XunLiu 1/4-20X1-3/4 Button Head Socket Cap Screws Pack of 50

• 【PREMIUM 304 STAINLESS STEEL 18-8】LIFETIME CORROSION RESISTANCE — NO COATING NEEDED — Engineered with 18-8 composition (30% nickel, 8–10% chromium), these screws deliver decades of structural and aesthetic integrity in saltwater, marine, high-humidity, and industrial environments. Outperforms zinc-plated alternatives with zero maintenance required.
• 【1-3/4" MAXIMUM LENGTH IN SERIES】DEEPEST THREAD ENGAGEMENT & STRONGEST HOLDING POWER — The longest variant in this screw family (44.45mm / 1-3/4"), providing maximum thread engagement depth for superior clamping force. Ideal for thick wood substrates (≥1.5"), stacked metal plates, heavy machinery bases, and high-vibration or high-tensile-load applications where shorter screws simply won't hold.
• 【LOW-PROFILE BUTTON HEAD DESIGN】FLUSH FIT WITH EVEN PRESSURE DISTRIBUTION — Precision-engineered rounded head sits flush against fastened surfaces with zero protrusion, distributing contact pressure evenly to minimize surface wear and scratching. Perfect for visible, aesthetic-sensitive installations including furniture panels, equipment housings, and vehicle trim components.
• 【INTERNAL HEX SOCKET DRIVE】CAM-OUT RESISTANT — HAND TOOL & POWER DRIVER READY — Standard 1/4" internal hex drive accepts the included Allen wrench for precise torque control or the power driver bit for rapid installation. Eliminates stripping and cam-out, and enables secure fastening in confined spaces with limited side clearance.
• 【50-PIECE COMPLETE KIT — READY TO USE INSTANTLY】UNIVERSAL MULTI-MATERIAL COMPATIBILITY — Includes 50 precision button head screws + standard Allen wrench + hex socket power driver bit. Industry-standard 1/4-20 UNC threading works across metal, wood, plastic, and composite materials for motorcycle frames, thick lumber furniture, industrial equipment, solar panel structures, and more — no additional tool purchases required.
