The brass construction provides excellent corrosion resistance and a warm gold tone that complements both silver and black hardware.

Key Specifications

Why Choose Brass Pineapple Thumb Nuts?

• Tool-free installation — hand-tighten PC fans and radiators without a screwdriver; ideal for frequent fan swaps and maintenance
• Premium aesthetic — warm gold brass tone adds a distinctive accent to custom PC builds and water cooling loops
• 5pcs pack — sufficient for one 120mm or 140mm fan (4 screws) with one spare

Frequently Asked Questions

Q: What thread size are these thumb nuts?

A: Check the specific variant listing for the thread size. PC fan mounting typically uses a self-tapping fan thread or M3 metric thread. Verify your fan frame thread before ordering.

Q: Will brass thumb nuts corrode inside a PC case?

A: No. Brass is inherently corrosion-resistant and will not rust inside a PC case. The warm gold tone will remain stable over time without tarnishing in a dry indoor environment.

Q: Can I use these for all four fan mounting positions?

A: Yes. The 5pcs pack provides 4 thumb nuts for one fan plus one spare. For a 3-fan radiator (12 screws), order 3 packs.
