Gator Fasteners Thread Cleaning Chaser – M8 x 1.25 (TCCM8x1.25)

Clean up the smaller fastener threads before final assembly with the Gator Fasteners M8 x 1.25 Thread Cleaning Chaser. Corrosion, old thread locker, and carbon buildup in fastener holes throw off torque readings and can cause premature fastener failure — running this chaser through the threads first restores a clean, true thread path without removing base metal the way a tap does, so your fasteners torque to spec accurately.

• Thread size: M8 x 1.25
• Matches the secondary/accessory fastener threads on Gator Fasteners' 6.6L Duramax head stud kits (HSK66 and similar)
• Restores threads without cutting oversized like a tap
• A cheap insurance policy against a stripped or cross-threaded hole during engine assembly

Mfg Part #: TCCM8x1.25. Recommended any time you're installing head or main studs and accessory fasteners — run it through every hole before final assembly.
