What are 12 point bolts called?
12-Point Flange Head Cap Screw
Also referred to as a 12-Point Flange Head Cap Screw, or a ferry bolt, the flange diameter and head thickness of the 12-Point Bolt are equivalent to the head dimensions of a socket head cap screw, thus permitting the 12-Point Bolt to be a replacement for any application that calls for a socket head cap screw.
What is a 12 point cap screw?
alloy steel, HOLO-KROME Flange 12-Point Screws are an alternative head design for. hex socket cap screws. The 12-point design allows for greater torque to be applied to the. fastener and have the ability to withstand stretching, deformation, and shearing under high. stress loads.

How do you specify a bolt?
The size of a metric bolt is specified using pitch, diameter, and length in millimeters. For example, in M8-1.0*20, the “M” means the Metric thread designation, the digit 8 refers to the Nominal diameter (in millimeters), 1.0 refers to the pitch, and 20 refers to the length.
What is better 6-point or 12 point?
Answer: It’s true that 12-point sockets are fine for most lightweight repairs, but heavy wrenching calls for a six-point socket. A six-point socket is much less likely to slip off a stubborn fastener or round over the corners. Here’s why: (1) Six-point sockets have thicker walls, so they’re less likely to flew.
What is the standard length of a bolt?
STANDARD THREAD LENGTH Bolt lengths ≤ 6”: Bolt lengths > 6”: Thread length = (2 X diameter) + 1/4” Thread length = (2 X diameter) + 1/2” Page 7 of 99 Page 7 of 99 Head Plow Bolts
What are the classifications of bolts and nuts?
External threads or bolts are designated with the suffix “A”; internal or nut threads with “B”. CLASSES 1A and 1B:For work of rough commercial quality where loose fit for spin-on-assembly is desirable. CLASSES 2A and 2B:The recognized standard for normal production of the great bulk of commercial bolts, nuts and screws.
