3/8-16 × 1-1/2" 機械螺絲 | 平頭82° 十字驅動 | 鋼鋅鍍 (200/包)

I used these to attach a metal bracket to a steel frame and the zinc coating has held up well so far. The flat 82° head sits flush without sticking out, which was exactly what I needed for a clean finish.

The threads were crisp and clean on every single screw, so they drove into predrilled holes without any binding or stripping. I used a dozen to secure a steel bracket to a frame, and the flat 82° heads sat perfectly flush. Pack of 200 is more than I needed, but nice to have extras on hand.

Packaged well and the 82° flat heads sit perfectly flush in my metal enclosures. The zinc coating looks clean and should resist corrosion just fine. Used a dozen so far and every one threaded smoothly without any binding.
