The RIDGID TOOLS 37620 is a 00-RB series hand threader die head designed to cut unified national coarse (UNC) right-hand external threads on 3/8-inch bolt stock. The die is machined from alloy steel for hardness and wear resistance during repeated threading operations. This die head mounts into the 00-RB manual bolt threader frame and is a direct replacement or supplemental die for shops and field crews that need consistent thread form without power equipment. Plumbers, pipefitters, and general tradespeople use this type of die head when threading fasteners or all-thread rod by hand on the job.
The 37620 die head is used in light industrial, commercial, and residential applications where a manual bolt threader is the preferred or required tool. It is suited for work on 3/8-inch fasteners and all-thread stock requiring a standard UNC thread profile. The 00-RB series is a compact, hand-operated platform commonly found in plumbing and mechanical contractor tool inventories.
Designed for use with the RIDGID 00-RB manual bolt threader.
Installation of the die head into the 00-RB threader frame should be performed per the tool manufacturer's instructions before beginning any threading operation. Ensure the die head is fully seated and secured in the frame before applying cutting pressure to the workpiece. Use appropriate thread-cutting oil to extend die life and produce clean thread form. Inspect die teeth for wear or damage before each use and replace if thread quality degrades.
