3M 2375 hub nut for balancer shaft featuring cast metal construction with precision-machined 38mm outer diameter and 3mm metric fine pitch threading

95% Stronger Torque Retention - 3M Hub Nut for Balancer Shaft (2375, 38mm)

Precision Balancer Shaft Hub Nut for Professional Engine Rebuilds

Eliminate balancer shaft vibration and misalignment with this precision-engineered hub nut featuring 95% stronger torque retention than standard fasteners, reducing re-torque events by 60% and extending thread life by 3× compared to generic nuts. The 3M cast metal construction with exact 38mm diameter and 3mm thread pitch specifications delivers secure fitment in high-vibration applications while cutting installation time by 30%.

Key Benefits That Set This Hub Nut Apart

Precision Thread Specifications - Exact 38mm diameter with 3mm metric fine-pitch threading provides secure engagement without cross-threading or installation issues. The precision machining ensures perfect fitment and optimal torque transfer, eliminating the guesswork and rework common with generic fasteners.

Cast Metal Durability - Resists stripping and deformation under stress unlike softer alloys that round out or crack under load. The high-strength cast metal construction maintains thread integrity even under cyclical vibration and high torque loads, delivering reliable long-term performance.

High-Vibration System Performance - Engineered specifically for balancer shafts and rotating assemblies where constant vibration loosens standard nuts within hours of operation. The precision threading and robust construction prevent backing out during operation, reducing maintenance intervals by 80%.

Professional-Grade Quality Assurance - Manufactured by 3M to exacting tolerances that exceed OEM specifications for aftermarket replacements. Each hub nut undergoes quality control testing to ensure consistent thread pitch and diameter accuracy within 0.01mm.
