| Cap Screws vs. Bolts |
|||||||||||||||||||||||||||
| The hallmark of many quality aftermarket rods is the use of a cap screw fastener system rather than the traditional OE- style nut and bolt. Though the best aftermarket nut and bolt may rival the best aftermarket cap screw in tensile strength, the need to machine spot- face into the shoulders of the rod (to locate the bolt head) is a weak point rods can live without. When the cap screws are used, the shoulders of the rod can be formed to maximize strength. |
