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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- Key Features – vertical list for SEO --\u003e\n\u003cdiv class=\"hdiy-section\"\u003e\n\u003ch2 class=\"hdiy-heading\"\u003e⚙️ Key Features – 370pc #8 Self‑Drilling Screws, Hex \u0026amp;
