These Phillips truss head self-tapping screws are crafted from genuine A2\/304 stainless steel and hardened, then treated with a high‑temperature oxidation process that turns the surface a deep, matte black. Unlike painted or coated screws, the black layer is chemically bonded to the stainless substrate: it won’t chip, peel, or leave exposed steel that rusts. The oversized truss head spreads clamping force evenly, preventing pull‑through in thin sheet metal, plastic panels, wood, and fiberglass. Sharp self‑tapping threads cut their own path as you drive — no tap, no pilot hole in most materials. Available from M2.9 to M4.2, this series covers electronics enclosures, automotive interior panels, outdoor fixtures, marine hardware, and any project where strength, style, and weather resistance are non‑negotiable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- Key Features – no emoji on list items --\u003e\n\u003cdiv class=\"gbs-section\"\u003e\n\u003ch2 class=\"gbs-heading\"\u003e⚙️ Key Features – Black 304 Stainless Truss Head Self-Tapping Screws\u003c\/h2\u003e\n\u003cul class=\"gbs-feature-list\"\u003e\n\u003cli\u003eGenuine 304 (A2) stainless steel provides excellent corrosion resistance in wet, humid, and coastal environments — won’t red‑rust\u003c\/li\u003e\n\u003cli\u003eHigh‑temperature black oxidation creates a matte black finish that’s integral to the metal, not a paint or plating\u003c\/li\u003e\n\u003cli\u003eA wide truss head distributes clamping load and resists pull‑through in thin or soft materials\u003c\/li\u003e\n\u003cli\u003ePhillips drive recess centers the bit for stable torque and reduced cam‑out\u003c\/li\u003e\n\u003cli\u003eSelf‑tapping thread cuts cleanly into sheet metal, wood, plastics, and composites — no pre‑tap required\u003c\/li\u003e\n\u003cli\u003eCovers M2.9, M3.5, M3.9, and M4.2 diameters, the most common sizes for light‑ to medium‑duty assembly\u003c\/li\u003e\n\u003cli\u003eIdeal for electronics, auto trim, marine equipment, outdoor fixtures, and all‑weather DIY builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c!-- Specifications Table --\u003e\n\u003cdiv class=\"gbs-section\"\u003e\n\u003ch2 class=\"gbs-heading\"\u003e📋 Technical Specifications – Black 304 Truss Head Self-Tappingg Screws\u003c\/h2\u003e\n\u003cdiv class=\"gbs-table-wrapper\"\u003e\n\u003ctable class=\"gbs-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eDiameter\u003c\/th\u003e\n\u003cth\u003eThread Size\u003c\/th\u003e\n\u003cth\u003eTypical Length Range (mm)*\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\u003eM2.9\u003c\/td\u003e\n\u003ctd\u003e2.9 mm\u003c\/td\u003e\n\u003ctd\u003e6 – 25\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e304 Stainless Steel, High‑Temp Black Oxide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM3.5\u003c\/td\u003e\n\u003ctd\u003e3.5 mm\u003c\/td\u003e\n\u003ctd\u003e8 – 40\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e304 Stainless Steel, High‑Temp Black Oxide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM3.9\u003c\/td\u003e\n\u003ctd\u003e3.9 mm\u003c\/td\u003e\n\u003ctd\u003e10 – 50\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e304 Stainless Steel, High‑Temp Black Oxide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM4.2\u003c\/td\u003e\n\u003ctd\u003e4.2 mm\u003c\/td\u003e\n\u003ctd\u003e12 – 60\u003c\/td\u003e\n\u003ctd\u003eTruss Head\u003c\/td\u003e\n\u003ctd\u003ePhillips\u003c\/td\u003e\n\u003ctd\u003e304 Stainless Steel, High‑Temp Black Oxide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp class=\"gbs-note\"\u003e* Lengths are thread length only, excluding head.

It forms directly on the stainless steel and won’t chip or peel. Because the base material is genuine 304 stainless, it resists red rust even in outdoor or marine environments — just like natural silver 304, only darker.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003e🔸 How does a truss head compare to a pan head?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA truss head has a noticeably wider and flatter bearing surface than a pan head. This spreads the clamping force over a larger area, which prevents the head from pulling through thin sheet metal, plastic, or soft wood. It gives you a stronger clamp without needing a separate washer.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003e🔸 Can I use these in wood as well as metal?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eYes. The sharp self‑tapping thread engages both wood and sheet metal equally well. For hardwoods like oak or maple, we recommend a small pilot hole (about 80% of the screw diameter) to make driving easier and protect the thread.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003e🔸 Do I need a pilot hole in sheet metal?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eIn thin sheet metal up to about 1.2 mm, you can usually drive them straight in. For thicker steel or harder materials, a pilot hole will reduce drive torque and ensure the cleanest thread engagement.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003e🔸 Are the screws magnetic?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003e304 stainless is generally non‑magnetic in its annealed state.
