Powerbuilt Universal Thread Repair Tool 11/16 to 1-1/2 in / 17-38 mm Metric — Adjustable Pitch, Aluminum Alloy

The Powerbuilt Universal Thread Repair Tool (643029ECE) restores stripped and damaged internal threads across a wide range of SAE and metric sizes quickly and with minimal fuss.

When a bolt won’t seat or a stud won’t engage, repairing the thread instead of replacing the entire component saves time, money, and waste. The Powerbuilt 11/16"–1-1/2" SAE / 17–38mm metric thread repair tool is a single, portable solution engineered to handle many common internal thread repairs in automotive, industrial, and household applications. Its adjustable pitch settings and durable aluminum-alloy construction make it a practical choice for mechanics and DIYers who need reliable results without carrying multiple tap kits.

Which thread sizes and standards does this tool cover?

This tool supports a broad span of thread diameters in both SAE and metric systems, eliminating the need for multiple size-specific tools. It’s intended for many standard fastener sizes you encounter on engines, machinery, and equipment housings.

• Covers SAE diameters from 11/16" up to 1-1/2"
• Handles metric diameters from 17mm up to 38mm
• Includes adjustable settings for matching thread diameter before repair
• Works with common thread forms used in automotive and industrial fasteners

How do fine and coarse pitch options improve repair accuracy?

Having separate fine and coarse pitch settings lets you match the original thread profile rather than forcing a close fit, which reduces the risk of cross-threading and ensures stronger reassembled joints. The tool’s pitch adjustment is intuitive, so you can dial in the correct engagement quickly.

• Selectable fine or coarse pitch to match original fastener
• Reduced risk of cross-threading with correct pitch alignment
• Better retention and torque transfer after repair
• Fast pitch changes without disassembling the whole tool

What makes the tool user friendly for pros and hobbyists?

Powerbuilt designed the tool with straightforward operation and clear instructions so users at any skill level can perform repairs with confidence. The ergonomic handling and visible adjustment indicators shorten the learning curve and speed up repetitive work.

• Simple setup and easy-to-read adjustment marks
• Clear instructions included for common repair steps
• Ergonomic grip for consistent control during cutting or chasing
• Compact form factor fits into crowded engine bays and gearboxes

How durable is the construction and what maintenance does it need?

Built from an aluminum alloy, the tool balances strength and weight so it stands up to workshop use while remaining easy to handle. Routine cleaning and light lubrication keep the moving parts functioning smoothly and extend service life.

• Aluminum-alloy body resists corrosion and reduces tool weight
• Robust internal components for repeatable repairs
• Simple cleaning and occasional lubrication recommended
• Store dry and protected to avoid debris buildup

Who is this for: The Powerbuilt Universal Thread Repair Tool is ideal for automotive technicians, small-engine mechanics, maintenance crews, and committed DIYers who want a single, versatile tool to restore internal threads without switching multiple taps. If you frequently encounter stripped bolt holes in engines, transmissions, housings, or structural assemblies and prefer a fast, durable repair method, this Powerbuilt tool is engineered to make those repairs faster and more reliable.
