2024年11月19日 · To calculate the spanner size for a bolt, follow these simple steps: Metric Bolts: Multiply the bolt’s diameter by 1.5. For example, for an M10 bolt, the spanner size is typically 15mm (10mm × 1.5). Imperial Bolts: Match the bolt’s head size directly to the spanner size in inches or fractions.

Width across flats is the distance between two parallel surfaces on the head of a screw, bolt or nut. The width across flats will define the size of the spanner or wrench needed. The width across flats indicates the nominal "size" of the spanner.

Most lists of spanner sizes are divided into 2 rows, Nominal Size and Spanner size. There are a variety of spanners to choose from, such as: Hook spanners; Monkey wrenches; Open end spanners; Socket spanners; Adjustable spanners; All of these spanners can be used for different professional and DIY tasks and each has their own benefits.

2024年8月30日 · Below is a general guide for spanner sizes corresponding to standard metric and imperial nut sizes: M6 Nut: Spanner Size = 10 mm. M8 Nut: Spanner Size = 13 mm. M10 Nut: Spanner Size = 17 mm. M12 Nut: Spanner Size = 19 mm. M14 Nut: Spanner Size = 22 mm. M16 Nut: Spanner Size = 24 mm. M20 Nut: Spanner Size = 30 mm. M24 Nut: Spanner Size = 36 mm.

2023年11月14日 · Spanner size of piping and structural studs and bolts can be easily determined through PDF chart. In the PF chart, M size of bolt is written in the first column D size i.e. the OD dimension of the thread of the bolt is given

For example, an M10 bolt has a diameter of 10 millimeters. If you’re like me and typically measure bolt sizes by the head size (e.g., a 17mm bolt or nut head), it can often get confusing when trying to determine the actual spanner size required for a metric bolt. That’s where our handy Metric Bolt to Spanner Size Conversion Chart comes into play.

All the commonly used spanner and socket sizes,from 10BA up to 60mm with their decimal inch equivalents. This chart shows comparative sizes in increasing B.A, A.F, B.S.W, B.S.F and MM bolt or nuts and can be used for example to find the next size up or down where a spanner (wrench in USA) or socket is too tight or loose on a fixing.

Modern spanner sizes refer to the distance across the flats of the hexagonal nut or bolt they would fit. A 17mm spanner therefore fits a nut 17mm across its flats and this is normally a nut to fit a 10mm diameter bolt (M10). Also, hexagonal key sizes are given as the distance across their flats and so a M10 Allen Screw for example would need a ...

The size of a spanner corresponds to the head size of the nut or bolt it fits. For instance, a 10mm spanner fits a nut with a head 10mm across. Spanners come in various types, such as open-end, ring, combination, and adjustable, each designed for specific tasks.
