5/8-11 X 2-1/4" 橢圓端內六角止付螺絲 | 合金鋼 (25個/包)

The hex socket drive is a lifesaver when you’re torquing these down in a tight spot—no stripped heads, just a solid grip. Oval point seated perfectly on the shaft, and the alloy steel feels tough enough to handle repeated adjustments. These are now my go-to for any heavy-duty set screw job.

These oval point screws grab onto shafts way better than the cup point ones I've used before. The hex drive made installation in a tight spot on my lathe much easier than I expected.

Finally, set screws that don't strip out after a couple of turns—the hex socket gives a solid grip even in cramped spots. These 5/8-11 x 2-1/4" oval points held a pulley in place on my lathe without any slippage, and the alloy steel feels tough enough for repeated adjustments.
