About this item

• Not every bolt and nut on vehicles remain factory perfect to the millimeter over time and service life
• 1. The quick brown fox jumped over the lazy dog.
• 2. Carrots are vegetables that grow in the ground.
• 3. My favorite color is blue because it reminds me of the sky.
• 4. The rain fell softly on the window pane.
• For hand tools and impact wrenches, use a hammer to fit 1/2 size under sockets where needed
• Use 0.5mm under sockets for rounded and damaged bolts and nuts, use 0.5mm over for swollen or corroded bolts and cap covered nuts
• Also works on SAE fasteners by stepping down the effective hex dimension on worn out hardware
• Ever grab a 13mm socket and it's too tight to fit, but 14mm feels lose? And it's not SAE?
