What are 12-point bolts called?

What are 12-point bolts called?

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 screw?

Twelve Point Flange Screws are an alternative head design for hex socket cap screws. The twelve point design permits this style bolt to be tightened down with a twelve point socket wrench, which permits higher torque to be applied as compared to a standard internal hex drive socket head cap screw.

What are 12-point bolts used for?

A lot of times, the 12-point bolts are used for a little higher clamp load. Typically, a 12-point bolt would be seen in the oil and gas industry because of the recessing head of the bolt. This will not be seen when they’re clamping together the end bolts. 12-point bolts are also prevalent in engine applications.

What does the M mean in screw size?

M = This designates the fastener is a metric size. 10 = The nominal diameter in millimeters. 1.0 = The thread pitch, or distance between threads, in millimeters. 20 = The fastener’s length, in millimeters.

Can a 12 point socket be used on hex head bolt?

Both 6-point and 12-point sockets can be fitted on hex nuts, the primary differences being convenience and torque. The more points a socket has, the more points of contact available. Compared with the 6-point socket, a 12-point socket has twice as many points, so it can more easily slide onto a hex nut.

Are 12 point bolts better?

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.

Is 6 point or 12 point sockets?

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.

Can I use a 12 point socket on a 6 point nut?

Compared with the 6-point socket, a 12-point socket has twice as many points, so it can more easily slide onto a hex nut. In other words, you would need to rotate only up to 30 degrees to fit a 12-point socket onto a hex nut. Torque power load is borne by the flanks of the nut or bolt instead of by the corners.

How do I know what size screw I need?

The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you’ll want to go with a #8 screw.

Do you really need 12 point sockets?

Is this really necessary? 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.

What do you use 12 point screws for?

Good for high-strength fastening, these screws are made from steel comparable in strength to Grade 9 steel. Use them for heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw.

What do 12 point flange head cap screws do?

Discover our collection of 12-point flange head cap screws, great for various machinery that relies on flange heads. These head cap screws work with all kinds of equipment in industrial fastening. With their 12-point design, they apply a larger amount of torque to a fastener, which can reduce the rounding of the hex socket.

What does a 12 point socket wrench do?

The 12-point head design means that this screw can be tightened with a 12-point socket wrench which allows higher torques to be applied as compared to a standard internal hex drive socket head cap screw.

Can a 12 point head cap be used as a ferry bolt?

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.
