Elizabeth U. ★★★★★

Fit the intermediate shaft in my headstock perfectly, no filing or fussing needed to get it seated. The 45 mm length feels solid and machined well for the price, and it's nice to have a spare on hand for when the old one finally wears out.

Emma T. ★★★★★

The headstock on my bench saw was wobbling until I swapped this key in on the intermediate shaft. The 4x45 mm dimensions matched perfectly, and it's held up through a dozen cuts without any play.

Penelope ★★★★★

The key slid into the intermediate shaft perfectly, and the 4x45 mm dimensions were exactly what I needed for my bench top machinery. It's a solid, precise fit that saved me from replacing the whole headstock.
