Description

Tillotson Side Cover Bolts – M8x1.25x32mm | Grade 10.9 High-Strength Bolts


These Tillotson Side Cover Bolts are the direct OEM replacements for many Honda GX200-style and clone engines. Engineered to meet automotive-grade performance standards, they provide superior clamping force and durability—ideal for stock and high-performance builds alike.


Each bolt is precision-machined to M8x1.25 x 32mm dimensions and made from Grade 10.9 steel, delivering 150,000 psi tensile strength. That’s equivalent to Grade 8 in SAE specs—far superior to the lower-grade fasteners often found in standard engine assemblies.


Key Features:

  • OEM Fitment: Designed as the stock side cover bolt for Tillotson and many clone engines.
  • Grade 10.9 Steel: Offers high tensile strength and torque tolerance for racing and modified engines.
  • Better Than Grade 5: Stronger than commonly used Grade 5 or Grade 2 bolts—ideal for improved side cover clamping and longevity.
  • Precision Dimensions: M8 x 1.25 thread pitch, 32mm length.
  • Easy Installation: Uses a standard 10mm wrench or socket.
  • Torque Spec: 26 ft/lbs (312 in/lbs) recommended.


Fitment:

Compatible with the following small engines:

  • Honda GX200 / Clone 196cc
  • Tillotson 196cc – 268cc
  • Wildcat 223 / 240
  • Ducar 196 / 212 / 224
  • Predator 212 (Hemi & Non-Hemi)
  • Predator 224 Non-Hemi
  • Ghost 212


Pro Tip:

For high-performance builds, pair with a billet side cover and consider using thread locker for added vibration resistance on endurance engines.
