ZerDans 163Pcs M4 Pan Head Machine Screws Kit, 6-30mm Black Carbon Steel — Open-Box, 15% Off

HIGH-HARDNESS CARBON STEEL BLACK：Upgrade your hardware! Unlike soft stainless screws that strip easily, Zerdans M4 screws are crafted from high-strength carbon steel. This ensures superior torque resistance and durability, effectively solving the "head rounding" issue common in generic kits during high-pressure fastening. SLEEK BLACK OXIDE FINISH：Stop compromising on aesthetics. While most competitors only offer silver, our professional black oxide coating provides a seamless, low-profile look. Perfect for black computer cases, dark furniture, audio equipment, and automotive interiors where silver hardware would look out of place. 10 ESSENTIAL SIZES (6MM-30MM)：Never be one screw short again. This 163pcs kit includes an extended range of lengths: M4 x 6/8/10/12/14/16/18/20/25/30mm. We’ve added more long-size screws (up to 30mm) to solve the pain point of missing deep-hole fasteners for thick cabinet panels or brackets. SNUG FIT PHILLIPS PAN HEAD：Designed for a flush and secure hold. The precision-engineered Phillips pan head allows for easy driving and a clean surface finish. These metric machine screws are ideal for home DIYers who need reliable fasteners for 3D printers, handles, and household appliance repairs. ORGANIZED & LABELED CASE：Say goodbye to messy toolboxes. Our kit comes in a heavy-duty transparent storage box with reinforced dividers. Each compartment is clearly labeled with size and quantity (M46 to M430), so you can identify the exact screw you need in seconds, even in the middle of a complex project.

Transform your repair projects from "amateur" to "professional" with the Zerdans Carbon Steel Black Screw Set.

Are you tired of silver screws clashing with your sleek black electronics or dark wood furniture? Or worse, have you ever had a screw head strip or snap right when you’re about to finish a project? Most standard stainless kits lack the hardness and the aesthetic appeal required for modern DIY tasks.

Why Choose Zerdans Black M4 Machine Screws?

Our screws are engineered for those who value both strength and style. By using high-density carbon steel with a premium black oxide treatment, we offer a fastener that is significantly harder than 304 stainless steel. This means the Phillips drive stays sharp and the threads bite deep without stripping, even in high-torque applications like PC building or cabinet hardware installation.

Comprehensive Range for Every Need

We analyzed common customer frustrations and found that most "standard" kits lack the longer screws needed for thick panels. The Zerdans 163-piece assortment fills that gap, providing 10 varied lengths from 6mm to 30mm. Whether you are mounting a new GPU, fixing a drawer slide, or maintaining your 3D printer, you’ll find the perfect fit right at your fingertips.
