Product Details

Moroso 38300 head bolt washers are precision-engineered fastener components designed for high-performance racing applications. Machined from 4130 chromemoly steel, these washers provide superior strength and durability compared to standard hardware.

Key Features:

  • Constructed from 4130 chromemoly steel for maximum strength
  • Heat-treated to optimal hardness for racing conditions
  • Parallel-ground surfaces ensure even stress distribution
  • Improved torque reading accuracy during assembly
  • Reusable design for multiple engine builds
  • Multi-purpose application: head bolts, main bearing caps, rocker arm stands

These professional-grade washers help prevent bolt head or cap surface damage while ensuring consistent clamping force. The parallel-ground finish eliminates variations that can lead to inaccurate torque specifications, making them essential components for precision engine assembly.
