High Tensile, UNC Hex Bolts and Hex Sets.

UNC and UNF high tensile standard is marked with an, '5'. This is comparable with Metric, High Tensile - 8.8.

Hex Bolt vs Hex Set Screw

A Hex Bolt is the term used for a partially threaded fastener, with a hexagon head; designed to be used 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 Coarse (UNC) is a thread form with a 60 degree flank angle rounded roots and flat crests. For a given diameter it has a larger thread pitch than an equivalent diameter UNF thread. The unified thread is based on inch sizes and was first standardised in 1948 unifying the Whitworth and American standard thread forms

Unified National Extra Fine (UNEF) is a Unified thread form with a very fine (small) pitch that are typically used on instruments and parts requiring a fine adjustment.

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.

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.
