Gator Fasteners Thread Cleaning Chaser – M12 x 1.75 (TCCM12x1.75)

Clean up block and head threads before torquing new studs with the Gator Fasteners M12 x 1.75 Thread Cleaning Chaser. Corrosion, old thread locker, and carbon buildup in stud holes throw off torque readings and can cause premature stud 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 new studs torque to spec accurately.

• Thread size: M12 x 1.75 (coarse pitch)
• Matches the block-side thread on Gator Fasteners' 6.2L/6.5L diesel head stud kit (HSK6265)
• Restores threads without cutting oversized like a tap
• A cheap insurance policy against a stripped or cross-threaded hole on a head or main stud install

Mfg Part #: TCCM12x1.75. Recommended any time you're installing head or main studs — run it through every hole before final assembly.
