The wide, flat‑bottom truss head spreads clamp force to stop pull‑through in thin sheet metal, plastic, and plywood, while the sharp, hardened thread cuts its own tight path — no pilot hole in most materials. Made from 410 stainless steel with a black oxide coating, each screw combines higher strength than standard 304 with a dark, non‑reflective finish that blends into shadowed assemblies. The kit covers five practical lengths from 1\/2″ to 1‑1\/4″, putting a professional‑grade fastener within arm’s reach for HVAC ducting, auto panels, trailer trim, furniture, and general workshop use.\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 – 190pc Black Truss Self‑Tapping Screws\u003c\/h2\u003e\n\u003cul class=\"hdiy-feature-list\"\u003e\n\u003cli\u003e410 stainless steel with black oxide finish – harder than 304, resists corrosion indoors and in mild outdoor environments\u003c\/li\u003e\n\u003cli\u003eSelf‑tapping thread eliminates pre‑drilling in thin metal, wood, and plastic – one‑step fastening saves time\u003c\/li\u003e\n\u003cli\u003eWide truss head distributes load to prevent pull‑through and gives a clean, finished look\u003c\/li\u003e\n\u003cli\u003ePhillips recess centers the bit for smooth, cam‑out‑resistant driving\u003c\/li\u003e\n\u003cli\u003eImperial #8 diameter in five lengths: 1\/2″, 5\/8″, 3\/4″, 1″, 1‑1\/4″ — organized quantities for everyday use\u003c\/li\u003e\n\u003cli\u003e190‑piece kit packed in a reusable case keeps sizes separated and easy to find\u003c\/li\u003e\n\u003cli\u003eIdeal for sheet metal, rigid frames, furniture, gutter guards, trailer track, and mixed‑material assemblies\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 – #8 Black Truss Head Self‑Tapping 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\u003eDiameter\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\u003cth\u003eQty\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 x 1\/2″\u003c\/td\u003e\n\u003ctd\u003e#8 (~4.2 mm)\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless, Black Oxide\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 x 5\/8″\u003c\/td\u003e\n\u003ctd\u003e#8 (~4.2 mm)\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless, Black Oxide\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 x 3\/4″\u003c\/td\u003e\n\u003ctd\u003e#8 (~4.2 mm)\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless, Black Oxide\u003c\/td\u003e\n\u003ctd\u003e40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 x 1″\u003c\/td\u003e\n\u003ctd\u003e#8 (~4.2 mm)\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless, Black Oxide\u003c\/td\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e#8 x 1‑1\/4″\u003c\/td\u003e\n\u003ctd\u003e#8 (~4.2 mm)\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e410 Stainless, Black Oxide\u003c\/td\u003e\n\u003ctd\u003e20\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. #8 thread diameter approx. 4.2 mm.
