🔩 Pan Head Self‑Tapping Screws with Fixed Washer – A2 Stainless Steel (M1.2–M5)

Get the holding power of a pan head with the load‑spreading advantage of a built‑in washer — that's exactly what these PWA pan head self‑tapping screws deliver. The fixed washer remains stationary as you tighten, distributing clamping force across a wider area than a standard flange while protecting the material surface from scratches and galling. Manufactured from genuine A2 / 304 stainless steel, each screw provides permanent corrosion resistance for outdoor, humid, and mild chemical environments without a surface coating that can wear thin. The sharp, fully‑threaded self‑tapping shank cuts its own path into sheet metal, plastic, wood, and composites — no pre‑tap or pilot hole needed in materials up to 0.025″ (0.6 mm) thick. With nine exact metric diameters from M1.2 to M5 and all dimensional data clearly specified, this series covers everything from micro‑electronics to medium‑duty fabrication where a clean, secure joint matters.

⚙️ Key Features – PWA Pan Head Self‑Tapping Screws with Washer

  • Genuine A2 / 304 stainless steel – permanent rust protection with good chemical resistance; slightly magnetic after cold working
  • Integrated fixed washer stays stationary during tightening, spreading the load, and preventing surface scratches
  • Self‑tapping thread cuts cleanly into sheet metal, plastic, wood, and composites – no pre‑drilling in thin materials
  • Phillips pan head with washer provides a clean, finished appearance and secure, cam‑out‑resistant drive
  • Nine precise metric diameters: M1.2, M1.4, M1.7, M2, M2.3, M2.6, M3, M4, M5 – a size for every light‑ to medium‑duty job
  • Head height includes the washer; length measured from the bearing surface for exact material thickness matching
  • Ideal for electronic enclosures, appliance panels, automotive trim, outdoor fixtures, and visible assemblies

❓ Frequently Asked Questions – PWA Pan Head Screws with Washer

🔸 Does the washer spin freely, or is it fixed?

The washer is fixed and remains stationary as you tighten. This prevents the washer from spinning against the material surface, which protects against scratching, marring, and galling — especially important on painted, coated, or polished surfaces.

🔸 How does the length measurement work for these screws?

Length is measured from the bearing surface (the underside of the fixed washer) to the tip of the thread. Head height and washer thickness are not included, so you can accurately match the threaded portion to your material thickness.

🔸 Can these screws be used outdoors without rusting?

Yes. A2 / 304 stainless steel is designed for outdoor, marine‑above‑waterline, and humid environments. It resists red rust effectively and will not corrode like plated carbon steel. For permanent saltwater submersion, 316 (A4) is recommended.

🔸 Do I need a pilot hole for these self‑tapping screws?

In thin sheet metal up to about 0.025″ (0.6 mm), soft plastics, and wood, you can drive them directly. For thicker or harder materials, a pilot hole roughly 80% of the thread diameter reduces driving torque and ensures the cleanest thread engagement.
