These are the top 30 main bolts that are largely used throughout the car. The most common place these are used is on the front end, starting with the hood hinges to the body, fenders and bumper brackets. Depending on your vehicle, they are also widely used on other body panels, under the hood, chassis and the interior.
DISCLAIMER: These are largely used on GM cars up to 1977 and full size trucks up to 1987. Most, but not all, converted to both metric and standard in 1978 and full metric in 1981. Please double check your application prior to your purchase to avoid unwanted return shipping charges.
