Frequently asked questions

Is 9mm the same as a standard drill bit size?
9mm (0.354 inches) is very close to common drill bit sizes. It's slightly larger than a 5/16 inch drill bit (0.3125 inches) and slightly smaller than 3/8 inch (0.375 inches). For most practical drilling applications, a 3/8 inch bit would be the nearest standard equivalent.
Will a 9mm bolt fit through a hole meant for 3/8 inch fasteners?
No, a 9mm bolt (0.354 inches) is too small to fit securely in a hole sized for 3/8 inch (0.375 inches) fasteners. The bolt would have excessive play and wouldn't hold properly. You should use appropriately sized bolts for your hole diameter.
