螺栓規(guī)格尺寸的內(nèi)容非常多，M代表三角螺紋，M后面的數(shù)代表公稱直徑，×號(hào)后面的數(shù)是表示螺栓去帽后的長(zhǎng)度。例如：M6×30M代表三角螺紋，6代表螺紋的公稱直徑是6，也就是說(shuō)是6個(gè)的螺紋，30代表螺栓去帽后的長(zhǎng)度。
There are many specifications and dimensions of bolts. M represents triangular thread, and the number behind M represents nominal diameter, × The number after No. is the length of the bolt after the cap is removed. Example: M6 × 30M represents the triangular thread, 6 represents the nominal diameter of the thread is 6, that is, 6 threads, and 30 represents the length of the bolt after the cap is removed.
由頭部和螺桿兩部分組成的一類緊固件，需與螺母配合，用于緊固連接兩個(gè)帶有通孔的零件。如把螺母從螺栓上旋下，又可以使這兩個(gè)零件分開(kāi)，故螺栓連接是屬于可拆卸連接。
A type of fastener consisting of head and screw shall be matched with nut to fasten and connect two parts with through hole. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolted connection is a removable connection.

國(guó)標(biāo)螺栓一般分為兩種：
GB bolts are generally divided into two types:
GB30螺栓、GB21螺栓，區(qū)別在于GB30的六角頭比GB21的要大一些。材質(zhì)均采用：Q235.等級(jí)為4.8級(jí)，硬度較弱，用于硬度要求低，不經(jīng)常活動(dòng)的部位，人們所謂的普通螺栓。典型的用途：機(jī)械業(yè)、建筑業(yè)、的固定、緊固。
The difference between GB30 bolt and GB21 bolt is that the hexagonal head of GB30 is larger than that of GB21. Materials: Q235. The grade is 4.8, and the hardness is weak. It is used for the parts with low hardness requirements and infrequent activities, which are called ordinary bolts. Typical uses: fixing and fastening in machinery industry, construction industry, etc.
M=螺紋的直徑 L=螺桿的長(zhǎng)度例如M24×70 就代表螺栓的直徑為24mm 螺桿長(zhǎng)度為70mm （不包括六角頭）。
M=diameter of thread L=length of screw e.g. M24 × 70 means that the diameter of the bolt is 24mm, and the length of the screw is 70mm (excluding the hexagon head).
