3/4-10 X 3-1/2" ヘビーヘックスキャップスクリュー | アメリカ製 | A307グレードBスチールプレーン | 部分ねじ切り (40個/パッケージ)

These threaded perfectly into an old press I was repairing, no binding or tight spots at all. The heavy hex head gives a good bite for the wrench, and the partial threading is just right for this kind of application.

Needed some heavy-duty bolts for a trailer hitch project, and these threaded perfectly into the frame without any wobble. The 3/4-10 size had just the right grip length for a solid hold.

These threads cut cleanly with no binding, and the hex head on these A307 grade B screws gave my wrench a solid grip for tightening down a press frame. The 3-1/2 inch length worked perfectly for the thick flange I was bolting together.
