Bolt Depot - How Fastener Measurements are Notated
Drive Type. Drive type describes the type of tool used to install the fastener. Common examples are phillips, slotted, and square drives. Some fasteners, such as carriage bolts, do not have a drive and therefore no drive type is specified. In certain other cases, Measuring Fastener Length · Measuring Fastener Diameter · Thread Pitch and Thread Count[PDF]

Axis of Thread Major diameter Mean (pitch) (d or c d ) diameter ( d or d )p m. Unified and ISO Thread Geometry Pitch (p) – The distance between adjacent thread forms measured parallel to the thread axis. Lead (L) – The distance the nut moves parallel to the screw axis when the nut is given one turn.[PDF]

in which a screw is mated into a matching female thread in a workpiece (therefore only requiring one tool to tighten or loosen). As seen in figure 1, studs are a hybrid between a bolt and a screw, since one end of the stud functions as a screw while the other functions as a bolt.
The Easiest Way to Read a Screw Thread Callout - wikiHow

B1.7 - 2006 Screw Threads: Nomenclature, Definitions, and
The purpose of this Standard is to establish a uniform practice for standard screw threads with regard to the following: (a) screw thread nomenclature; (b) letter symbols for designating features of a screw thread for use on drawings, in tables that set forth dimensional standards, in other records, and for expressing mathematical relationship.
Bolt Depot - How to Identify Nuts, Bolts, and Screws
In other categories such as lag bolts there is either only one drive type or the drive type is implied to be of a standard type. For help identifying different fastener drive types see our Fastener Type Chart. Ex. Philips, Slotted, Allen (a.k.a. Socket), Frearson (similar to Philips), etc.
Fastener Standards - ASTM International
