🔧 Product Overview: 6#32 x 6.5mm High‑Type Knurled Thumb Screws – Aluminum Alloy Hand Grip Knob Bolts for PC Cases
Upgrade your computer case or DIY project with these high‑type knurled thumb screws. Made from lightweight, corrosion‑resistant aluminum alloy, they feature a tall knurled head that provides excellent finger grip and leverage for tool‑less hand tightening and loosening. The 6#32 UNC thread is the standard size for many PC case side panels, hard drives, optical drives, graphics cards, and expansion cards. With a 6.5mm thread length (measured under the head), they are ideal for standard panel thicknesses. The anodized finish offers good oxidation and corrosion resistance, while the knurled grip makes installation and removal quick and easy – no screwdriver needed. Perfect for PC builders, modders, and anyone who frequently accesses their computer components.
✨ Why These High‑Type Knurled Thumb Screws Are a PC Modder's Essential
-
High‑type knurled head – Taller than standard thumb screws, providing more gripping surface and extra leverage for hand tightening.
-
Lightweight aluminum alloy – Strong yet lightweight, reduces overall case weight. Excellent corrosion and oxidation resistance.
-
Tool‑less operation – The diamond knurl pattern gives you a secure, non‑slip grip – no screwdriver or wrench needed.
-
Standard 6#32 UNC thread – Industry standard size for PC case side panels, hard drives, optical drives, network cards, graphics cards, and sound cards.
-
6.5mm thread length (under head) – Ideal for standard PC panel thickness (0.8–1.2mm steel) plus enough thread engagement for secure fastening.
-
Anodized finish – Provides a durable, attractive surface with good corrosion and oxidation resistance. Available in multiple colors (select from options).
-
Wide applications – Computers, chassis side panels, hard drives, optical drives, network cards, graphics cards, sound cards, DIY modifications and refits.

❓ FAQs – 6#32 Knurled Thumb Screws
🔸 Will these screws fit my computer case?
Most standard PC cases use 6#32 UNC threads for side panels, power supplies, and drive bays. The 6.5mm thread length is ideal for typical panel thickness (0.8–1.2mm steel). If your case uses metric threads (e.g., M3), these will not fit. Check your existing case screws – if they say #6-32, they will fit perfectly.
🔸 How is thread length measured? Is 6.5mm long enough?
Thread length is measured from the underside of the head to the tip. The 6.5mm threaded shank is designed for standard PC panel thickness (1–2mm) plus the threaded hole depth (typically 4–5mm deep). It provides adequate thread engagement without bottoming out. For thicker panels or custom applications, consider a longer thread length.
🔸 Will the anodized color wear off?
Anodizing is an electrochemical process that creates a durable oxide layer bonded to the aluminum. It will not peel like paint. Under normal hand use, the color will remain vibrant for years. Heavy abrasion may wear the finish, but typical PC case thumb screws are handled gently.
🔸 What is the advantage of the “high‑type” head?
The high‑type head is taller than standard knurled thumb screws, giving you more surface area for your fingers and better leverage. This makes it easier to apply torque by hand – especially useful for tight screws or when you need a secure hold.
🔸 Can I use these screws with nuts, or are they for threaded holes only?
These are standard machine screws – they work with matching 6#32 nuts or in pre‑tapped holes. Most PC cases have threaded holes, so nuts are typically not needed. For through‑hole applications, use a 6#32 nut on the back side.
🔸 Are these screws magnetic?
Aluminum is non‑magnetic, so these thumb screws will not interfere with sensitive electronics or hard drives. They are completely safe for use inside a computer case.
