Lever-Cap Screw – 6.5 mm–20 Thread – Stainless Steel • Big-Head Grip

The lever-cap screw is one of the most-abused, most-missing parts on vintage planes. We brought it back so you can put your tool back to work instead of hunting for hardware that doesn’t exist.

This is the hard-to-find 6.5 mm–20 thread lever-cap screw, made in stainless steel and designed with a large grip head for confident tensioning. It’s shop-tested, easy to handle, and locks down cleanly whether you’re running an original Stanley or one of our Woodyah reproduction caps.

Why Woodworkers Choose This Screw

• ✅ Proper Thread: Cut to the correct 6.5 mm–20 spec found on Stanley 78 rabbet planes, 40 and 40 1/2 scrub plane lever caps, and others. (please let me know I'll add them.)
• ✅ Stainless Steel: Built to resist rust, shop grime, and decades of use.
• ✅ Big Head: Easy to grip, easy to turn, less chance of chewing the slot.
• ✅ New + Antique Compatible: Works with Woodyah lever caps and many original Stanley caps.
• ✅ Shop-Tested: Holds tight for consistent, chatter-free cuts.

This is the screw that should have come with your plane. No guesswork, no mismatched hardware, just the right thread and the right head.

“Proper threads, perfect head — exactly what these tools needed.”
