This 190‑piece GooBetter assortment puts five popular lengths — 1\/2″, 5\/8″, 3\/4″, 1″, and 1‑1\/4″ — all in one organized case. Each screw is made from 410 stainless steel, which is harder than standard 304, so the drill tip stays sharp when penetrating carbon steel up to about 3 mm. The wide Phillips wafer (truss) head spreads clamping force evenly and resists pull‑through in thin materials, while giving a flush, low‑profile finish. No pre‑drilling needed: the self‑drilling tip bores its own hole as you drive, making fastening quicker and cleaner. Whether you’re assembling trailer tracks, furniture, or metal brackets, this kit keeps your fasteners tidy and ready to go.\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 – 410 Stainless #8 Wafer Self‑Drilling Screws\u003c\/h2\u003e\n\u003cul class=\"hdiy-feature-list\"\u003e\n\u003cli\u003e190‑piece kit covering #8 diameter in five practical lengths: 1\/2″, 5\/8″, 3\/4″, 1″, and 1‑1\/4″ — all in a compartmented box\u003c\/li\u003e\n\u003cli\u003e410 stainless steel provides higher hardness and wear resistance than 304, ensuring the drill tip stays effective on steel sheet up to approx. 3 mm\u003c\/li\u003e\n\u003cli\u003eSelf‑drilling point eliminates the need for a pilot hole — one‑step fastening through sheet metal, plastic, and wood\u003c\/li\u003e\n\u003cli\u003eWafer head (Phillips truss) design offers a wide bearing surface to resist pull‑through and a low‑profile, flush appearance\u003c\/li\u003e\n\u003cli\u003ePhillips drive recess gives a secure, cam‑out‑resistant engagement with standard screwdrivers\u003c\/li\u003e\n\u003cli\u003eCorrosion‑resistant silver finish — suitable for indoor and mild outdoor environments\u003c\/li\u003e\n\u003cli\u003eIdeal for fastening sheet metal, rigid frames, furniture, trailer tracks, gutter guards, and general metal‑to‑metal or metal‑to‑wood connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c!-- Specifications Table --\u003e\n\u003cdiv class=\"hdiy-section\"\u003e\n\u003ch2 class=\"hdiy-heading\"\u003e📋 Kit Contents – 190pc #8 Wafer Self‑Drilling Screws\u003c\/h2\u003e\n\u003cdiv class=\"hdiy-table-wrapper\"\u003e\n\u003ctable class=\"hdiy-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003cth\u003eHead Style\u003c\/th\u003e\n\u003cth\u003eDrive\u003c\/th\u003e\n\u003cth\u003eMaterial \u0026amp; Finish\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 × 1\/2″\u003c\/td\u003e\n\u003ctd\u003e1\/2″\u003c\/td\u003e\n\u003ctd\u003e50 pcs\u003c\/td\u003e\n\u003ctd\u003ePhillips Wafer (Truss) Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless Steel, Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 × 5\/8″\u003c\/td\u003e\n\u003ctd\u003e5\/8″\u003c\/td\u003e\n\u003ctd\u003e50 pcs\u003c\/td\u003e\n\u003ctd\u003ePhillips Wafer (Truss) Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless Steel, Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 × 3\/4″\u003c\/td\u003e\n\u003ctd\u003e3\/4″\u003c\/td\u003e\n\u003ctd\u003e40 pcs\u003c\/td\u003e\n\u003ctd\u003ePhillips Wafer (Truss) Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless Steel, Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 × 1″\u003c\/td\u003e\n\u003ctd\u003e1″\u003c\/td\u003e\n\u003ctd\u003e30 pcs\u003c\/td\u003e\n\u003ctd\u003ePhillips Wafer (Truss) Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless Steel, Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 × 1‑1\/4″\u003c\/td\u003e\n\u003ctd\u003e1‑1\/4″\u003c\/td\u003e\n\u003ctd\u003e20 pcs\u003c\/td\u003e\n\u003ctd\u003ePhillips Wafer (Truss) Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless Steel, Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp class=\"hdiy-note\"\u003eTotal: 190 pieces.
