🔩 420‑Piece Self‑Drilling Tek Screw Kit – 410 Stainless Steel, #8 & #10, Hex‑Washer & Wafer Head

One kit, eighteen sizes, two head styles — this 420‑piece GooBetter assortment puts the right self‑drilling screw in your hand for any sheet metal, roofing, or framing job. Each screw features a hardened 410 stainless steel drill tip that bores through steel, aluminum, wood, and plastic without a pilot hole, then forms its own tight thread as it drives. The kit includes both hex‑washer heads for high‑torque socket driving and Phillips wafer heads for fast, flush installation, covering #8 and #10 diameters in lengths from 1/2″ to 2″. The 410 stainless construction provides superior hardness and good atmospheric corrosion resistance, making these screws ideal for metal roofing, HVAC ducts, steel studs, trailer decks, and mixed‑material assembly. Packed in a sturdy compartmented case with labeled sections, you can grab the exact size you need and get straight to work.

⚙️ Key Features – 420pc 410 Stainless Self‑Drilling Tek Screws

  • 410 stainless steel provides higher strength and hardness than 304, with solid atmospheric corrosion resistance indoors and outdoors
  • Self‑drilling tip eliminates the need for a pilot hole — one‑step fastening through sheet metal up to approx. 2 mm, wood, and plastic
  • Dual head styles: hex‑washer for high‑torque socket driving, and Phillips wafer (truss) for a low‑profile, flush finish
  • Covers #8 and #10 Imperial diameters in the most‑used lengths from 1/2″ to 2″ — 18 organized sizes in one kit
  • Magnetic and wear‑resistant — stays on the driver tip and holds tight under vibration
  • Supplied in a durable, transparent storage case with adjustable compartments and labeled sizes for quick selection
  • Ideal for metal roofing, steel framing, HVAC ductwork, trailer panels, wood‑to‑metal connections, and general shop repairs

❓ Frequently Asked Questions – 410 Stainless Self‑Drilling Screws

🔸 Do I need to pre‑drill a hole before using these?

No. The self‑drilling (Tek) tip is designed to penetrate sheet metal up to about 2 mm thick and wood composites without a pilot hole. For thicker or very hard materials, a pilot hole can reduce drive torque, but in most common applications, they are true one‑step fasteners.

🔸 How does 410 stainless steel compare to 304 for outdoor use?

410 stainless is harder and stronger than 304, which means the drill tip stays sharp longer. It offers good atmospheric corrosion resistance for roofing, siding, and general construction. For constant saltwater exposure, 316 is preferred, but for rain, humidity, and normal outdoor service, 410 holds up very well.

🔸 What tools do I need for a hex‑washer vs. a wafer head?

Hex‑washer heads use a standard 5/16″ (8 mm) socket or nut driver. Wafer heads have a Phillips recess — typically a #2 Phillips bit. The kit includes both head types so you can choose the best drive for the job.

🔸 Can these screws be used in wood or plastic?

Absolutely. The self‑drilling tip goes through the outer metal layer and then bites firmly into wood or plastic beneath. They are widely used for metal‑to‑wood connections like roofing to purlins, as well as plastic‑clad framing.
