🔩 370‑Piece #8 Self‑Drilling Screw Kit – Hex Washer & Truss Head, 410 Stainless with Black Oxide

Two head styles, five popular lengths, and the fast penetration of a self‑drilling tip — this 370‑piece GooBetter kit keeps you covered for sheet‑metal jobs, framing, and repairs. Each screw is made from 410 stainless steel, hardened for extra strength, and finished with a black oxide coating that adds a layer of corrosion resistance while providing a low‑profile, matte look. Choose the hex washer head when you need high torque with a socket driver, or the Phillips truss (round) head when you want a wide bearing surface and a flush finish. Both styles feature a drill‑bit tip that bores through steel, wood, and plastic without a pilot hole. The kit includes five exact #8 lengths — 1/2″, 5/8″, 3/4″, 1″, and 1‑1/4″ — all neatly organized in a sturdy plastic case, so you can grab what you need and get straight to work.

❓ Frequently Asked Questions – 410 Stainless Self‑Drilling Screws

🔸 Do I need a pilot hole with these self‑drilling screws?

No. The drill‑shaped tip will penetrate sheet metal up to about 2 mm thick, as well as wood and plastic, without a pilot hole. For thicker or harder materials, you can always use a small pilot hole to reduce drive torque, but in typical applications, they are one‑step fasteners.

🔸 Will the black oxide finish rust?

The black oxide coating provides an additional layer of corrosion protection over the already rust‑resistant 410 stainless steel. It will hold up well in indoor and mild outdoor conditions. For constant saltwater exposure, consider 304 or 316 stainless, but for general use, the black oxide 410 stainless combination is very durable.

🔸 When should I use the hex head vs. the truss head?

The hex washer head is driven with a 5/16″ socket and allows more torque without cam‑out – ideal for heavy sheet‑metal and framing work. The truss (round) head has a wider bearing surface to resist pull‑through and uses a standard #2 Phillips screwdriver, making it great for finish work, thin panels, and applications where the fastener should sit flatter.

🔸 Are these screws magnetic?

Yes, 410 stainless is magnetic, which can be helpful when using a magnetic‑tip driver or picking up dropped screws. This is normal for this grade and does not affect corrosion resistance.
