit’s value. It is meant to help you quickly identify the right screw or standoff during a build or repair instead of sorting through a mixed pile.
Are washers included?
Washers are included, but washer sizing may not match every use case. If you have a specific washer requirement, you may need to use washers you already have.
