Self Tapping Screws
304 Stainless Steel Self Tapping Screws Pan Head Phillips Fine Thread For Electronics Enclosure Assembly
Three decisions – one right screw
Choosing the right self tapping screw comes down to three simple decisions. Answer these, and you will pick the perfect screw every time.
Decision 1 – What material are you fastening?
| Your material | What you need | Why |
|---|---|---|
| Thin metal sheet (0.5‑2mm) | Fine thread, sharp point | More threads per inch = stronger hold |
| Wood (soft or hardwood) | Coarse thread, flat head | Bites fast, sits flush |
| Plastic / PVC | Wafer head, thread forming | Wide clamp, no cracking |
| Trailer flooring | Hex head, heavy duty galvanized | High torque, rust protection |
| Electronics enclosure | Pan head, stainless steel | Clean appearance, corrosion resistant |
Decision 2 – Which head shape?
| Head shape | Best for |
|---|---|
| Flat head | Flush mounting. Screw sits level with the surface. Finished panels, furniture. |
| Wafer head | Low profile, wide clamp. Pocket holes, thin sheet metal. |
| Pan head | General purpose. Most common choice for assembly work. |
| Hex head | High torque. Use a wrench. Metal framing, heavy duty. |
| Countersunk | Sits completely below the surface. Smooth finish required. |
| Truss head | Wide, low profile. Spreads pressure on soft materials. |
Decision 3 – Which thread type?
| Thread type | Best for |
|---|---|
| Fine thread | Thin metal, hard plastics. More holding power. |
| Coarse thread | Wood, soft plastics. Faster engagement. |
| Thread forming | Plastics. Forms threads without cutting. No chips. |
| Thread cutting | Metal. Cuts threads. Requires less torque. |
Materials available
| Material | Best for |
|---|---|
| 304 stainless steel | Outdoor, wet, general rust protection |
| 316 stainless steel | Marine, saltwater, chemical exposure |
| Brass | Non‑magnetic, decorative, electronics |
| Zinc plated steel | Cost effective, light outdoor |
| Aluminium | Lightweight, non‑magnetic |
| Black oxide | Matte finish, indoor use |
