Reed Manufacturing B-13 632UNC Thread Rolling Die

The Reed Manufacturing B-13 6-32 UNC thread rolling die is an external-thread forming die designed for use with Reed’s cross-slide thread rolling attachments to form precise 6-32 UNC threads on small-diameter stock. The die is designated B-13 and is configured to operate with Reed‑Rico thread rolling attachments, which consist of a head and an adapter as a two-unit system. It is mounted on the cross slide of automatic screw machines and lathes, where it engages with the rolling dies in the attachment to form threads by plastic deformation rather than cutting. When paired with the corresponding Reed rolling head and adapter, the B‑13 die yields consistent 6-32 UNC thread forms, contributing to repeatable dimensions and fit for production parts requiring standard UNC threading. This configuration makes it a specialized option for production threading operations that rely on stable tooling and integrated roll‑forming workflows within Reed’s tooling ecosystem.
