🔩 #6-32 UNC Countersunk Phillips Screws – Carbon Steel, 5/6/8mm Lengths for Computers, Toys & Furniture

You're fixing a loose hinge on a wooden cabinet, mounting a circuit board in a PC case, or repairing a fishing reel – and you need small, reliable screws that sit flush. These #6-32 UNC countersunk machine screws are made from carbon steel with a Phillips drive. The flat head sinks perfectly into a pre‑drilled countersink, leaving a smooth, snag‑free surface. Choose from 5mm, 6mm, or 8mm overall lengths. The #6-32 thread is a standard US coarse size, widely used in electronics, hobby projects, and furniture assembly. Keep a stash in your workshop for all those little repairs where a flush finish and dependable strength matter.

✨ Key Features – #6-32 UNC Countersunk Phillips Screws

🔽 Countersunk flat head (82° typical for UNC) – Sits flush with the surface after countersinking. Ideal for smooth, professional finishes on wood, plastic, and sheet metal.
🎨
Phillips drive – Standard cross recess works with common screwdrivers and bits. Good torque transfer without slipping.
📏 #6-32 UNC thread – Unified National Coarse – 6 gauge diameter, 32 threads per inch. Widely used in North American electronics, appliances, and light machinery.
📐 Three compact lengths – 5mm, 6mm, or 8mm overall (including head). Perfect for shallow holes, thin panels, and small assemblies.
💪 Carbon steel construction (Grade 5 equivalent) – Strong and durable. Provides good tensile strength for most light‑duty fastening applications.
🎨 Clean, uniform appearance – Smooth finish blends well with different surfaces. Works in computer cases, toys, motorcycles, fishing gear, and furniture.

❓ Frequently Asked Questions – #6-32 UNC Countersunk Screws

1. Do I need to countersink the hole for these screws to sit flush?

Yes – these are 82° countersunk screws (the standard for UNC threads). To achieve a flush finish, drill a matching countersink hole using an 82° countersink bit. In soft wood or plastic, you can gently tap the head in, but proper countersinking gives the best result.

2. What is the difference between #6-32 and metric M3.5 screws?

#6-32 is a US coarse thread (0.138" diameter, 32 TPI). M3.5 is metric (3.5mm diameter, 0.6mm pitch ≈ 42 TPI). They are not interchangeable. #6-32 is very common in North American electronics, appliances, and furniture; M3.5 is more common in European and Asian products. Always match the thread type.

3. Will these carbon steel screws rust?

Yes – carbon steel will rust if exposed to moisture. These screws are best for indoor applications or dry environments. If you need corrosion resistance for outdoor or marine use, choose stainless steel or apply a protective coating (paint, oil, or zinc plating). We offer plated versions – please contact us.

4. Can I use these screws with a nut? What nut fits #6-32?

Yes – these are machine screws. Use a standard #6-32 UNC hex nut or lock nut. They will also thread into pre‑tapped #6-32 holes. They are not self‑tapping, so for wood or plastic, drill a pilot hole and use a threaded insert or nut on the back.

5. What Phillips screwdriver size should I use?

For #6-32 screws, a #1 Phillips screwdriver is typically the best fit. A #0 may work but can slip; a #2 is too large. Use a quality driver that matches the recess to avoid cam‑out and head damage.

6. Are these screws fully threaded? The lengths are very short.

Yes – with overall lengths of only 5, 6, or 8mm, these screws are fully threaded from under the head to the tip. This gives maximum grip even in shallow holes.
