#8-32 Phillips Pan Head Machine Screws — Six Finishes, One Reliable UNC Thread
When you need a machine screw that clamps firmly, installs fast, and matches the finish of your project — whether it’s a brushed-nickel appliance panel, a zinc-coated electrical enclosure, or a colour-coded assembly line fixture — a one-size-fits-all fastener won’t cut it. These #8-32 Phillips pan head machine screws are available in six distinct plating finishes so you can match the fastener to the job, not the other way around.
Each pack contains 100 pieces of #8-32 UNC Phillips pan head machine screws in your selected size and finish. Screws are manufactured from carbon steel with electroplated finishes available in White Zinc, Blue Zinc, Blue-White Zinc, Green Zinc, Bright Nickel, and Coloured Zinc. The pan head profile features a low, rounded dome that sits above the surface without requiring a countersunk hole. Lengths range from 5/16” to 1-1/2” with shank diameters varying by variant — see variant options for exact dimensions.
These pan head machine screws are well suited for electronics and appliance assembly where a visible, above-surface fastener head is acceptable and a larger bearing surface is needed; electrical panel and enclosure fabrication where finish matching or colour-coding is required; and general mechanical assembly in workshops and light manufacturing where #8-32 UNC machine screws are the standard specified fastener.
🔩
Thread Compatibility: #8-32 UNC (Unified National Coarse) — 32 threads per inch, major diameter ≈0.164” (4.17mm). Compatible with standard #8-32 UNC nuts, threaded inserts, and tapped holes per ASME B1.1. Phillips PH2 driver recommended.
✅ Key Features of These #8-32 Phillips Pan Head Machine Screws
-
🌟Six Plating Finishes Available — Choose from White Zinc, Blue Zinc, Blue-White Zinc, Green Zinc, Bright Nickel, or Coloured Zinc to match your project’s aesthetic or corrosion requirements — a versatility rarely found in a single pan head machine screw listing.
-
🔴Pan Head Profile — No Countersinking Required — The low dome head sits above the material surface and provides a wide bearing area, making installation faster and simpler than countersunk styles in applications where a flush finish is not needed.
-
✚️Phillips PH2 Drive — Compatible with standard PH2 bits and power drivers for fast, consistent installation across bulk fastening tasks in electronics, appliances, and UNC machine screw assemblies.
-
⚙️#8-32 UNC Thread — Industry Standard — One of the most widely used machine screw sizes in US manufacturing; fits off-the-shelf #8-32 nuts, threaded inserts, and pre-tapped holes without custom tooling.
-
📦100-Piece Bulk Packs — Each pack contains 100 screws, sized for production runs, workshop stock, and repair kits where consistent supply of zinc plated pan head screws is needed.
-
📐Multiple Lengths Available — Lengths from 5/16” to 1-1/2” cover a wide range of material thicknesses, from thin sheet metal and PCB standoffs to thicker bracket and enclosure assemblies.

❓ Frequently Asked Questions
How do I choose the right length for a #8-32 pan head machine screw?
A general rule is to select a length that provides at least one screw diameter (approximately 0.164” for #8) of thread engagement in the receiving material, plus the thickness of the part being clamped. Available lengths in this listing range from 5/16” to 1-1/2”. For example, fastening a 1/4” panel typically calls for a 3/8” or 1/2” length.
What is the difference between a pan head and a flat head (countersunk) screw?
A pan head screw has a low, rounded dome profile that sits above the surface of the material. It does not require a countersunk hole and provides a larger bearing surface than a flat head. A flat head (countersunk) screw tapers to sit flush with or below the surface. Pan heads are generally preferred when a flush finish is not required and a larger clamping area is beneficial.
Which finish should I choose — white zinc, blue zinc, green zinc, nickel, or coloured zinc?
White zinc (clear zinc) and blue-white zinc offer a bright silver appearance and moderate corrosion resistance for indoor use. Blue zinc provides a distinctive blue-tinted finish with similar protection. Green zinc (yellow chromate) generally offers slightly better corrosion resistance than clear zinc. Bright nickel gives a polished silver look often used in decorative or visible applications. Coloured zinc is typically used for colour-coding or aesthetic matching. For outdoor or high-humidity use, green zinc or nickel are generally preferred over white zinc.
How strong are carbon steel #8-32 machine screws?
Carbon steel machine screws typically meet property class 4.8 or SAE Grade 2 strength levels, with tensile strengths generally ranging from 420 to 520 MPa depending on the specific production batch. For load-critical or structural applications, please contact us to confirm the exact grade before ordering.
Can these screws be used outdoors?
Zinc-plated and nickel-plated carbon steel screws provide moderate corrosion resistance suitable for indoor and light sheltered applications. For prolonged outdoor exposure or high-humidity environments, green zinc (yellow chromate) or nickel finishes generally offer better protection than white or blue zinc. For marine or heavily corrosive environments, stainless steel fasteners are typically recommended.
What thread standard does #8-32 use, and what nuts or inserts are compatible?
#8-32 is a Unified National Coarse (UNC) thread with 32 threads per inch and a major diameter of approximately 0.164” (4.17mm). It is compatible with standard #8-32 UNC nuts, threaded inserts, and tapped holes per ASME B1.1. This is one of the most common machine screw sizes in US electronics and appliance assembly.
What driver bit do I need for a Phillips pan head #8-32 screw?
A Phillips PH2 bit is typically used for #8-32 pan head machine screws. Using the correct bit size is important to avoid cam-out and head damage, especially when driving with a power tool at higher torque settings.
