M3 Carbon Steel Nickel Plated Pan Head Combination Screws with Flat & Spring Washers for Electronics & Assembly

These carbon steel nickel-plated round (pan) head three-combination screws are engineered for industrial assembly, electronics, machinery, home repair, and DIY projects. Crafted from high-quality carbon steel with a smooth nickel plating, they deliver exceptional durability, corrosion resistance, and a sleek finish—perfect for both professional and everyday fastening needs.

 

Featuring a 3-piece combination design (screw + flat washer + elastic/spring washer), these cross (Phillips) pan head bolts eliminate the need for separate washers, saving time during installation. The flat washer distributes pressure evenly to prevent surface damage, while the elastic washer provides strong anti-loosening performance, ensuring a secure hold even in vibration-prone environments.

 

Available in size M3—a widely used standard size—these combination screws are versatile for a range of applications: electronic device assembly, machinery maintenance, furniture installation, small appliance repair, and DIY crafting. The cross (Phillips) slot allows for easy, stable driving with standard tools, while the pan head offers a low-profile, clean look that works well for both visible and hidden fastening.

 

Designed for professionals, contractors, and DIY enthusiasts, these nickel-plated carbon steel combination screws balance strength and convenience. The nickel plating enhances corrosion resistance, making them suitable for indoor and light outdoor use, while the integrated washers ensure reliable performance in every application—from industrial production to home repairs.
