Workshop hardware for heavy-duty bolt removal, built to transfer impact force and protect fasteners. Garage owners and DIY mechanics gain confidence when tackling seized crank and pulley bolts with a secure, impact-ready tool. Could CASOMAN Harmonic Balancer Socket be the reliable 24mm solution a busy workshop needs?

⚡ At a Glance
  • Torque Transfer: Upgraded 3X momentum power directs more impact energy into the bolt
  • Best for: Mechanics and DIY enthusiasts working on GM LS engines and heavy-duty pulleys
  • Not ideal for: Delicate fasteners or non-impact hand torque applications

Constructed from impact-grade chrome molybdenum steel with a 6-point profile. Compatible with 24mm GM LS engine damper bolts and finished with corrosion-resistant black phosphate.


Easier Removal of Stubborn Bolts – Thanks to Upgraded 3X Momentum Power

Momentum power multiplies impact energy transfer, directing more force into the bolt rather than the tool. Impact-grade chrome molybdenum steel endures repeated high-torque impacts.

Frees seized crankshaft and pulley bolts with fewer strikes, saving time and effort. Ideal when paired with a powerful impact wrench for workshop jobs.

Long-Lasting Durability – With Chrome Molybdenum Steel and Black Phosphate Finish

Chrome molybdenum construction meets impact-grade standards while a black phosphate coating adds corrosion resistance. Materials meet or exceed DIN performance standards.

Handles regular workshop wear and resists corrosion for extended service life. Keeps fit and function under demanding use.

Secure Grip That Prevents Rounding – With 6-Point Socket Design

A 6-point profile engages flat sides of hex bolts, reducing contact stress and limiting deformation. Snug geometry minimises slippage under high torque.

Maintains bolt head integrity during removal, lowering the risk of rounded corners and damaged fasteners. Makes bolt extraction safer and cleaner.

✨ The 4 Key Reasons for CASOMAN Harmonic Balancer Socket
  1. 3X momentum power – Reduces impact strikes needed to free stubborn crankshaft bolts.
  2. 6-point socket profile – Minimises bolt rounding under high torque, preserving bolt heads.
  3. Impact-grade CR-MO steel – Withstands repeated impacts for extended, reliable workshop use.
  4. 24mm compatibility for GM LS engines – Fits common damper bolts found on LS-family engines.
