1-1/4-7 x 10" 六角頭螺絲 | 美國製造 | L9合金鋼黃鋅 | 部分螺紋 (6顆/包)

The partially threaded design made it much easier to start these bolts by hand before grabbing the socket. For assembling a heavy steel rack, the Grade L9 alloy steel felt rock-solid, and the yellow zinc finish looks clean and professional.

These bolts tightened up smoothly with a socket and held a heavy press frame solid with no slippage. The yellow zinc finish looks clean and the partial threads made alignment easy.

These L9 alloy steel cap screws are seriously beefy — the 1-1/4-7 thread is a solid step up from the standard stuff I usually work with. The partial threading made aligning them into a heavy frame much easier than fully threaded bolts would have.
