Natalie ★★★★★

This SC4-281 pin slid perfectly into the alignment jig I'm rebuilding, and the 4x40mm dimensions were spot on. The parallel sides made for a much snugger fit than the tapered dowels I've tried before.

George D. ★★★★★

Needed a 4x40mm pin for a Sieg lathe cross-slide rebuild, and this one fit the SC4-281 part number perfectly. The surface finish is smooth and the parallel tolerance seems spot-on for a snug fit without any binding.

Benjamin ★★★★★

Exactly 4mm by 40mm, so it dropped right into the SC4 assembly without any filing or forcing. The parallel sides are clean and true, and it stayed put once pressed in. Just what the parts diagram calls for.
