Kartek Off-Road 3/4" Shank to 5/8"-18 Thread Stepped 12-Point Flange Bolt 13-1/8" Long For Uprights

This twelve point flange bolt is made from 8740 alloy steel. 8740 is an aircraft grade material used in applications like cylinder head and rod bolts for its ability to resist being stretched, deformed or sheared under high stress loads. 8740 bolts are ideal for offroad racing suspension, spindle uprights, heims joints or uniballs.

Where the bolt drops down from 3/4" to 5/8" on the shank, there's a small tapered section that's roughly 1/8" long.

Dimensions:
• Length measured underneath the head 13-1/8" long
• 3/4" Smooth shank is 9-3/4" long
• 5/8" Smooth shank is 2-1/4" long
• 5/8-18 thread is 1" long
• Length measured underneath the head 13-1/8" long
• Uses 3/4" 12 point wrench

We use a NAS washer with our 3/4" twelve point bolts to make sure the head of the bolt sits flat against the spindle or misalignment.
