How much vibration reduction do the O-rings provide?

The rubber O-rings act as a mechanical buffer between the screw head and the metal chassis, absorbing micro-vibrations from fans, HDDs, and PSUs. Users typically notice a measurable reduction in resonance noise, especially in builds with multiple spinning drives or high-RPM fans.

Are these screws suitable for long-term use without loosening?

Yes. The screws are self-locking by design and made from Grade 8.8 carbon steel, which provides reliable clamping force. The O-ring also adds slight friction that helps resist loosening from vibration over time.

PC Case Screws with Shock-Absorbing O-Rings — Stop Fan Noise and Drive Vibration for Good

If your PC hums, rattles, or resonates every time a fan spins up or a hard drive seeks, the culprit is almost always metal-on-metal contact at the screw points. Builders, modders, and anyone running a multi-drive workstation know how frustrating it is to track down that persistent buzz — only to find it's coming from a GPU bracket or PSU mount with no vibration isolation at all.

This listing offers three purchase options — sold individually per 100-piece pack, so you can buy exactly what you need:

O-Ring Only — 100× shock-absorbing rubber O-rings (M4 × 8 × 2mm, black). Use these to upgrade screws you already have.
Screw Only — 100× #6-32 × 6mm (≈1/4″) hex screws or hand-tight thumb screws, available in black oxide or nickel-plated silver. No O-rings included.
Screw + O-Ring Combo — 100× screws paired with 100× matching O-rings in one pack. Everything you need to fully dampen a screw point, ready to install.

All screws share the #6-32 UNC thread standard and a 6mm (≈1/4″) shank length. These are the go-to fasteners for PC case vibration dampening in ATX tower builds, silent HTPCs, and noise-sensitive workstations — equally useful for 3.5″ HDD anti-vibration mounting, GPU bracket screw replacement, and PCI slot cover fastening.

🔧 Compatibility: Fits standard #6-32 UNC threaded standoffs and panels found in ATX, Micro-ATX, and Mini-ITX cases. Compatible with GPU brackets, PSU mounts, 3.5″ HDD bays, PCI slot covers, and side panels from most major PC case brands.

✅ Key Features of These PC Case Vibration-Dampening Screws

🛡️Shock-Absorbing Rubber O-Rings — Each O-ring (M4 × 8 × 2mm) is made from durable rubber that cushions the screw head against the chassis, reducing resonance from HDDs, PSUs, and case fans in vibration-dampening PC builds.
⚙️Industry-Standard #6-32 UNC Thread — The #6-32 thread is the universal standard for PC case fasteners, ensuring drop-in compatibility with GPU brackets, power supply mounts, and PCI slot covers without any modification.
💪Grade 8.8 Carbon Steel Construction — Hex screws are manufactured from carbon steel at Grade 8.8 strength, delivering reliable clamping force and resistance to stripping — even after repeated removal during builds and upgrades.
🎨Two Finish Options for Any Build Aesthetic — Choose black oxide for a stealthy, all-black interior look, or nickel-plated silver for a classic chrome finish. Both finishes provide a layer of corrosion resistance for long-term indoor use.
🖐️Tool-Free Thumb Screw Option — The hand-tight thumb screw variant lets you secure side panels and frequently accessed components without reaching for a screwdriver, ideal for open-bench setups and regular maintenance builds.
📦Buy Only What You Need — 100pcs Per Pack — Choose O-rings only, screws only, or a full screw + O-ring combo. A single 100-piece pack covers an entire ATX build with spares, so you can replace every screw point with proper PC case anti-vibration hardware in one order.

❓ Frequently Asked Questions

What size are these PC case screws?

These are #6-32 UNC screws — the standard thread used in the vast majority of PC cases worldwide. The shank length is 6mm (≈1/4″), which is the standard length for GPU brackets, PSU mounts, 3.5″ HDD bays, and PCI slot covers. If your case uses #6-32 standoffs (which most ATX, Micro-ATX, and Mini-ITX cases do), these will fit directly.

What is the O-ring made of and how thick is it?

The O-rings are made from durable rubber and measure M4 × 8 × 2mm (inner diameter × outer diameter × thickness). The 2mm rubber layer sits between the screw head and the chassis surface, absorbing micro-vibrations and providing a degree of electrical insulation between the fastener and the panel.

Will these screws fit my PC case?

In most cases, yes. The #6-32 UNC thread is the industry-standard for PC case fasteners and is compatible with cases from NZXT, Fractal Design, Corsair, Lian Li, Phanteks, Cooler Master, and most other major brands. If you're unsure, check your case manual or measure the existing screws — a 3.5mm thread diameter and 6mm length is the standard.

What is the difference between the Black and Silver hex screws?

Both are functionally identical #6-32 hex screws made from Grade 8.8 carbon steel. The Black version has a black oxide finish for a stealthy, all-black interior aesthetic. The Silver version is nickel-plated for a classic chrome look. Choose based on your build's color scheme — performance and thread spec are the same.

Do I need a screwdriver for the thumb screws?

No. The hand-tight thumb screws feature a knurled head designed for tool-free installation. They're ideal for side panels, top mesh covers, or any component you access regularly. They can generally be tightened to a secure fit by hand, though a light assist with a driver is fine if you prefer extra torque.

How much vibration and noise reduction can I expect from the O-rings?

The rubber O-rings act as a mechanical buffer between the screw head and the metal chassis, absorbing micro-vibrations from spinning components like HDDs, PSUs, and case fans. Users typically notice a measurable reduction in resonance and low-frequency hum, especially in builds with multiple 3.5″ drives or high-RPM fans. Results vary by case material and component load.

Are these screws self-locking? Will they loosen over time?

Yes. The screws use a self-locking thread design that resists loosening under vibration. The Grade 8.8 carbon steel provides reliable clamping force, and the O-ring adds slight friction that further helps maintain tension. For long-term builds, these are generally more vibration-resistant than standard smooth-shank screws.

Can I use these screws for outdoor or high-humidity environments?

These screws are designed for indoor PC case use. The black oxide and nickel-plated finishes provide a basic level of corrosion resistance suitable for typical indoor environments. They are not recommended for outdoor use or high-humidity applications. For outdoor or marine environments, stainless steel fasteners would be a more appropriate choice.
