How is the length of a head bolt measured?
The length of a headed bolt is measured from the largest diameter of the bearing surface of the head to the extreme end of the point in a line parallel to the axis of the bolt. For example, square or hex head bolts are measured from under the head to the end of the bolt; a bolt with a countersunk head is measured overall.
How are square or countersunk head bolts measured?
For example, square or hex head bolts are measured from under the head to the end of the bolt; a bolt with a countersunk head is measured overall. The point of a bolt is always included in the measured length.
How are headless fasteners such as studs measured?
Headless fasteners such as studs are measured overall, including points, except for continuous- thread alloy studs made to ASTM Specification A193. This type is measured from first thread to first thread. Bolts have various styles of heads. Some of the more popular styles are illustrated above. styLes OF Head HEAVY HEADS AND NUTS
What’s the minimum length of thread for carriage bolts?
The only heat treatment normally available on austenitic stainless alloys is annealing, which is done at approx. 1900 Degrees (F) to a dead soft condition and is not normally thermally reversible. The minimum length of thread shall be equal to twice the basic bolt diameter plus .025″ for bolts <6″.

How is the length of a carriage bolt measured?
Carriage Bolts: Round Head, Short Neck (ANSI/ASME B18.5) – Length of a carriage bolt is measured from the underhead bearing surface to the extreme end of the bolt. A round head bolt with a short, square shoulder under the head, and a unified thread pitch.
How big of a hole do you need for a 16mm bolt?
This means that a 16mm bolt will fit through a 16mm hole but to allow for misalignment between parts it is common practice to drill bolt holes slightly larger. These are known as clearance holes. Typical clearance hole sizes are given in the table below along with the correct tapping hole size for each size of standard and fine pitch thread.
What are the dimensions of socket head fasteners?
An externally threaded fastener with unified threads, a cylindrical head (with a flat, chamfered top surface), knurled cylindrical sides and hexagonal recess. Head height is 50% of a standard socket head and the socket size is smaller.
