Hex Bolt vs Hex Set Screw
A Hex Bolt is the term uséd for a partially threaded fastener, with a hexagon head; designed to be uséd with a nut and washer. A Hex Set (Screw Bolt) is the same, except it is fully threaded. A screw screws into something, a bolt joins several things together from both sides of materials joined. A screw is fully threaded from underneath the head and a bolt is partially threaded (has a part-plain shank/ shoulder).
UNIFIED THREAD STANDARDS
Thread standards agreed upon by standard bodies of Canada, the United Kingdom, and the United States.
Unified National (UN) thread form with a rounded root contour, applies only to external threads. (The UN thread form has a flat, or optionally, a rounded root contour.) The majority of fasteners with a Unified thread form (UNC, UNF) have a rounded root contour i.e. are UNR threads.
Unified National Fine (UNF) is a thread form with a 60 degree flank angle rounded roots and flat crests. For a given diameter it has a smaller thread pitch than an equivalent diameter UNC thread.
