M20 X 35mm 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 合金鋼 (10個/包)

Installed these as pivot axles on a custom jig and the fit was dead-on. The hex socket drive made torquing them down straightforward without any stripped heads.

I used these as pivot pins for a heavy-duty jig, and the hex socket drive made installation effortless with a simple Allen key. The alloy steel feels tough enough to handle repeated loads without any flex.

The precision-ground shoulder on these M20 screws made for a much smoother pivot action than the standard bolts I've used before. The hex socket drive seated perfectly with my wrench, and the steel feels solid enough for heavy use. A great choice for custom axle setups.
