most common fasteners used in mechanical assemblies are bolts, nuts and screws. Bolts usually (but not always) have hexa- gonal heads, as do nuts. Screws usually (again, but not always) have round heads and a slot or other recess to accommodate the appropriate driver tool. Nuts and bolts are most often tightened and loosened using wrenches, sockets and nut drivers; likewise, screws are driven tight or loosened using screwdrivers. There are myriad varieties of these tools and each have uses at which they excel. Let's explore these tools and what they're used for now.

month in Part 1 of Holding Fast we covered the various bolt types, the difference between bolts and screws, and we went into nuts and washers. This month our primer on fasteners continues, starting with the subject of coarseness. HOW FINE IS COARSE? Good question!

Varying the anle of the plane determines the cut or thread: increasing the angle pro- duces a coarse thread, while decreasing it re-
recap, in Part 1 we discussed the various bolt types, the difference between bolts and screws, then we went into nuts and washers; in Part 2 we covered fine vs. coarse threads, hardness, torque and head bolt markings. This month, in our final installment of our primer on fasteners, we cover other types of fasteners used frequently on Corvettes and in the garage. OTHER FASTENERS While threaded fasteners are the
