1/4"-20 x 5/8" (25 PCS) Button Head Socket Cap Screws, 304 Stainless Steel (18-8), Fully Threaded, Inch Thread - Hex Allen Drive - for Furniture, DIY, 3D Printing, Industrial & Tools

Brand: HirtuOtter
  • Durable 304 Stainless Steel Construction: Crafted from corrosion-resistant 18-8 stainless steel, these screws are suitable for both indoor and outdoor applications. Please note that the magnetic properties of 304 steel always show weak magnetic properties due to the structure transformation reasons. This will not affect its high rust resistance, feel confident choosing this.
  • Button Head Design for Enhanced Durability: The rounded Button Head provides a larger surface area for secure tightening and better wear resistance. This design is ideal for applications where a smooth, non-protruding finish is needed, offering both strength and aesthetic appeal.
  • Eco-Friendly and Reusable Packaging: Each set comes in a sturdy, reusable plastic box and individual plastic bags. This protects screws from loss, keeps your workspace organized, and supports sustainable practices.
  • Built for Precision Applications: Widely used in assembling aluminum frames for 3D printers, securing motorcycle fairings, mounting electronic enclosures, or repairing furniture. Reviewed positively for excellent threading and clean finishes in both hobbyist and industrial settings.
  • 24/7 Customer Support That Listens: HirtuOtter is a customer-focused brand. Our support team is available 24/7 to assist you before and after purchase, helping make every project “Better and Easier”.
