1/4-20 x 1/2" 機械螺絲 | 平頭 十字槽 | 普通鋼 (1,000 顆/包)

Needed to mount a few pieces of plywood to a workbench, and these flat heads sit perfectly flush with the countersink. The threads are clean and consistent across all 1,000 screws.

Ordered these for a jig build and the 1/4-20 threads cut cleanly every time, zero stripped heads across the whole box. Plain steel is exactly what I needed for indoor use, and at a thousand pieces I won't be reordering for a while.

The flat heads sit perfectly flush in my jig, which my previous random-bin screws never did. For basic indoor shop jigs and fixtures, this bulk box is exactly what I needed.
