About This

• 【Two-Piece Chicago Screw Set – Stud & Nut Design】This set includes two separate components: Phillips flat-head screws (M3 x 5mm) and mushroom-head nuts (8mm diameter head). The material is securely sandwiched between the screw head and the decorative nut – a classic "stud & post" fastening system widely used in leathercraft, garment making, and thin-material DIY projects.
• 【Zinc Alloy Construction with Anti-Corrosion Coating】Made from durable zinc alloy and protected with a gold electroplated layer, these screw studs offer good strength, rust resistance, and scratch protection. They withstand daily handling, moisture, and friction without fading or tarnishing – ensuring long-lasting beauty and reliability for both wearable accessories and crafted keepsakes.
• 【Precision Sized for 0.5–2mm Thin Materials】With a 5mm screw length (M3 thread), this set is specifically engineered for single-layer or thin double-layer materials ranging from 0.5mm to 2mm in total thickness – perfect for lightweight garment leather, nylon straps, key fobs, and decorative trims. The screw sits flush against the back surface for a clean, comfortable finish.
• 【Removable & Reusable – Tool-Free Adjustment】Unlike permanent rivets that require hammering, these screw studs are fully detachable and reusable. Simply use a Phillips screwdriver to tighten or loosen – ideal for applications where you may need to disassemble, adjust tension, or replace worn materials without damaging the workpiece.
• 【50-Piece Value Set – Enough for Multiple Projects】Each pack includes 50 screw posts and 50 matching nuts – ample quantity for hobbyists, small studios, or quick home repairs. Stock up once and have reliable hardware on hand for all your leathercraft needs at a budget-friendly cost.
