#4 x 1/2″ Pan Head Phillips Screws — 100 Pack (304 Stainless)
Material: 304 stainless steel provides superior corrosion resistance, ideal for moisture-prone environments or outdoor projects. Type: Pan Head Phillips Screws with a standard drive. Screw Size: #4 x 1/2″. These screws are suited for sheet metal and light fabrication tasks where a reliable, rust-resistant fastener is required.
#4 x 3/8″ Pan Head Screws — 100 Pack (Black Oxide 304)
Material: Black Oxide 304 stainless steel for corrosion resistance with a darker finish. Type: Pan Head Sheet Metal Screws, Phillips Drive, Self-Tapping. Screw Size: #4 x 3/8″. Suitable for metal-to-wood or metal-to-metal assemblies where a flush head is preferred and rust resistance matters.
#4 x 1/2″ Pan Head Screws — 100 Pack (Black Oxide 304)
Material: Black Oxide 304 stainless steel for corrosion resistance. Type: Pan Head Sheet Metal Screws with Phillips drive and self-tapping capability. Screw Size: #4 x 1/2″. Great for wood-to-metal or sheet metal assemblies where a robust, rust-resistant fastener is needed.
HELIFOUNER 240 Pieces #4-40 Pan Head Machine Screws Assortment Kit
Sizes cover a range including #4-40×3/16″ to #4-40×1/2″ with multiple lengths. Material: 304 stainless steel. This kit provides fully machine-threaded, pan head screws with matching hex nuts in a compact storage box, useful for hardware projects and prototyping where a consistent machine screw presence is needed.
#4 x 3/4″ Pan Head Sheet Metal Screws — 100 Pack (304 Stainless)
Material: 304 stainless steel offers strong corrosion resistance. Type: Pan Head Sheet Metal Screws, Phillips drive, self-tapping. Screw Size: #4 x 3/4″. Applications include wood and metal fastening, outdoor furniture, and metal-to-wood assemblies where a longer pan head is advantageous for surface area and grip.
Buying Guide: Key Considerations For #4 Pan Head Screws
Material and finish: Stainless steel (304) provides excellent corrosion resistance for indoor and outdoor projects. Black oxide finishes offer a darker aesthetic and decent rust resistance, but are not as corrosion-resistant as stainless steel in harsh environments. Consider whether you need self-tapping capability for metal or sheet metal projects, or machine-thread compatibility for precision assemblies.
Head style and drive: Pan head screws distribute load over a broad surface, reducing pull-through on softer materials. Phillips drive is common and user-friendly, but square drive or Hex recommendations may apply for high-torque tasks or automated assembly. Ensure the head height fits your material thickness and any countersinking requirements.
Length and diameter: The #4 size is precise for light-to-medium fastening. Choose lengths from 3/8″ to 3/4″ depending on material stack-up. For thicker assemblies, a longer screw may be necessary; for cosmetic or flush installations, a shorter screw can prevent protrusion.
Environment and application: For outdoor or humid settings, prioritize corrosion resistance (stainless steel). For interior projects, black oxide offers a pleasant finish with adequate durability. Self-tapping screws work best when threading into metal or hard materials without pre-drilling; for softer woods, match the screw type to avoid splitting.
Availability and packaging: Pack sizes vary (100 or 240 pieces). Larger packs are cost-effective for ongoing projects, but smaller kits may be preferable for specific tasks or limited toolsets. When selecting, balance project scope with the need for consistent sizing and finish.
Compatibility: If your project uses machine screws, ensure thread pitch and length align with nuts or tapped holes. For sheet metal work, confirm that the screw is designed for sheet metal use and will not strip or deform the material.
