Converter Bolt 7/16-20x 1.250

The Converter Bolt 7/16-20x 1.250 from Mr. Gasket is a precision fastener kit engineered for high-performance torque converter assembly and retention. Designed specifically for GM 10-inch race converters, this three-piece bolt set addresses a critical need in automatic transmission builds where reliable fastening directly impacts drivetrain integrity and longevity. Whether you're building a competition vehicle, restoring a classic with modern powertrain upgrades, or servicing heavy-duty transmissions, this converter bolt kit delivers the specification-critical fastening solution required for proper assembly torque and load retention.

Each bolt in this converter bolt kit features a 7/16-20 thread pitch with a 1.25-inch length, hex head design, and black oxide finish for corrosion resistance and consistent friction characteristics during torque application. The black oxide coating provides superior corrosion protection in high-temperature transmission environments while maintaining reliable surface finish for accurate torque wrench calibration. Constructed from hardened steel, these fasteners are engineered to withstand the cyclical shear and tensile loads inherent to converter bolt applications. The included hex nuts enable secure locking, preventing vibration-induced loosening during extended operation—a critical consideration in racing and performance applications where converter slip or bolt failure can result in catastrophic transmission damage.

Technicians, transmission builders, and performance enthusiasts working with GM 10-inch race converters will find this bolt set essential for proper installation and reassembly. The three-piece configuration matches OEM converter bolt count requirements, ensuring complete assembly without supplementary fasteners. Installation is straightforward: apply converter bolts to torque converter mounting surface, secure with included hex nuts, and torque to manufacturer specification (typically 30–35 ft-lbs for converter bolts). This kit is ideal for transmission builds, converter replacement, or repair of existing GM automatic transmissions where fastener degradation or loss has compromised assembly integrity.
