6-32 x 1/4" Aluminum Knurled Thumb Screws for PC Case & DIY Builds

These are 6-32 x 1/4" thumb screws:

• 6-32 UNC thread — approximately 3.5mm (0.138") nominal diameter, 32 threads per inch.
• 1/4" shank length — approximately 6.35mm, the standard engagement depth for PC case panels and brackets.

This is the industry-standard size for desktop PC cases. They fit ATX, Micro-ATX, Mini-ITX, and most server chassis expansion card slots, side panels, and drive brackets with standard 6-32 tapped holes.

In most cases, yes. The 6-32 UNC thread is the standard fastener size used in the vast majority of desktop PC cases from major brands (Corsair, NZXT, Fractal Design, Lian Li, Phanteks, etc.) as well as generic ATX enclosures. These are a direct drop-in replacement for the Phillips or slotted 6-32 machine screws that typically ship with your case. If you're unsure, check your case manual or measure the existing screws.

These thumb screws are made from aluminum alloy. Aluminum is lighter than steel but generally softer, so it's important to hand-tighten only — do not use a screwdriver or power tool on these. Over-torquing can strip the threads. For PC case applications, finger-tight is typically sufficient and recommended. The knurled head is designed to give you enough grip to achieve a secure, rattle-free fit without tools.

These are designed for light-duty hand-tightening applications — PC case panels, expansion card brackets, and drive cages. They are not rated for high-torque or structural load-bearing use. In a typical PC build, hand-tight is generally sufficient to keep panels secure and rattle-free during normal desktop use and transport.

These thumb screws are primarily designed for indoor use in PC builds and electronics enclosures. Aluminum alloy generally offers good resistance to light moisture and oxidation, and the anodized finish provides minor additional surface protection. For prolonged outdoor or high-humidity exposure, we recommend confirming suitability for your specific environment before ordering in bulk.

No. All 11 color options share the same 6-32 x 1/4" thread specification. The colors are achieved through an anodizing or surface coating process and are purely aesthetic. They do not affect thread pitch, diameter, or shank length. You can mix colors across your build without any compatibility concerns.

It depends on your case and configuration, but generally:

• Side panels: typically 2–4 screws per panel
• Expansion card brackets: 1 screw per slot cover or installed card
• Drive brackets and cages: varies by case design

A typical ATX build generally uses 6–12 thumb screws total. The 10-piece pack is a good starting point for a single build; the 25-piece pack works well if you're building multiple systems or want spares on hand.

Absolutely. Each color is available in a pack quantity of 1, so you can order a single screw to verify the color match and thread fit before committing to a larger quantity. This is especially useful if you're trying to match an existing color scheme or confirm clearance in a tight case layout.
