If you're swapping or upgrading your torque converter, these JEGS bolts are exactly what you need to get the job done right. Specifically designed for TH350 and Powerglide converters, this kit includes three 3/8\\\-24 x 5/8\\\ Grade 8 bolts with matching Grade 8 hex nuts - the good stuff that won't let you down. That Grade 8 rating means they're tough enough to handle the vibration and stress that converters deal with every day. The hex head design makes tightening to proper torque specs a breeze with your wrench or socket. Made from solid steel, these aren't some cheap hardware store alternatives that might strip or break when you need them most. Seriously, this is one of those must-have items when you're working on your transmission - trying to reuse old bolts or using the wrong ones is just asking for trouble down the road. The package has everything you need for a solid installation that'll stay put. Whether you're building a street machine or a drag strip warrior, having the right hardware matters, and these JEGS bolts deliver that peace of mind knowing your converter is securely mounted exactly how it should be.
