10-16x16-55 Zinc Yellow Wafer Head Self-drilling Screw

Product Overview
The Phillips Wafer Head Self-Drilling Screw (Model 10-16x16-55 Z/Y) is a self-drilling and self-tapping fastener designed for thin metal sheet connections. The product uses a #10 American thread specification (approx. 4.8mm diameter, 16 threads per inch fine thread design) and offers various lengths from 16mm to 55mm. The surface is treated with a yellow/color zinc (Z/Y) anti-rust coating, balancing durability with cost-effectiveness. It integrates drilling, tapping, and fastening into one, allowing direct penetration and fixation of metal plates without pre-drilling. It is an efficient and convenient general-purpose fastener for steel structures, light steel projects, and sheet metal installation.
