Phillips Pan Head Machine Screws with Washer — Nickel Plated, M2 to M4

Whether you're assembling electronics enclosures, securing sheet metal panels, or building out a DIY project that demands a clean, flush finish, finding the right small-diameter machine screw in the right quantity shouldn't slow you down. Hobbyists, makers, and small-batch manufacturers alike know the frustration of running short mid-project or overpaying for hardware store minimums.

Each set consists of Phillips pan head machine screws with an integrated washer flange, finished in nickel plating for a bright, uniform appearance. Available in metric thread diameters M2 (2mm / ≈5/64"), M2.5 (2.5mm / ≈3/32"), M3 (3mm / ≈1/8"), and M4 (4mm / ≈5/32"), with shank lengths ranging from 4mm (≈5/32") up to 50mm (≈2") — all lengths measured excluding the head. Pack quantities run from 10 pieces up to 2,000 pieces so you can order exactly what your job requires.

Typical use cases include securing PCB standoffs and electronics chassis panels, fastening thin-gauge sheet metal in HVAC and appliance fabrication, assembling plastic enclosures and 3D-printed parts where a washer flange prevents pull-through, and general machine assembly where a Phillips pan head machine screw with washer provides a low-profile, tool-friendly finish.

🔩 Compatibility: ISO metric thread standard — M2, M2.5, M3, M4. Not compatible with UNC/UNF inch-series threads. Confirm thread pitch of your tapped hole or nut before ordering.

✅ Key Features of These Phillips Pan Head Machine Screws with Washer

  • ⚙️Nickel Plated Finish — Bright nickel coating provides a uniform, corrosion-resistant surface well-suited for indoor electronics, appliance, and light industrial assembly applications.
  • 🔩Integrated Washer Flange — The built-in washer distributes clamping load across a wider footprint, reducing pull-through risk in plastic and thin sheet metal without needing a separate flat washer.
  • 📐Wide Size Range — Covers M2 through M4 thread diameters and lengths from 4mm to 50mm (≈5/32" to 2"), making these Phillips pan head machine screws with washer suitable for a broad range of fastening tasks.
  • 🔧Phillips Drive Compatibility — Standard cross-head recess works with PH0 (M2–M2.5) and PH1 (M3–M4) bits, compatible with both manual screwdrivers and power tools for faster assembly.
  • 📦Flexible Pack Quantities — Order from 10 pieces for prototyping up to 2,000 pieces for production runs, with per-unit cost decreasing at higher quantities — ideal for bulk machine screw purchasing.
  • 🏭ISO Metric Thread Standard — Manufactured to standard metric thread specifications, ensuring consistent fit with metric nuts, tapped holes, and threaded inserts used in electronics and machine assembly worldwide.

❓ Frequently Asked Questions

How do I choose the right length for these screws?

A general rule is to select a length that allows at least 1.5× the thread diameter of engagement into the receiving material. For example, an M3 screw threading into aluminum should typically engage at least 4.5mm (≈3/16"). The listed length excludes the head, so factor in any clearance holes or stacked materials. When in doubt, size up.

What is the load-bearing or clamping strength of these screws?

Exact tensile and shear values depend on the base material and thread engagement depth. These are generally suitable for light-to-medium duty fastening in electronics enclosures, sheet metal, and plastic assemblies. For structural or high-vibration applications, consult an engineer and verify the specific grade.

Can these screws be used outdoors or in humid environments?

The nickel plating provides moderate corrosion resistance suitable for indoor and sheltered applications. For prolonged outdoor exposure or marine environments, stainless steel fasteners are generally recommended. If used outdoors, applying a thread sealant or anti-corrosion compound can extend service life.

What thread standard do these screws follow, and are they compatible with my existing hardware?

These screws follow the ISO metric thread standard (M2, M2.5, M3, M4). They are not compatible with UNC/UNF inch-series threads. Always verify the thread pitch of your receiving nut or tapped hole matches the metric standard before installation.

Why does a pan head screw have a washer built in — do I still need a separate washer?

The integrated washer flange distributes clamping load over a larger surface area, reducing the risk of the head pulling through softer materials like plastic or thin sheet metal. In most cases you do not need a separate flat washer, which saves assembly time and reduces part count.

What screwdriver bit size do I need for M2, M3, and M4 Phillips screws?

For M2–M2.5 screws, a PH0 (Phillips #0) bit is typically the correct fit. For M3–M4, a PH1 (Phillips #1) bit is generally recommended. Using an oversized bit can strip the recess, so always match the bit size to the screw diameter.

How do I convert the listed metric lengths to inches?

Divide the millimeter value by 25.4. Quick reference: 4mm ≈ 5/32", 6mm ≈ 1/4", 8mm ≈ 5/16", 10mm ≈ 3/8", 12mm ≈ 15/32", 16mm ≈ 5/8", 20mm ≈ 25/32", 25mm ≈ 1", 30mm ≈ 1-3/16", 40mm ≈ 1-9/16", 50mm ≈ 2".
