3/8-24 X 1" 內六角螺絲 | 內六角驅動 | 合金鋼 (160 顆/包)

Installed these on a fixturing jig this morning and the hex drive seated perfectly without any wobble. The alloy steel feels solid and they threaded cleanly into blind holes with no galling.

Had to replace a worn batch on an older fixture, and these alloy steel screws threaded in perfectly without any binding. The hex socket drive made tightening a lot easier compared to standard hex heads. Set of 160 leaves me plenty of spares for future repairs.

Needed a batch for a custom jig I was building, and the threads on these were clean and engaged smoothly right from the pack—no binding or burrs. They're stout enough for heavy clamping loads without any worry.
