Customer Reviews (4.6 / 5 · 5 reviews)

Eli ★★★★★

Threads cut clean and true against the original compound, and the fit was spot-on with zero slop during my test runs. Took maybe ten minutes to swap out, and the adjustment now feels buttery compared to the worn one it replaced.

Lily Z. ★★★★★

The 20 TPI thread engagement feels noticeably crisper than the original that came on my Sieg machine—adjustments are much more repeatable now. Worth the swap for anyone dealing with compound slide slop.

Mia J. ★★★★★

The 20 TPI threads cut perfectly onto my compound slide, and the fit is snug with zero backlash play. It’s a direct bolt-on replacement, so I didn’t have to shim or re-drill anything. Exactly what my Sieg needed to get back to precise turning.
