Bolt vs Screw
A screw screws into something, a bolt joinsseveral things together from both sides of materials joined. Both a screw and bolt’s length is measured from the underside of the head to the end of the fastener.
A2/ 304 Stainless Steel
A2, otherwise known as 304 Stainless Steel is the regular stainless standard. It can resist intermittent weathering without corroding and loosing it’s metallic finish.
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 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.
