Why woodworkers like this screw

Proper Thread: Made to the 6.5 mm–20 spec used on many vintage lever caps.
Stainless Steel: Resists rust in real-shop conditions; threads stay crisp.
Large Head, Big Slot: Positive grip and torque without chewing the slot.
New + Antique Compatible: Works with Woodyah lever caps and many original caps that were built for this thread.
Shop-Tested: Locks down cleanly for a consistent, chatter-free scrape or cut.

Compatibility & Fit

Use case: Lever-cap clamping/tension on scrapers and planes designed for 6.5 mm–20.

Works with: Woodyah new lever caps; many antiques that originally shipped with 6.5 mm–20 hardware.

Stanley 82 owners: This size is commonly used; verify your original thread before ordering.

Quick Fit Check

Measure shank Ø: Use calipers on your original screw (or the cap’s threaded boss). You’re looking for ~6.5 mm OD.
Thread pitch: 20 TPI equivalent for this diameter. If a 1/4-20 feels loose or binds early, your tool likely needs 6.5 mm–20.
Test by hand: The screw should start smoothly, seat flush, and clamp without wobble.

Tip: If your current screw chews the slot, won’t hold tension, or feels “gritty,” replace it — threads or plating may be worn.

Install & Use Notes

Start threading by hand; if you feel resistance in the first 1–2 turns, re-verify thread spec.

Seat the lever cap, then tighten until the tool cuts cleanly without chatter.

If your cap or boss has damage, chase the threads or replace the boss for best results.

FAQ

Will this fit my antique?
If your original hardware is 6.5 mm–20, yes. Measure with calipers or test with a known 6.5 mm nut. If a 1/4-20 feels sloppy or binds, your tool likely needs 6.5 mm–20.

Is the head truly easier to grip?
Yes — we spec a larger head and deeper slot for positive torque and less slot damage over time.

Will it resist rust?
It’s stainless steel, chosen for shop environments where moisture and fingerprints are common.
