# Question: How Do I Know What M10 Bolt I Have?

## Is m6 the same as #6?

M6 refers to a metric 6 mm screw.

The outside diameter of the threads is 6 mm.

The standard metric rack screw is actually an M6 x 0.1 mm.

You can identify an M6 screw by measuring the diameter at slightly more than 7/32″ (0.228″)..

## What socket is close to 10mm?

10mm is a standard socket. But if you mean a set measured in inches, there is no exact equivalent. It is between 3/8 and 7/16.

## How can you tell if a bolt is stainless steel?

Stainless steel, in most cases, is non-magnetic. With bolts, stainless steel can be identified by the head marking. These markings indicate steel grade and tensile strength. When installed, stainless steel screws and bolts are known for their longevity.

## Are m10 and 3/8 the same?

Since 10 mm is bigger than 3/8″, the simple answer is, “NO”. But you CAN drill the hole out to either 25/64″ (for 3/8-24) or letter “X” (. 397″)( for 3/8-16), and tap for a Helicoil.

## What is M in bolt size?

The “M” designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres (e.g., an M6 screw has a nominal outer diameter of 6 millimetres).

## How do bolt sizes work?

To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.

## What does m8 1.25 mean?

For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.

## Is m8 the same as 8mm?

All dimensions of the bolt (and nut) are a parameter of its basic diameter. The “M8” refers to an approximation of the major diameter of the thread of 8mm – actually slightly less, like 7.9, as the sharp edges are rounded off.

## What size spanner fits a 10mm nut?

Spanner Sizes A 17mm spanner therefore fits a nut 17mm across its flats and this is normally a nut to fit a 10mm diameter bolt (M10).

## What are m8 screws?

M8 is the designation for a metric (M) sized bolt or screw that is 8mm (8) in diameter. This is roughly equivalent to a 5/16 bolt or screw.

## Is 5/16 The same as m8?

## Is SAE and UNF the same?

SAE Bolts, Nuts & Washers There are two general types of SAE bolts (sometimes referred to as machine screws). UNF (fine thread pitch) has more threads per inch than the same diameter bolt in the UNC (coarse thread pitch). Nut dimensions are maximums per SAE.

## What does m10 mean on a bolt?

6. Those are metric screw dimensions. M10 means a 10 millimeter outer diameter for the bolt or whatever piece it is; M12 means 12 millimeters. The part after the ‘x’ is the pitch — how many mm a thread is wide. To figure out which you have, you can measure the existing part with calipers and a thread gauge.

## How do I know what size bolt I have?

To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.

## Is m10 the same as 10mm?

31496″) The M10, about 10 mm in diameter, (. 3937″) and the M12 about 12 mm in diameter, (. 4724″). The “M” designates the bolt is Metric and the number after the M indicates the size.
