1/4-20 x 1-1/8" 六角頭螺絲 | 8級鋼 黃鋅鍍層 | 全螺紋 (2000 / 包)

I needed a bulk pack for a frame jig I’m building, and these fully threaded Grade 8 screws are tough enough to handle heavy torque without stripping. The yellow zinc finish is a nice bonus for corrosion resistance too.

The hex heads on these bolts grab the socket perfectly without any wobble, which saves time on a big assembly job. The yellow zinc coating looks consistent across all 2,000 pieces, so I’m confident they’ll hold up in the shop. For the price per fastener, this pack is a steal when you’re doing heavy

I needed a serious batch of fasteners for rebuilding a heavy-duty jig, and these hex heads bit in perfectly with my socket driver. The threads are clean and uniform across the entire length, so every one seated without a single gall.
