Other (usually smaller) sizes may occur to reduce weight or cost, including the small series flange bolts defined in ISO 4162 which typically have hexagonal head sizes corresponding to the smaller 1st choice thread size (eg. M6 small series flange bolts have 8mm hexagonal heads, as would normally be found on M5 bolts). [10]
The #6-32 UNC screw has a thread pitch of 1/32 in (0.031250 inches (0.7938 mm)).. The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm).
Cranks designed to mount three chainrings will almost always use two different bolt circle diameters; the larger to mount the two bigger, outer rings and the smaller to mount the smaller, inner ring. Most modern two-chainring cranks use either a 110 or 130 mm (4.3 or 5.1 in) bolt circle diameter.
Confusion can arise because each Whitworth hexagon was originally one size larger than that of the corresponding BSF fastener. This leads to instances where for example, a spanner marked 7 ⁄ 16 BSF is the same size as one marked 3 ⁄ 8 W. In both cases the spanner jaw width of 0.710 in, the width across the hexagon flat, is the same.
A hex key (also, hex wrench, Allen key and Allen wrench, Unbrako or Inbus) is a simple driver for bolts or screws that have heads with internal hexagonal recesses ().. Hex keys are formed from a single piece of hard hexagonal steel rod, having blunt ends that fit snugly into similarly shaped screw sockets.
Transit bolts are a type of bolt used to secure part of a mechanical appliance during transit. They are typically 4 to 12 in (100 to 300 mm) in length , although any size is possible as it depends on the type of device being transported.
